KOSUN DC Series Centrifuge Used in many Industrial Applications

Decanter centrifuge is one of the equipment in solids control system on oil field. There used to be 3 overload safety protection on KOSUN DC Series centrifuge. One is the safety protection device of the gear box, second is the hydraulic coupler overload protection, third is the control panel with over currency protection. Nowadays as we change the drilling centrifuge structure there are 2 protections. One is hydraulic coupler overload protection to protect the bowl and the other is control panel protection to protect the screw conveyor.

Decanter centrifuge is used in many industrial applications such as: Oil /solids separation,Industrial and biological wastewater treatment, food processing,Fish processing, Chemical slurry.The decanting centrifuge slurry is fed through a stationary pipe, which is inside a hollow shaft connected to a screw conveyor or scroll.The slurry enters a feed compartment located inside of the conveyor and is forced through discharge nozzles to the bowl section.Once inside the bowl, centrifugal force causes the material to separate.The screw conveyor moves the solids to the tapered end where they are discharged.Clear fluid flows out the other end.Some decanter centrifuges are powered by a motor and gearbox combination. The gearbox provided the correct speed and torque to drive the solid control centrifuge.

KOSUN DC series decanter centrifuge is used in separating suspension of solids phase with particle diameter（d≥2μm） for drilling mud and fluids handling. Ruggedly built for oilfield and industrial services, it is especially effective in environmentally sensitive areas.Drilling mud decanter centrifuge, in which there is no physical separation between the solid and liquid phase, rather an accelerated settling due to centrifugal acceleration.With all the mentioned features, KOSUN decanter centrifuge can meet with different requirements of mud treatment for various industry.

Six Steps to Install Drilling Fluids Decanter Centrifuge

Decanter centrifuge is really one of the most useful machines, because it has found wide application in many industries. The commonest industries include oil well drilling, biological wastewater treatment, food processing, chemical slurry and other fields. It is used to extract particles from liquids.

KOSUN Drilling Mud Decanter Centrifuge efficiently removes undesirable solids from drilling mud in crude oil extraction. The decanting centrifuges are designed specifically to remove unwanted solids and fine particles from virtually all kinds of used drilling mud, including those based on water/synthetics and conventional oil-based drilling fluids.

Six Steps to Install Drilling Fluids Decanter Centrifuge:
1. Drilling solids decanter centrifuge ought to sit far from the inlet of mud pump for a full agitation in the mud.
2. Firm installation of drilling solids decanter centrifuge is important, so its 4 legs ought to be fixed on the surface of tanks with bearing bars.
3. Its installation also involves protruding the discharge groove from the tanks and connecting it with hydraulic supply line for a better performance of sand discharge.
4. Mud pump ought to stand behind desander and desilter, and connect tightly with feed pipes and inlet pipes.
5. Join together the flushing feed pipes and perforated pipes on inlet pipes and the tank.
6. Plug in and switch on all the parts of drilling solids decanter centrifuges for the sake of repairing safety.

Much current centrifuge application with drilling fluids is not only unproductive, but is counterproductive. One example of misuse is the practice of running two centrifuges in parallel to "recover the barite" with the first and "discard the drilled solids" with the second. The first stage is traditional centrifuging, returning the underflow to the active mud system. Rather than discarding the overflow, it is routed to the second centrifuge running at a higher speed, where the low-gravity solids supposedly are discarded and the "clean" liquid is returned to the mud.

Common Faults and Solutions for KOSUN Decanter Centrifuge

When it comes to heavy industry, such as oil & gas field, the decanter centrifuge is applied as the solids control equipment or solids-removal equipment to separate the cuttings from drilling mud. This is indispensable in oil drilling operations, while the drilling mud pumped from wellbore presents high salinity and strong corrosiveness which asks for high efficient centrifuge with good corrosion-resistance. In order to achieve the efficient performance, the core components including helical blade, outlet and inlet, should be optimized with wear resistance of cemented alloy.

The Needs of a High Quality Mud Tank System

In drilling operation, mud tank is the last but not least equipment, we can use drilling mud tanks system in various drilling. The different well drilling conditions will request different fluids system. Drilling fluids system includes mud tanks system and the mud process equipment. All pipelines and electrical lines, cables, and all accessories, such as, the ladders, hand rails, guard rails, etc. KOSUN drilling mud tank in oil drilling fluids solids control system often rectangle shape with H shape steel as the main frame, skid mounted after satisfying the strength requirement.

High quality mud tank system must be fabricated under professional configuration. The optimal proposal with high efficiency and low cost. Catering to clients’ specific demand and actual drilling conditions, all the equipment and tanks should be made of high quality raw material and produced according to executive standard and inspect all equipment and tanks completely and strictly.

Vertical Cuttings Dryer is the Mostly Used Important Equipment for Drilling Waste Management

As we all know, vertical cuttings dryer is the mostly used important equipment for drilling waste management. It is also called VERTI-G cuttings dryer. KOSUN vertical cuttings dryer has been proved with excellent performances during drilling waste disposal process.

The vertical cutting dryer is a machine designed to reduce the operator’s total fluids cost and limit waste disposal volumes. This is achieved by directly recovering the fluids from the cuttings, and by recovering any weighted mud from the shaker screens avoiding that it can be lost due to a failure of the shaker, a movement of the rig or the occlusion of the screen. The machine helps meet certain fluid-on-cuttings discharge requirements that must be abided by.

VERTI-G dryer can effectively treat the water-based, oil-based, and synthetic-based drilling mud, generate very dry drilling cuttings, reduce the discharge volume of drilling cuttings and recover precious drilling mud, so as to improve comprehensive drilling cost-effectiveness. The vertical centrifuge independently developed and manufactured by KOSUN features with mature performance, including super strong separation ability.

With top feeding mode and built-in high speed centrifugal drum, it can achieve the maximum handling capacity of 60T/h, and the OOC of drilling cuttings after treatment is lower than 5%. The liquid phase can also be recovered after being treated by the centrifuge at the next level. In such way, waste pollution caused by oil-based drilling mud can be satisfactorily solved, and oil-based or synthetic-based drilling mud can be saved.

Vertical Centrifuge Helps Meet Drilling Cuttings Discharge Requirements

The vertical cuttings dryer is a machine designed to reduce the operator’s total fluids cost and limit waste disposal volumes. This is achieved by directly recovering the fluids from the cuttings, and by recovering any weighted mud from the shaker screens avoiding that it can be lost due to a failure of the shaker, a movement of the rig or the occlusion of the screen. The machine helps meet certain fluid-on-cuttings discharge requirements that must be abided by.

Vertical Centrifuge is the ideal product for oil based drilling waste management. A stainless steel screen bowl traps “wet” solids and accelerates them up to 820 RPM with G force up to 360. Liquid is forced through the screen bowl openings, while “dry” solids are extracted by the angled flights attached to the cone, which rotates slightly less slowly than the bowl.

The Vertical Centrifuge (VC) is a continuous screen type centrifuge with automatic feed control designed for liquid-solid separation. The Vertical Centrifuge (VC) is designed to recover the liquid phase of the drilling fluid from drilled solids by exposing the latter to very high centrifugal acceleration forces which improve fluid separation from the drill cuttings. By further clarifying the costly liquid phase which can be returned to the active drilling mud system, the machine helps save money on the expensive drilling fluids. Often shaker screens get clogged and, as a result, expensive mud is lost overboard. The Vertical Centrifuge (VC) system catches any lost mud and returns it to the active mud system. The recovery systems work well with diesel, mineral and synthetic oil based mud.

The Major Benefit of the Hi G dryer Technology

Hi-G dryer is also can be used for oil based mud drilling waste treatment; vice versa, vertical cuttings dryer can also be used for water based mud drilling cuttings management. Based on this, KOSUN design it's vertical centrifuge which can be used for both WBM and OBM drilling waste treatment.

The hi-g dryer independently developed and manufactured by KOSUN features with high G-force vibration intensity (adjustable) and excellent screening and drying effect. The frame angle can be adjusted from -1° to +5° via AWD angle adjustment system in continuous operation state. The liquid ratio of drilling cuttings can be reduced to below 10% after treatment, significantly reducing drilling waste discharge costs.

The major benefit of the Hi G dryer technology, sometimes overlooked, is the elimination of whole mud losses from the shaker. This historically has ensured that the shakers were never run at their optimum capacity and thus the solids control system efficiency was adversely affected. Incorporating the Hi G dryer down steam allows the shakers to be run close to maximum capacity without the concern of whole mud losses.

Hi-G Dryer is also referred to as drying shaker. Besides, Vertical Centrifuge, screw conveyor, decanter centrifuge, screw pump and other auxiliary equipment can also be effectively used for drilling waste disposal.

Difference Between the Shaker Screen and Hi-G Dryer

Hi-G Cuttings Dryer shares the same construction with shale shaker except its base height. The base of High-G Dryer is bigger than shale shaker. The difference between the shaker screen and Hi-G Dryer focuses their processing materials shale shaker processes the drilling mud and the High-G dryer deals with discharged drilling waste separated by solids control equipment.

The drying shaker is actually a vibrating dryer sieve, pour shelves 10 °, in order to reduce the loss of liquid. 4 vibrating screen mesh using a three-dimensional detail of the waveform screen, instead of the conventional flat-line screen, three-dimensional structure allows the force of gravity down into the oncoming solid fold groove, away from the projection area, from each of the a fold of the upper solids separation. By thus increasing the amount of fluid, not drown the convex portion, the convex portion to increase the fluid flow capacity. Two layers of fine screen cloth is attached to the upper layer of coarse screen cloth, three screen cloth bonded together, made of corrugated and then bonded to the openings of the board. Waveform overlay screen area than ordinary flat screen area increased by about 40%, compared with flat screen about 2 to 3 fine sieve size. Fluid-handling capacity increased by 70% and not prone to clogging, the treatment effect is very good.

Zero waste discharge still remains a bit away after going through the previous four steps, therefore solidification, thermal desorption, cuttings reinjection and biodegradation will be utilized to push towards the goal as the last step.KOSUN Hi-G Dryer can recover water- and oil-based mud in drill cuttings with fluid phase down below 10% and remarkable reduction on waste discharge cost. It is especially good at managing oil-based drill cuttings.

KOSUN Drilling Waste Management Processing Flow Line

KOSUN DWM Solids Control launched a relative solution by the integration of domestic,and foreign drilling waste management experience and methods as well as the consideration of drilling waste production process. KOSUN drilling waste management systems can treat oil base mud, water base mud. It’s obvious to know, in order to get a better separating performance we need to treat the oil base mud and water base mud separately. KOSUN waste management systems are composed of cuttings dryer and decanter centrifuge.

Drilling Waste Management Processing Flow Line:
The waste cuttings discharged from the primary shale shaker and mud cleaner is delivered to the cuttings dryer or Hi G dryer shaker through screw conveyor or Vacuum pump. The filtrate and solid would be separated in the cuttings dryer and dryer shaker. The drier solids out from this 2 device would be environmental friendly to discharge directly or transported off-site for further treatment. The liquid is transferred by screw pump to the high speed centrifuge to remove the much fine solids. There may need flocculation process to let the extreme fine solid gather together for easy separation in decanter centrifuge.

Vertical Cuttings Dryer System for Drilling Waste Management

VERTI-G cuttings dryer is a machine designed to reduce the operator’s total fluids cost and limit waste disposal volumes. This is achieved by directly recovering the fluids from the cuttings, and by recovering any weighted mud from the shaker screens avoiding that it can be lost due to a failure of the shaker, a movement of the rig or the occlusion of the screen. The machine helps meet certain fluid-on-cuttings discharge requirements that must be abided by.

The drying shaker is designed and manufactured to work safely. This large high-speed rotating machine requires care and understanding for maximum safety. Unsafe practice in maintenance and operation will cause conditions, which are hazardous to both personnel and property.

The vertical centrifuge independently developed and manufactured by KOSUN features with mature performance, including super strong separation ability. With top feeding mode and built-in high speed centrifuge drum, it can achieve the maximum handling capacity of 60T/h, and the OOC of drilling cuttings after treatment is lower than 5%.

The vertical cuttings dryer system catches any lost mud and returns it to the active mud system. The recovery systems work well with diesel, mineral and synthetic oil based mud. The system has proven to be more efficient with synthetic systems due to the ease of oil separation from larger cuttings. Synthetic systems also have a higher mud value, which makes the machine more attractive from an economical point of view. In addition, the system reduces the amount of wastes at the rig site and the resulting disposal costs.

KOSUN VERTI-G Cuttings Dryer can Meet Increasingly Stringent Environmental Rules

KOSUN VERTI-G cuttings dryer improves overall cost-efficiency by recovering costly drilling fluid that is recovered from cuttings, as well as whole mud lost from shaker failure and rig motion. Further, the VERTI-G cuttings dryer produces lower waste volumes by generating dryer solids in both oil- and synthetic-base drilling fluid systems. The reduced waste volume can in turn dramatically reduce disposal costs.

VERTI-G dryer gives operators a critical advantage in meeting increasingly stringent environmental rules for cuttings disposal. The flow of cuttings into the VERTI-G cuttings dryer is PLC-controlled and continuously fed to yield optimum liquid/solid separation. Once cuttings are introduced into the dryer’s charge hopper, widely spaced, independently adjustable flights continuously direct cuttings to the shaker screen surface. Flights are tungsten carbide coated to reduce abrasion and ensure optimum tolerance.

In these operations, drill cuttings and associated waste fluids are collected on the rig in cutting boxes and then sent back to shore for disposal or treatment prior to disposal. Even when the discharge of drill cuttings offshore is still allowed. There is often now a requirement to collect and transport drill cuttings on the rig for secondary process such as vertical cutting dryer that will reduce the volume of drilling fluids associated with cuttings prior to discharge. In the drilling waste management or some similar works, screw conveyor or auger is a necessary part to convey materials from base ground to a higher position for further treatment.

Drilling Mud Decanter Centrifuge is Widely Used in Separating Smaller Solid

Decanter centrifuge can be used on drilling site to separate suspended solids with particle diameter larger than or equal to 2μm and treat the drilling mud and fluids. It serves as the last-stage drilling mud solids control equipment, applicable for treating unweighted and weighted drilling mud.

When used to treat unweighted drilling mud, centrifugal separation process is very effective for drilling mud with low solid phase. Decanter centrifuge of large treating capacity is suitable for such purpose. It can deal with 23~45m3 liquid each hour, processing 3~4t solid phase. The decanting centrifuge separates the drilling mud into underflow and overflow. The large quantity of useless solid phase contained in the underflow is discharged into waste pool, and the precious liquid phase is returned into the drilling mud tanks. Since the drilling mud with low solid phase can bring immeasurable economic benefits, the drilling mud decanter centrifuge is more and more widely used to remove the solid phase in unweighted drilling mud.

Decanter centrifuge is widely used in drilling mud separation to separate smaller solid particles after the equipment processing such as drilling mud shale shaker and drilling fluids mud cleaner or desander and desilter. Usually, decanter centrifuge is equipped with screw pumps or slurry pumps to feed drilling mud to the centrifuge. Correct and proper operation and good condition make sure that drilling mud decanter centrifuge operate ordinarily with high performance. Next, in this essay, expedient measures to maintain drilling fluids will be closely described by steps.

Working principle of Vertical Cuttings Dryer in Drilling Site

The Vertical centrifuge gives operators a critical advantage in meeting increasingly stringent environmental rules for cuttings proposal. The Vertical Centrifuge improves overall cost-efficiency by recovering costly drilling fluid that is recovered from cuttings, as well as whole mud lost from shale shaker failure and rig motion. Further, the Vertical Cutting Dryer produce lower waste volume by generating dryer solids in both oil and synthetic-base drilling mud system. The reduced waste volume can in the turn dramatically reduce disposal cost.

Wet cuttings enter the vortex at the top of the unit and fall into the inner separation area. The conical screen basket within the unit rotates, producing an increasing G-force as the cuttings are forced downward and outward of up to 360 times the natural gravitational force (G-Force). As associated mud separates from the cuttings under the induced gravitational forces within the unit, the openings in the screen allows recovered fluid to pass through and exit the unit.

The vertical cuttings dryer improves overall cost-efficiency, producing reduced amounts of extremely dry cuttings for disposal and recovering valuable fluid for reuse. It is effective with water-, oil- and synthetic-base drilling fluids. Offshore and onshore projects where the recovery of valuable drilling fluid from cuttings, as well as recovery of whole mud lost from shaker failure, rig motion and screen blinding are priorities.

KOSUN Vertical Centrifuge Uses Centrifuge Force to Dry Drilled Fluid

With the improvement of environment protection awareness of the public, in the drilling site, the advanced new technology are urgently needed in promoting the effectiveness of drilling waste management both in domestic and international drilling market.

The Vertical Centrifuge (VC) is a continuous screen type centrifuge with automatic feed control designed for liquid-solid separation. The Vertical Centrifuge is designed to recover the liquid phase of the drilling fluid from drilled solids by exposing the latter to very high centrifugal acceleration forces which improve fluid separation from the drill cuttings. By further clarifying the costly liquid phase which can be returned to the active drilling mud system, the machine helps save money on the expensive drilling fluids. Often shaker screens get clogged and, as a result, expensive mud is lost overboard. The Vertical Centrifuge system catches any lost mud and returns it to the active mud system. The recovery systems work well with diesel, mineral and synthetic oil based mud.

KOSUN vertical cuttings dryer uses centrifuge force to dry drilled solids in oil or synthetic base fluids. A stainless steel screen bowl traps “wet” solids and accelerates them up 900 RPM. Liquid is forced through the screen bowl openings, while “dry” solids are extracted by the angled flights attached to the cone, which rotate slightly slower than the bowl. Tungsten carbide protects the flights from abrasive solids and ensures long operational life. This aids in maintaining a constant gap between the scroll and screen bowl, which is crucial for proper operation. KOSUN Cuttings Dryer has been done with strict balance testing for all major rotary components to minimize vibration & noisy.

Drilling Waste Management System Would Reduce at the Source

KOSUN DWM Solids Control launched a relative solution by the integration of domestic,and foreign drilling waste management experience and methods as well as the consideration of drilling waste production process. Drilling waste management system(DWM Solids Control) would reduce at the source, i.e. purify the drilling fluids and take away the solids at the source by application of solids control system. Then, dewatering of discharged waste, water treatment, water recycling and purification would work altogether to minimize water content in waste and recycle the water.

For finding application downside throughout water-base mud drilling cuttings treatment, KOSUN makes series technical improvement to ancient vertical centrifuge, like providing intelligent impulse jet system, etc. And second generation vertical centrifuge VC-2000 and third generation mini kind vertical centrifuge VC-800 are developed. The VC-2000 square measure below service for water-base mud drilling waste management comes with smart performance feedback.

The VERTI-G cuttings dryer can process varying amounts of drill cuttings and fluids, up to 60 tons (61 metric tons) per hour. Dry solids discharged from the dryer are typically <5% oil content by wet weight.Afterwards, KOSUN drilling waste management companies have euipment which Hi-G dryer and vertical cuttings dryer would continue with dewatering and mud/gas separator to minimize waste disposal. At last, the discharged waste would be reasonably and effectively treated by means of solidification, biodegrade, thermal desorption and cuttings re-injection.

As part of our drilling waste management services, we also supply highly skilled staff to ensure equipments are installed correctly and that they are fully operational and well-maintained. Our employees, who trained to provide support swiftly, are on-call worldwide 24 hours a day, everyday, to be available at a moment’snotice.

DWM Solids Control is an Important Part of Reducing Waste

Compared to onshore processing, higher offshore drilling waste disposal costs. Some oil and gas fields for oilfield waste treatment specified dedicated landfill; in other areas, the operator of DWM Solids Control can meet the discharge standard drilling waste management shipped out of the city or shipped to fill industrial drilling waste management field. The vertical cuttings dryer features a state-of-the-art design that can process varying amounts of cuttings and fluids, typically up to 60 tons per hour. Dry solids discharged from the dryer are typically≤5% oil content by wet weight. More stringent cuttings-discharge regulations have pressured operators and drilling contractors to reduce drilling waste volumes and recover premium products for reuse.

Abandoned drilling liquid separation process an important part of reducing waste in the greater proportion of the water content, the volume of solids means the residue under smaller, the required processing fees can be smaller, you can effective control processing costs, reflecting the economic benefits. China in recent years has developed a filter press plates, filter dewatering conveyor belt, horizontal spiral centrifuge dewatering equipment, promote the improvement of drilling waste management technology.

DWM Solids Control is impossible to a fixed device and effective wastewater treatment processes different fields, conventional treatment processes and equipment Pharmacy greater dependence, and DWM Solids Control is in dealing with the nature of the big differences of Auger between each other high suspended solids, high COD, high salt, high color and other characteristics of the drilling waste water cost is very high, DWM control which determines the drilling sewage treatment plant on the current world the diverse nature.

KOSUN can Customized the Drilling Waste Treatment Equipment

In drilling operations, typical solids control equipment discards 1-4 barrels of liquid for each barrel of solids removed.Studies have shown that the cuttings dryer can recover one bbl. of fluid, for each 2.5 bbl. of solids exiting the Vertical Dryer. This recovery is measured after processing through the solid bowl-decanting centrifuge.

For finding application downside throughout water-base mud drilling cuttings treatment, KOSUN makes series technical improvement to ancient vertical centrifuge, like providing intelligent impulse jet system, etc. And second generation vertical centrifuge VC-2000 and third generation mini kind vertical centrifuge VC-800 are developed.

Drilling processes in the oil & gas industry usually generate two primary types of wastes, namely drill cuttings, and used drilling fluids. Most of these wastes associated with oil & gas drilling activities can cause significant hazards to the environment. Hence, to minimize the impact on the environment, these wastes need to be effectively treated and disposed. Universally, countries have employed various regulatory measures to tackle this challenge. The methods used to store, mix-bury-cover, land-spread, and biodegrade drilling waste require extensive drilling waste management and significant land disturbance, and licensees using these methods are required to reclaim affected sites.

At present, oversea countries with advanced oil industry commonly count for drilling cuttings waste management technology development. From last century, according processing equipment and facility is still on the head line of the world. There are complicated drilling cuttings portions, steady cuttings character and complicated processing situation, thus it decides the diversity of drilling waste management information system in the international drilling cuttings management.

KOSUN Vertical Centrifuge Uses Centrifugal force to Dry Drilled Solids

Vertical centrifuge is also called vertical cutting dryer, it is an innovative design which fits for oil-based drilling waste management. Drilling cuttings from the primary solids control equipment like shale shakers or mud cleaners are picked up by screw conveyor ( auger ) and transfered to feeder of the vertical cutting dryer.

The VERTI-G dryer gives operators a critical advantage in meeting increasingly stringent environmental rules for cuttings disposal. The flow of cuttings into the VERTI-G dryer is PLC-controlled and continuously fed to yield optimum liquid/ solid separation. Once cuttings are introduced into the dryer’s charge hopper, widely spaced, independently adjustable flights continuously direct cuttings to the shaker screen surface. Flights are tungsten carbide coated to reduce abrasion and ensure optimum tolerance.

The KOSUN Vertical Centrifuge uses centrifugal force to dry drilled solids in oil or synthetic base fluids. A stainless steel screen bowl traps “wet” solids and accelerates them up 900 RPM. Liquid is forced through the screen bowl openings, while “dry” solids are extracted by the angled flights attached to the cone, which rotate slightly slower than the bowl. Tungsten carbide protects the flights from abrasive solids and ensures long operational life. This aids in maintaining a constant gap between the scroll and screen bowl, which is crucial for proper operation. KOSUN Cutting Dryer has been done with strict balance testing for all major rotary components to minimize vibration & noisy.

KOSUN is the leader in domestic solids control industry and expert in waste treatment. We are capable of providing customers with such three series as oil & gas drilling solids control equipment, centrifuges and drilling waste treatment equipment.Since its establishment in 1992, it has been working on continuous development of solids control and drilling waste treatment technologies.

Vertical Cuttings Dryer Reduce the Drilling Waste Pollution

Vertical cuttings dryer is a high-speed vertical dryer that achieves maximum liquids/solids separation in large-volume processing. Vertical cutting dryer gives operators a critical advantage in meeting increasingly stringent environmental regulations for onshore and offshore drilling waste management disposal.The vertical cuttings dryer features a state-of-the-art design that can process varying amounts of cuttings and fluids, typically up to 60 tons per hour. Dry solids discharged from the dryer are typically≤5% oil content by wet weight.

Vertical centrifuge can be used to reduce the liquid content of drill cuttings to a level that allows discharge to the environment or as preparation for bio-remediation. Discharge criteria may be economically driven but are more often driven at a local level by legislative requirements. This will typically be expressed as retained oil on cuttings (ROC) or oil on cuttings (OOC) discharge criteria the extractor also functions insurance against whole mud loss from the shakers.It is able to capture and return valuable drilling fluid to the active system should the oilfield drilling rig.

Zero waste discharge still remains a bit away after going through the previous four steps, therefore solidification, thermal desorption, cuttings reinjection and biodegradation will be utilized to push towards the goal as the last step. Hi-G dryer: KOSUN Hi-G Dryer can recover water- and oil-based mud in drill cuttings with fluid phase down below 10% and remarkable reduction on waste discharge cost. It is especially good at managing oil-based drill cuttings.

Drilling waste management with regard to CSM usually just select shale shaker, desander as well as desilter with regard to 3 stage cleansing. However the recycled dirt denseness may rises or more since the good solids cant individual away through desilter to ensure that the centrifuge may needed or even depart the actual dirt as well as combining brand new dirt once again.

How to choose the right shale shaker screen for the shale shaker?

For drilling fluid shale shaker, the shale shaker screens is reproductive structure principally device, it principally will take away the solids that are larger than the screen mesh openings. The drilling fluid with little solids would flow through the screen meshes, and right down to the mud tank for the any purification. Whereas the massive solids or the cuttings would stay the screen, and be vibrated and flow to the discharge finish of the shaker basket. Thus it's extremely necessary to settle on a correct screen in step with the solids diameter, mud gravity, consistence & density etc. As improper screen choice will cause loss of pricey drilling fluids, premature pump failures, overloading of different solids removal instrumentality like a centrifuge, shrunken instrumentality life, reduced rate of penetration and high issues within the well bore.
