KOSUN Screw Conveyer can be used in Drilling Waste Management Projects

Nowadays many more environmental regulations limiting or banning the discharge of various types of drilling fluids and associated drill cuttings globally. The drilling contractors started to utilize "zero discharge" or "ship to shore" drilling operations. 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 cuttings 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.

A screw conveyer or auger conveyer is a mechanism that uses a rotating helical screw blade, called a “flighting“, usually within a tube, to move liquid or granular materials. They are used in many bulk handling industries. Screw conveyors in modern industry are often used horizontally or at a slight incline as an efficient way to move semi-solid materials, including food waste, wood chips, aggregates, cereal grains, animal feed, boiler ash, meat, bone meal, municipal solid waste, and many others. The design of the conveyor is dependent on operating conditions, the type of transported material and its properties. Traffic enforcement can be controlled by changing the speed of propulsion.

KOSUN screw conveyer can be used in drilling waste management projects, providing an effective, low-cost drilling cuttings transport system for onshore and offshore drilling facilities. Adopting 12-feet (3.66m) multi-sectional composite structure, the screw conveyor can be flexibly assembled on different drilling sites, with characteristics of simple operation, stable structure, strong adaptability and high safety, so as to significantly improve the working efficiency of equipment and reduce the costs and resources. The blade of screw conveyor adopts wear-resistant material to ensure its service life. The screw conveyor is designed on basis of strict safety standards. Grille shield is provided on its U-shaped chute to prevent foreign materials from entering, to guarantee the operator’s safety. The frame at bottom can protect and support the screw conveyor, ensuring its structural stability.

Drying Shaker is a kind of shale shaker which is mainly used for drying drilled solids , and the feeder is a little different from normal shale shaker.

Drilling Fluid Solids Control Centrifuge can Meet With Different Requirements

The mud separation process between solid phase and liquid phase is completed in the roller. Decanter centrifuge separation principle is to use high-speed rotating roller driven into the mud in the high speed rotating drum, mud was dumped into the wall to form a liquid circle, solid phased particles of liquid ring get greater than its own gravity for undreds or even thousands of times the effect of centrifuges force, will overcome the resistance of the slurry viscosity to the roller on the inner wall of rapid subsidence formed solid layer, liquid forming liquid layer.

Actually, in drilling rig solids control system centrifuge is the most complicated one. It is rather difficult for operator get leagal operation, etc. However, in long term its important position is following shale shaker subsequently. At the beginning, centrifuge used in solids control process for drilling fluid is from chemical or food industry. No matter the separation particle size or treating capacity can’t meet drilling fluid process requirements.

KOSUN oilfield drilling mud decanting centrifuge can meet with different requirements of mud treatment under various drilling condition, that can do sedimentation and separation for particles more than 2 um. After treatment, the mud can achieve ideal viscosity and proportion, results in better recycling, high efficiency, saving and environment protection.

Working Principle of Drilling Decanter Centrifuge uesed in Drilling Waste Management

KOSUN DC Series Decanter Centrifuge is used to separate suspended solids ≥2μm in diameter and treat the drilling mud and fluids. It is especially effective when used in oilfield service industry, industrial service industry and especially in environmentally sensitive areas. This type of centrifuge is high in recovery rate, effective in solids control and remarkable in the reduction of cost spent on drilling mud resupplying and management. It is a very sophisticated dynamic balancing machine, able to operate stably with the whirling speed ranging from 0 to 3900 and generate centrifugal force of 3000G.

KOSUN DC Series Decanter Centrifuge can meet with different requirements of mud treatment under various drilling conditions, that can do sedimentation and separation for particles more than 2 μm. After treatment, the mud can achieve ideal viscosity and proportion, resulting in better recycling, high efficiency, saving and environment protection.

   

DC Centrifuge is driven by two motors. The main motor drives the drum and the outer casing of differential through belts while the auxiliary motor, after the differential shifting speed, drives the spiral propeller. This will make the drum and the spiral propeller rotate in the same direction with a certain differential speed. 

The series of decanting centrifuge by our company has been developed many years with the continuous improvement and optimization design, which possesses the characteristics of good result of separation and settlement, as well as large quantity, reliable work, longer life, lower energy consumption, easy maintenance, smooth operation, lower noises, etc. 

To ensure that the effective treatment result and long service life, the important parts adopts high quality stainless steel, forging material, strengthen heat treatment and strict control processing. And on each part that easily wears take spraying wear-resisting layer and mosaic of hard alloy, etc. The overflow of the main drum mouth using adjustable poling board, it can be adjusted anytime according to different sludge treatment. 

To meet the requirements of the development of modern drilling engineering, KOSUN developed and equipped with the explosion-proof variable frequency control system which could adjust separation factor and drum rotational speed. By this new technology, make the centrifuges adapt property changing of mud during the operation process, that makes the treatment more effective and perfect. 

A VFD ( Variable Frequency Drive ) module monitors and controls both the main and back electric drives. The operator can manage bowl and scroll speeds via a touchscreen that also displays input from the various sensors, including temperature, current, rotational speed and vibration.

KOSUN High-speed Vertical Dryer can Reduce Environmental Impact

KOSUN vertical cutting 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.

Mainly Features of Vertical Cuttings Dryer:
1. Maximum screen speed 800 rpm (350 G’s);
2. Maximum inner cone flights is 790 RPM;
3. Both are driven by (1) 1750 RPM motor (but different diameter pulleys);
4. Maximum flow process rate 40ton/hour. When flight’s thickness is below 50 mm they should be changed;
5. Enables compliance with Regulations on Retention on Cuttings discharge (R.O.C.).

Reducing environmental impact (OBM discharged to the environment):
The Vertical Cuttings Dryer System can reduce total discharged OOC below 5.0%, which is currently the discharge limit in many areas of the world. However our goal is to reduce the percentage even further.

Improved economics (cost savings):
1. As a result of recovered OBM being returned to the mud system, the drilling fluid recovered provides a huge saving to the client with OBM cost.
2. Recovering mud and ultimately reducing the volume of waste generated, also results in the cost associated with hauling off waste being greatly reduced.

Drilling fluids vertical cutting dryer could be regarded as a vertical centrifuge, the discharged cuttings transferred by the auger get into the screw conveyor. Drilling fluid vertical cutting dryer from the opening on the top, under the function of centrifugal force produced by rotation of the screen module. Liquid flow out from the opening at the flank side while the solids discharged out from the outlet at the bottom of the cutting dryer. The discharged solids water content is around 30%, that means there is no flowing water, so it could be transported easily.
