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.

Feeding system of the vertical cuttings dryer has been a problem for the operators, normally there are several ways for feeding:

1.Vacuum unit or vacuum collection system for transportation of drilling cuttings:

Working together with diaphragm pump.

2.Screw Conveyor system:

Screw conveyor is composed of electric motor, gear box, screw or auger, bracket, coupler, feeding hopper, solids discharge port, cover, etc. They are often used horizontally or at a slight incline as an efficient way to move the drilling cuttings from solids control system.

3.Peristaltic pump

A peristaltic pump is a type of positive displacement pump used for pumping the drilling waste to the top hopper of the vertical cuttings dryer from the cuttings collection hopper.

The 3 ways of feeding system may be adopted to different conditions according to the jobsite situation. When there is enough place and enough financial support, you can choose vacuum unit together with 2 units of screw conveyor, one is installed horizontally and the other one is installed inclined. But for compact design, hose shear pump might be an ideal choice.
