GN Solids Control is one of the few companies who can produce both big bowl decanter centrifuge and vertical cutting dryer for drilling waste management. But GN Solids Control never ceases to improve, early this year, GN has applied several new applications on its vertical cutting dryer, and the new 3rd generation vertical cutting dryer was proved to have better performance in factory and on jobsite.

Vertical cutting dryer is always positioned as first step treatment for drilling cuttings from oil and gas solids control system. A screw conveyer is used to collect solids discharges from shale shaker, desander, desilter and medium speeded centrifuge. Vertical cutting dryer’s working principal is just like the procedure when washing machine drying the wet clothes.

GNCD930C in waste management system

GN vertical cutting dryer

After researched many previous cases of vertical cutting dryers’ job performance, per customers’ feedback, even world famous vertical cutting dryers have the problem of blocking the meshes. GN engineer team designed below new applications:

1. air knife for GNCD930C vertical cutting dryer
2. scrapers with rubber protections for GNCD930C vertical cutting dryer

Air knife helps to blow the solids stuck in mesh holes and avoids blocking, while scraper helps the solids to fall off the mesh. Those applications greatly enhanced efficiency of GNCD930C vertical cutting dryer.

The new GNCD930C vertical cutting dryer was proved to have excellent performance both in factory and on oilfield jobsite, and is suitable for both OBM and WBM.

Drilling waste is drilling mud comes out from well with drilling cuttings. The drilling mud can be water based or oil based usually. As to environment regulations these drilling waste can not be disposed directly. GN Solids Control offers equipments in drilling waste management to help customers solve the problem.

There are 2 main equipments respectively used for water based mud and oil based mud. GN Hi G Cutting Dryer Shaker used for waters based mud and GN Vertical Cuttings Dryer is used for Oil based mud.

 

 

The GN Hi-G Dryer Shaker is with long shaker deck big capacity which is used for waste management to treat the drilling cuttings from the primary solids control equipments, like shale shaker, desander desilter to dry the solids for transportation, and make the fluids easier for further treatment.

The GN Vertical Cutting Dryer 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 890 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. GN cutting dryer has been done strict balance testing for all major rotary components to minimize vibration & noisy.

 

Besides the 2 equipments above GN Solids Control has Delivery system to move cuttings.  GN Solids utilize a custom designed and constructed Screw Conveyor (Auger) as part of drilling waste management system. The Auger is designed with 12 feet per section which makes it to be standard spare parts for exchange with each other. The screw material utilized by GN is abrasive material which lasts longer than our competitors.

 

 

 

 

 

 

 

Finally, GN Solids Control has Decanter centrifuge to polish the Dryer and Hi G Shaker effluent.  The Cuttings Dryer and Hi G shaker effluent is typically collected and pumped to a highvolume decanting centrifuge for further cleaning. The decanting centrifuge separates the slurry into fine solids and “cleaned” fluid, which is often sent back to the active drilling fluid system. A portion may be used as dilution for the  Dryer and Hi G shaker. The solids from the centrifuge can be collected in the same vessel or conveyor as solids from the Dryer or Hi G shaker.

GN Solids Control provides customers with good quality drilling waste management equipment and gives customers best solution on drilling waste treatment. Please do feel free to contact us for more information.

Vertical cuting dryer is a very important part for drilling waste management on oil base mud treating. Decanter centrifuge will be the second equipment to clean fluid after vertical cutting dryer

Vertical Dryer Working Principal

The GN Vertical Cutting Dryer 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 900RPM. 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.

China Vertical Cutting Dryer Manufacturer

GN Vertical Cutting Dryer fixed with individual oil lubrication system with automatic alarm for pressure limit. The main motor and oil pump motor is interlocked with each other for avoiding the start of the main motor prior to the start of the oil pump motor.

Other than vertical cutting dryer, GN Solids Control also produce other solids control for a complete solids control pakage including shale shaker, desander , desilter , decanter centrifuge, centrifugal pump, mud agitator, mud tank, jet mud mixing,etc. Please contact us freely
