The VERTI-G Cuttings Dryers http://www.kosun.us/drilling-waste-management/hi-g-dryer.html/ makes its contribution with its innovative process after the shale shaker completes its task. Cuttings that pass over the shaker typically have an average of 30% to 50% ROC (Retention on Cuttings) when they enter the proprietary auger system and begin to cycle through the VERTI-G cuttings dryer. The initial processing is done with a vertical cutting dryer that utilizes centrifugal force to take advantage of their differing densities to separate the largest portion of the remaining drilling fluid from the cuttings. The processed cuttings are discharged from the vortex dryer into the adjacent shale bin, and then have an average ROC between 4% and 7% once processing is complete. This ROC percentage represents cuttings suitable for immediate disposal requiring minimal if any further stabilization. Processed waste material is lighter, less toxic and is a more cost-efficiency.

Due to increasingly stringent environmental requirements around the world, the cost impact of drilling waste management for oil based drilling operations is steadily increasing. This puts a large focus on the ability to efficiently clean, transport, and dispose of cuttings, while maximizing fluids recovery. Historically, a successful dill waste management operation would require a large on site footprint, further increasing operator pad construction costs. As the importance of driling waste management system increases throughout the industry it is necessary to have a solution that can continue to deliver field-proven results while reducing operator liability and cost.

Vertical Cuttings Dryer 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 KOSUN VERTI-G cuttings 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 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.
