Application and Economics for KOSUN Vertical Cuttings Dryer

Flights within the VERTI-G dryer create a rolling action that promotes efficient separation and prevents screen plugging. Under high G-forces created by the large cone diameter, liquid/solids separation occurs instantly as cuttings make contact with the finer-mesh, high-capacity centrifuge screen. The end result is clean return fluid and dry solids discharge.

Application
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.

Problems
More stringent cuttings-discharge regulations have pressured operators and drilling contractors to reduce drilling waste volumes and recover premium products for reuse.

Solutions
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.

Economics
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.

The ES-KSN oilfield drilling vertical centrifuge returns and recycles large percentages of SBM (Synthetic Base Mud) and OBM (Oil Base Mud) to an active system which in the past was lost as waste products to the environment. ES-KSN oilfield vertical cutting dryer can reduce total discharged OOC below 5%, which is currently the discharge limit in many areas of the world, in many areas of the world, our goal is 5% total OBM discharge to the environment, and our goal is not only to reach 5%, but also reduce the percentage further.
