How to dispose of drilling cuttings is one of the problems facing the oil and gas industry. Oil and gas drilling operation generated large volume of drill cuttings and spent mud. Drill cuttings are produced as the rock is broken by the drill bit advancing through the rock or soil. Muds are circulated through the drill bit to lubricate and cool the bit.drill cuttings are usually carried to the surface by drilling mud and separated out by mechanical means, such as, shale shaker, mud cleaner.etcVertical Cutting Dryer

Drilling contractor have a variety of methods for dispose of these drilling wastes depending on what the local regulations allow and how costly those options. One effective equipment for drilling cuttings disposal is vertical centrifuge which can reduce the amount of OBM or SBM on cuttings discharge to reduce waste volume .Vertical Cutting Dryer uses centrifugal force to dry drilled cuttings that from shale shaker or mud cleaners. the cuttings are conveyed to the dryer through vacuum transfer or screw coneyors. Once cuttings are introduced into the dryer's charge hopper. The widely spaced, adjustable flights continuously direct cuttings to the screen surface. Flights within the cutting dryer creat a rolling action that promote further separation and prevents screen plugging. Under high G-force created by the large cone diameter,Liquid and solids separation occurs instantly as cuttings make contact with the finer-mesh centrifuge screen while producing cleaner return fluid and drier solids discharge.The solids discharged from cutting dryer can also be collected for further disposal. such as thermal treamtent. useful fluids reclaimed by cutting dryer is collected and pumped to decanter centrifuge for final processing and resuse in the active mud system.

In the request for improved environmental practices, operators need solutions that take liquids/solids separation to a new level. The vertical centrifuge from KOSUN incorporates a high –speed vertical cuttings dryer that achieves maximum liquids/solids separation in large-volume processing .It gives operators a critical advantage in meeting increasingly stringent environmental regulations for onshore and offshore cutting disposal.

The KOSUN 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. KOSUN Vertical Centrifuge can reduce total discharged OOC below 6%, which is currently the discharge limit in many areas of the world, in many areas of the world, our goal is 5% total.

In China solids control industry, KOSUN is a
