Versatility and high-performance of KOSUN VERTI-G dryer
Usually, Vertical Centrifuge (VC) is applied in the plant followed by solids control and separated drilling mud can also be injected into the mud circulation system and recycle the barite in the drilling mud. Matched equipment such as Hi-G dryer, screw pump, decanter centrifuge and screw conveyer are composed of the whole drilling cuttings waste management system.
Drill cuttings are conveyed from the shakers to the VERTI-G cuttings dryer through a variety of site-engineered conveyance systems that include
- Gravity feed
- CLEANCUT pneumatic transfer
- Vacuum transfer
- Screw conveyors
The flow of cuttings into the VERTI-G dryer is PLC-controlled and continuously fed to yield optimum liquid/ solids separation. Once cuttings are introduced into the dryer's charge hopper, widely spaced, independently adjustable flights continuously direct cuttings to the screen surface. Flights are tungsten carbide coated to reduce wear and ensure optimum tolerance.
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.
The VERTI-G cuttings dryer improves overall cost-efficiency by recovering costly drilling fluid that is recovered from cuttings, as well as whole mud lost from shaker failure and rig motion. Further, the Vertical Cutting Dryer produces lower waste volumes by generating dryer solids in both oil- and synthetic-base drilling fluid systems. The reduced waste volume can in turn dramatically reduce disposal costs.
