Drilling waste management system contains several equipment and tank to make a full solution including vertical cuttings dryer for dry drilling cuttings , decanter centrifuge to recycle drilling fluids out of vertical cuttings dryer , screw pump for feed decanter centrifuge and flush outlet of vertical cuttings dryer , air compressor to supply air for air knife on vertical cuttings dryer , screw conveyor to transfer drilling cuttings , mud tank and work plat form to make all process continuously .
Vertical cuttings dryer is one of the core equipment and will dry drilling cuttings with fluids content bellow 5 percent at 900 RPM rotating speed tank body . The screen can be use 0.25 to 0.5 mm size depending on requirement , one set of air knife will be needed to match vertical cuttings dryer which is powered by one set of air compressor . One set of screw pump will be needed to flush outlet fluids to keep sure fluids will be flow out when high viscosity and density . There will need minimum 2 sets of screw auger to feed drilling cuttings into vertical cuttings dryer , one set horizontal to collect drilling cuttings from shale shaker , desander and desilter , another one to feed drilling cuttings to vertical cuttings dryer .
One set high speed decanter centrifuge to recycle drilling fluids that recycled by vertical cuttings dryer at 2 to 5 microns separate at 3200 RPM bowl speed . one set of VFD control panels is optional , the VFD control panel will change speed of centrifuge bowl from 0 to 3200 RPM but quite big size . If you want small footprint , then you can choose one set of fixed speed decanter centrifuge .
Other than the vertical cuttings dryer and decanter centrifuge , there will be other equipment to cooperate like screw pump , tank , work form , etc .
