Recently one set of vertical cuttings dryer and decanter centrifuge are ready for shipment to international drilling company. The standard oil based drilling cuttings treatment system including vertical cuttings dryer GNCD930F and decanter centrifuge GNLW363C-VFD, with flushing pump, centrifuge feeding pump, telescopic skid, fluids collection tank, screw conveyor system, waste container, etc.
The F version vertical cuttings dryer is the lastest version vertical cuttings dryer, It is the ideal equipment for oil based drilling waste management system, the working principal is normally as below:
The screw conveyor collect the drilling cuttings from solids control equipments, such as shale shaker, desander, desilter, another screw conveyor which is installed slantly, to transfer the cuttings to vertical cuttings dryer feeding port. The fluids flow to the intermediate tank and the submersible slurry pump or screw pump will transfer the fluids to decanter centrifuge to separate fine solids. The solids discharged from vertical cuttings dryer with oil on the cuttings below 5%, it can be landfilled for disposal or to be sent to further treatment TDU. The fluids treated by decanter centrifuge can be recovered and back to solids control system storage tank, it can be used to prepare for new drilling fluids or sent to third party waste water treatment facility to get clear water.
To treat water based mud drilling waste, we need to use high G drying shaker instead of vertical cuttings dryer, the G force is up to 8.0 G to get drying cuttings, the fluids will be feed to decanter centrifuge, the VFD control panel can control 3 motors frequency and control the bowl speed, screw conveyor speed, pump speed ( to adjust the feeding flow rate). All of the 3 inverters are made from world famous brand electrical components for easy outsourcing locally. We can provide CNEX, ATEX, IEC EX explosion proof standard for option.
