Recently GN solids control shipped vertical cuttings dryer, decanter centrifuge system to Russia drilling companies, they are installed inside the 40ft container to keep them warm and avoid frozen of the drilling cuttings when working in Winter.
The client use the vertical cuttings dryer system for oil based drilling cuttings, when they use water based drilling cuttings, we will use different system design with high G drying shaker and decanter centrifuge, and we have standard design of pitless system for both water based mud and oil based mud ( also for SOBM), the client only need to buy one system and use them in different rig site.
The VFD decanter centrifuge GNLW363C-VFD is the most popular decanter centrifuge used for solids control system and drilling waste management system, oil sludge treatment system, dewatering system, solids water separation system and waste water treatment system. The VFD control panel is positive pressurized VFD control panel with PLC smart control and HMI interface, the inverter for main motor, back drive motor and feeding pump motor are made of ABB or Siemens brand or Schneider brand for global outsourcing.
The bearing is SKF brand, the screw is made of stainless steel with heat treatment up to 1000 degree, the impeller is protected by tungsten carbide tiles for longer working life and easily replacement. The mud distribution port and solids discharge port are all protected by tungsten alloy and interchangebale. The bowl material is duplex stainless steel 2205 or 2304 by centrifugal casting, it is much better than SS304 and SS316.
The vertical cuttings dryer is ideal equipments to treat the oil based drilling cuttings, after treatment, the oil on the cuttings is below 5%, sometimes it is even below 3%, it could meet the disposal limit for most countries, if the use needs the oil on the cuttings lower than 1%, the thermal unit should be applied.
