This week, GN solids control finished the fabrication of 10 sets decanter centrifuge for one client from Middle East. All the decanter centrifuges are VFD model with high standard IEC explosion proof for hazardous area with wide temperature scope application. This is a repeated order from the client; actually, repeated orders take a large part in GN’s sales. That is the positive response from client on GN product.
The annual oil festival, the 2019 Beijing Petroleum Exhibition is about to close. At the CIPPE oil show, GN exhibited a strong product lineup. Including: oily sludge treatment system, solid vacuum pump, shale shaker, big bowl high-speed decanter centrifuge, centrifugal pumps, shaker screens, screw conveyor, vertical cuttings dryer.
Among them, the oily sludge treatment system has received extensive attention from customers. With the gradual landing of national environmental protection policies, the demand for oily sludge treatment equipment is growing. GN oily sludge treatment system is an efficient treatment process. It is widely used to treat tank bottom sludge, refinery sludge, drilling cuttings and so on. The treatment method is mainly by heating and chemical washing, and then removes big sand by shale shaker, the decanter centrifuge, and the three-phase centrifuge for oil, water and soil separation. The oil obtained after separation can be sold to the refinery, the water can be reused in heat washing system. The oil content of the solid phase is less than 2%, which can be further processed by thermal desorption or biodegradation to an oil content of less than 0.3% to meet the requirements of harmless treatment.
Another product that has received widespread customer attention is the solid vacuum pump. The solid vacuum pump is a product developed by GN in the recent year for the solid and high solids material transportation in the petroleum industry. It is characterized by strong self-priming ability, long transport distance, and ability to transport solids and high solids materials. The solids vacuum pump is widely used in clearing operations, cuttings transportation, oily sludge transportation, and remote transportation of mud.
Regarding drilling solids control and drilling waste management, GN optimized the design of shale shakers, decanter centrifuges, and drill cutting dryers. The optimized shale shakers are with fast screen changing, and the screens are repairable, which greatly prolongs the service life of the screens. Moreover, it can be equipped with a vacuum adsorption device to more effectively improve the recovery of drilling fluid and reduce the cost of drilling waste disposal. According to the market demand, GN has developed a big bowl, high speed, large aspect ratio decanter centrifuge for mud dewatering treatment and more effectively treat the aging drilling fluid. As a well-known manufacturer of drill cutting dryer, GN drill cutting dryer is further optimized to prevent material blockage and reliability.
This week, GN finished the fabrication of tandem shale shakers for one Middle East oilfield service company. Now the equipment is ready for shipment. The tandem shale shaker is to put 2 unit single shale shakers on one skid. Normally these two unit shale shakers are completely same to ensure the easy operation and maintenance in future.
GN Solids Control just finished one batch of equipment for a customer from Middle East. The order list includes several fully hydraulic drive decanter centrifuge, feeding pumps and 80+ mud agitators.
Currently, GN is able to provide the industrial decanter centrifuge with wide range of bowl size from 9 inch to 30 inch. GN fullyhydraulic drive decanter centrifuge is running by using the hydraulic pump to transfer the oil to drive the bowl and scroll.
Vertical cuttings dryer and decanter centrifuge are main equipment in drilling waste management system. They are used to make the drilling waste cuttings much dryer and recover more drilling fluids for reusing. By using the cuttings dryer, the drilling company could reduce the drilling cost on consumption of drilling fluids base liquid. And the discharged much dryer cuttings could be easily transported. In the same system, cuttings dryer and centrifuge are installed in the same line but one after another in working procedure.
Vertical cuttings dryer is always located beside the solids control system. Fed by the auger conveyer, the cuttings dryer treat the oil based drilling cuttings with capacity of 30-50 tons per hour. Cutting discharged from primary solids control shale shaker is always wet with flow-able fluids. After treated by GN vertical cuttings dryer, the oil content on cuttings will be less than 5%.
