GN Oil Water Separator can be used to remove free non-emulsified oils, diesel, gasoline and fuels from waste stream by coalescing media. Because of its high capacity and easy operation, oil water separator is popular for primary Oil Water separation project, including groudwater remediation, vehicel wash racks, stormwater treatment, Oil Production and Spill Recovery, etc.

GN Company Oil Water Separator capacity ranges from 6m3/h to 262 m3/h, and the material can be stainless steel and carbon steel.

Working Procedure of GN Oil Water Separator

1) Oil Droplets Coalesce

Waste water feeding into oil water separator and flowing through a tightly stacked bundle of coalescing media. The coalescing media expands the surface area of the oil water separator giving the free oil more space on which to coalesce. As the oil droplets accumulate on the coalesce media and turned into larger droplets. Later on the larger drop flow up the surface of the media, detach and rise to the water surface. Because of the difference gravity of oil water and solids, so they can be separated.

2) Oil Decants to Oil reservoir

Surface oil decants by gravity into a segregated oil reservoir to be removed from the tank.

3) Solids Slide down to sludge chamber

Since the solids gravity is bigger than water, the solids will slide down the surface of the media into the sludge chamber at the bottom of the tank for removal when it’s necessary.

4) Clean water collection

After that, the oil free relatively clean water travels under an oil reservoir baffle, over an adjustable weir and into a clean water effluent chamber which will be discharged from this chamber by gravity.

Welcome to visit GN factories, and do trail test within our work plant.

There is one set of Drilling Cuttings Dryer System working at client's work site in Xinjiang, China, for his oil based drilling cuttings' project.

GN Company is a professional manufacturer of Drilling Mud Solids Control Equipment, Drilling Waste Management Equipment, and Oil Sludge Treatment Equipment for 11 years, with head office & 3 factories in China (close to Beijing).

GN Company Vertical Cuttings Drier

Drilling Mud is used for Oil & Gas Drilling Project, and there would be much solids/soil in the drilling mud from the drilling well. We manufacture equipment for removing Solids/Soil from drilling mud, and then clean drilling mud can be reused for drilling project. The equipment are named Drilling Mud Solids Control Equipment.

Drilling Waste is waste separated out from Drilling Mud Solids Control Equipment, and there are Oil Based Drilling Waste, and Water Based Drilling Waste. There are still big amount of valuable material, which can be reused for drilling project, which saves a big cost for the operation companies.

For Oil Based Drilling Waste, we suggest Vertical Cuttings Drier + Decanter Centrifuge.

For Water Based Drilling Waste, we suggest High-G Shale Shaker + Decanter Centrifuge.

GN Company Centrifuge

GN Company's equipment includes Decanter Centrifuge, Shale Shaker, Vertical Cuttings Drier, Desander, Desilter, Mud Cleaner, Centrifugal Pump, Sludge Solid Vacuum Pump, etc.

GN Company has branch companies both in Russia and USA, with equipment & spare parts stocking in warehouse in Houston.

Welcome to contact GN Sales Managers for more technical specifications and working video.

There are Decanter Centrifuge, Mud Shakers, and Mud Cleaner are well packed and ready for shipment from GN No.1 work plant, for drilling project in Russia.

GN Company, as a professional manufacturer of Solids Control Equipment, including Decanter Centrifuge, Mud Shaker, Desander, Desilter, Mud Cleaner, Vertical Cuttings Drier, etc.

GN Shale Shaker

GN Company has been manufacturing Decanter Centrifuge for 11 years, its production line includes Bowl Diameter 220-760mm, Bowl Length 670-3328mm, with ajustable bowl speed and screw speed, 0-4500RPM. And it’s necessary for some projects that the Electrical Control Parts, such as pump, electrical control cabinet, shall be explosion proof, and GN can supply based on CNEX, ATEX, IEX standard.

GN Decanter Centrifuge

Decanter Centrifuge’s working procedure is as below,

Feeding slurry into decanter centrifuge by Centrifuge Feeding Pump or other pump.

Within the decanter, both screw conveyor and Bowl rotate at a high speed, that would generate Centrifugal Force, so solid and liquid would be separated.

Because of the different speed of Bowl and Screw Conveyor (Bowl Rotating Speed is more quickly), Solid would be discharged from Cone end, while Liquid would be discharged from another end.

GN has supplied equipment to about 70 countries, with 70% of sales amount from the International Market, including UK, Holland, Australia, USA, Canada, Brazil, UAE, Kuwait, Oman, etc.

GN has two factories under operation, and a third one under manufacturing now, with more than 100,000 square meters totally.

GN has two branch companies in USA & Russia, with equipment & spare parts stocking in warehouse in Houston.
