In order to meet customers’ request and to help solve the problems faced in front of customers from the more and more strict environmental protection rules, GN Solids Control designed and put into market a comprehensive design for the oily sludge separation unit, and now GN Solids Control is leading in this industry.
In recent 3 years, GN Solids Control has customized several sets of similar systems, and such systems are being used in many different countries both in domestic China and overseas. It is widely used for treating the discharged slurry and sands from crude oil tank cleaning, oily waste discharged from refineries, and the viscosity oily waste from solids control for oil and gas drilling. It helps to reduce the cost for waste transportation and oil recycle, and gained good comments from under users.

OILY SLUDGE SEPARATION

A complete system is combined by several sections:
1. Pre heating and pre mixing system. In this system, a mixing tank with heating facilities are being employed. A chemical dosing system is used for adding some polymer or something else into the oily sludge and heating is used for reducing the viscosity. Later, the sludge is to be treated by a shale shaker, by which the large particles are separated out.
2. A high speed decanter centrifuge is used in next step for treating out the fine particles from the liquid. Floating unit is kind of oil water separation, and the light of weight oil will float on surface of liquid and it would be scraped out to an oil tank. The settled down particles would be drained from bottom of the IPC unit.
3. A disc centrifuge is used to separate out the small amount of particles from the liquid, and further separate the oil from water. Then the water flows into the water tank, while oil flows into the oil tank.
In the complete system, by using the complicated manifold and valves, the end user can bypass or invite into loop some equipment based on the sludge’s condition.
