This week, a full package of compact oily sludge separation system was finished from GN factory in Beijing China. The compact design fast movable oily sludge treatment system is purchased by a reputable Environmental Solutions Company from China domestic market.

There are 3-stage separation equipment included in the oily sludge treatment system.

1) There is a 2-panel small footprint shale shaker equipped in the system for coarse solids separation. The model is GNZS752. As mostly, the oily waste come out from different sources and it is mixture of different wastes. There may be big size solids in side. The big sides solids may block or even broken the centrifuges. The small size shale shaker is used to remove the possible big size solids in the sludge.

2) There are 2 centrifuges in the oily sludge treatment system. The first centrifuge we call it decanter centrifuge. The decanter centrifuge model is GNLW224, it is a 2-phase separation centrifuge. The 2-phase decanter centrifuge is help to remove solids or soil from liquid mixture. The 9 inch centrifuge is a min size decanter centrifuge. The bowl diameter is only 9 inch, but the bowl length and diameter ration is up to 4. The longer ration can help to get cleaner liquid. It is the smallest centrifuge from GN Solids Control for industry separation.

3) The second centrifuge inside the oily sludge treatment system is disc centrifuge. It is also called 3-phase centrifuge. As the name mean, the disc centrifuge can separation oil, water and soil.

Many people may wonder: in case the disc centrifuge can separate and get oil, water and soil. While you add 2-phase decanter centrifuge inside the system? Really, the 2-phase decanter centrifuge is surely not to increase the cost. The disc centrifuge can only allow liquid mixture with liquid content less than 3%. Otherwise, it will damage the centrifuge. While the decanter centrifuge can allow liquid with solids content up to 15% ~ 20%. Decanter centrifuge is a necessary as pre-separation before disc centrifuge.

Thermal desorption unit is normally known as TDU. It is a kind of Ultimate equipment for oily waste management. The Thermal desorption unit (TDU) is a High-tech products, few company has the capability and technology to make it.

GN Thermal Desorption Unit is an ex-situ, non-incineration technology. It is designed to separate hydrocarbons from various matrices including oilfield drilling cuttings waste, oil based drill cuttings, oily contaminated soil, oil sludge and sand, filter-cake, tank and tanker bottoms, organic-based hazardous waste and contaminated soil in a non-oxidizing atmosphere without destroying the hydrocarbons. The TDU technology has been used extensively for waste management, the main function is for recovery of the oil from the waste material as a sellable product throughout the world.
Many clients showed great interest on the design of GN Thermal desorption unit (TDU) technology. There are mainly 2 designs developed by GN Solids Control.

From 2015 to June, 2016, GN Solids Control have been working on the design of the drum type TDU. But GN stopped that project after 2016. After that GN Solids Control shift to design the screw type TDU from July, 2016. So now, GN Solids Control does not make drum type Thermal desorption unit (TDU).

GN Solids Control latest design on is similar to TPS, but not TPS, TPS is a single screw in one tube, with different tubes.

GN Solids Control design is as following:
1) One tube, two auger system for self cleaning, it’s better than the single tube system.
2) Temperature can go up to 700 C degree which suits the drilling cuttings and oil sludge to recovery oil and water.
3) GN Solids Control have a dust removing unit before condensing, so it makes it easier for oil water, solids separation.
GN Solids Control already have the major components, like tube material, burners, air lock valves and Fin-Fan coolers etc in the factory to shorten the manufacturing time.

For any questions, please contact GN Solids Control sales team for support.

GN Solids Control is the world’s leading manufacturer of solids control equipment and mud recovery systems. As a leading manufacturer of shale shakers, mud cleaners, decanter centrifuges, cutting dryers, centrifugal pumps, etc., GN’s brands and products are available. More and more international customers are recognized. The GND system consists of a two-layer mud shaker, two hydrocyclones, a centrifugal pump, a tank and an electrical control system. The system can effectively separate solids and liquids, reduce the solid waste content in the drilling mud, make the cuttings drier, easy to transport, environmentally friendly and easy to handle. The entire system is very compact and armored, very economical and value for money.

We have been working hard to develop different markets for our Oil Sludge processing systems. The scope comes from waste management companies, drilling waste treatment companies, and oil companies and oilfield service companies. The first stage separation of the system is a two-layer mud vibrating screen. When the mud enters the lower layer of the screen, large solids will be separated from the mud. Fine solids and mud will fall into the tank, and the mud will pass through the centrifuge. The pump draws in two hydrocyclones that work like a sand remover to separate the solids size to 40 microns. The solids separated by the hydrocyclone will fall onto the upper deck of the shale shaker and the solids will be further dried for disposal. The clean mud separated by the hydrocyclone will fly back to the tank and be pumped back to the wellbore for reuse and recycling. The basic configuration of the mud recovery system is a two-layer mud shaker, two hydrocyclones for sand removal, a centrifugal pump, a mud tank and some other components.
