GNOST-05A Oil Sludge Treatment Plant for Asia Client

BY gnadmin 13 April 2019 Uncategorized

Recently 1 set of oil sludge treatment plant is almost ready for shipment to Asia client, it is under testing in our facility before shipment. The treating capacity for oil sludge separation is 5 m3/h. We also have standard or customized designed oil sludge separation system with 1 m3/h and 15m3/h for option.

The general working process is as below:
GN sludge vacuum pump transfer the oil sludge from the waste pit/pond to the pre-mixing modular, the pre-mixing tank equipped with heating lines which can heat the oil sludge to increase the flowability of the oil sludge and increase the separation efficiency of the shale shaker, decanter centrifuge. By adding the chemicals, it will also increase the efficiency of the further process steps. 2 mud agitator and one submersible slurry pump are installed on the pre-mixing tank with electric control system.
Then the pre-treatment oil sludge is transferred to the shale shaker to separate the coarse solids by the submersible slurry pump, it also reduces the solids content of the oil sludge so that the centrifuge could separate the fine solids easily. The shaker screen is specially made with big opening to separate coarse solids to protect the decanter centrifuge.
The screw pump feed the oil sludge to the decanter centrifuge, the discharged fluids is flow to the 3 phase centrifuge to separate the oil and water. The clean water and pure oil is flow to the buffer tank , which will be pumped to the oil storage tank and water storage tank. The water can be used for the circulation again.
The 20ft container loading dewatering unit will be used when necessary with decanter centrifuge, the chemical jetting is to make the oil mixture easily separated by the decanter centrifuge.
If you need a customized solution for waste oil sludge treatment, pls contact with GN sales for more information.

BY gnadmin 1 April 2019 Uncategorized

GN solids control just come back from CIPPE 2019 oil exhibition in Beijing, China. We showed our advanced technology and equipments at the CIPPE oil show. Below is the photos taken in our stand.

1) Sludge Vacuum pump: it is the ideal pump to transfer the waste cuttings, waste sludge, oil sludge, drilling mud, cement, powder material and other industrial waste.
2) High G force drying shaker with 4 panel composite material shaker screens. The screen dimension 585x1165mm, we can install the shaker screen with API mesh size from API 20 to API 325 comply with API RP13C. The G force is up to 8.0G.
3) 14 inch bowl decanter centrifuge
4) 22 inch bowl decanter centrifuge for waste water treatment and waste sludge treatment and dewatering unit, the bowl diameter is 550mm, the bowl length is 2310mm, different with the normal drilling fluids treatment centrifuge, the GNLW554 series centrifuge can treat the discharged water much cleaner, it is ideal centrifuge for the project required very clear water.
5) Oil sludge separation system : The configuration is as below:
The Premixing tank, coarse solids separation shale shaker, decanter centrifuge, three phase centrifuge, chemical dosing unit, fluids buffer tank, shaker fluids collection tank, oil tank, water tank and complete skid. The mud agitator and heating lines installed on the premixing tank.
6) Vertical cuttings dryer for oil based drilling cuttings treatment.
7) Screw conveyor to transfer drilling cuttings to vertical cuttings dryer drilling waste management system
We got a lot of inquiries and positive interests for the oil sludge treatment unit. The working video for the oil sludge treatment is as below: By using proper chemicals, we can design the customized system for different requirement. If you need to know more information, pls get the brochure from our sales engineer.

Hydraulic drive decanter centrifuge manufacturer in China

BY gnadmin 17 March 2019 Uncategorized

As the reliable manufacturer of hydraulic drive decanter centrifuge in China, GN solids control recently shipped several units of Full Hydraulic Drive decanter centrifuge with feeding pump to Middle East, together with over 80 units of centrifugal pumps.

When we start production in the second factory in Dachang Chaobai River Development area, we introduced one batch of advanced machine to produce decanter centrifuge and vertical cuttings dryer, also for the centrifugal pump. We have high speed balancing machine, low speed balancing machine for balancing of centrifuge bowl. We can produce decanter centrifuge with 9 inch bowl, 14 inch bowl, 18 inch bowl, 22 inch bowl, 30 inch bowl for option, we have fixed speed centrifuge and VFD decanter centrifuge for different applications, also when used in high temperature weather area, for heavy drilling fluids, the user will need full hydraulic drive decanter centrifuge, compared with VFD decanter centrifuge, the hydraulic drive centrifuge is much easier to adjust the differential speed to reach better performance of the centrifuge treatment.

The feeding pump of the decanter centrifuge is positive displacement pump made by Germany Netzsch, it works steadily to feed the drilling fluids to the decanter centrifuge, the speed of the pump motor could be adjusted by PLC smart system so that the feeding flow rate will be controlled according to the client’s requirement.

4. The centrifugal pumps are widely used to transfer the drilling fluids, waste sludge, dredging slurry, oil sludge, etc. different materials and industry waste water. The major wear parts of the centrifugal pump is pump casing, impeller, the material of impeller and pump casing made by GN solids control is hard ductile iron alloy for longer working life and better wear resistance.
