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.

Tandem shale shakers are shipped to Middle East Oilfield Service Company this week, the technical configuration is as below:
1) 2 single deck shale shaker installed on one tandem skid, with possem belly. When loading in the container, the single shale shaker will be packed by wooden pallet separately, the skid will be fixed by special made frame, the possem belly will be protected by plastic flim and disassembly to fit to the container size.

2) The 2 tandem shale shaker treating capacity is up to 1200gpm for drilling fluids of both WBM & OBM & SOBM. We can provide the shaker screens with API NO. from API 20 to API 325 as per clients’ requirement. The shaker screens are composite material frame shaker screens for longer working life and larger screen area. Each single shale shaker is equipped with 3pcs shaker screens for free.
3) The shaker deck bottom is made of stainless steel 304 for better corrosion resistance of the fluids touch part. The shaker skid is made of high grade structure steel. The screens are locking by the wedges for fast replacement of the shaker screens, the user do not waste much time to replace the shaker screens, and the screens working life is average 300 hours, it reduces the times to replace the screens.
4) The compact design is for convenient transportation from one rigsite to another.
We can also produce the triple shale shakers as per the client’s requirement, to install 3 units of linear motion shale shaker on one oilfield skid. The explosion proof vibration motor and starter could be CNEX, ATEX OR IEC EX for option as per the different requirement.
If you require shale shaker, mud cleaner, decanter centrifuge, vacuum degasser, pls contact with GN solids control, we can also produce customized tandem shale shaker.

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.
For more information about the full hydraulic drive decanter centrifuge, pls contact with GN solids sales.

Recently GN solids control shipped vertical cuttings dryer, decanter centrifuge system to Russia drilling companies, they are installed inside the 40ft container to keep them warm and avoid frozen of the drilling cuttings when working in Winter.

The client use the vertical cuttings dryer system for oil based drilling cuttings, when they use water based drilling cuttings, we will use different system design with high G drying shaker and decanter centrifuge, and we have standard design of pitless system for both water based mud and oil based mud ( also for SOBM), the client only need to buy one system and use them in different rig site.
The VFD decanter centrifuge GNLW363C-VFD is the most popular decanter centrifuge used for solids control system and drilling waste management system, oil sludge treatment system, dewatering system, solids water separation system and waste water treatment system. The VFD control panel is positive pressurized VFD control panel with PLC smart control and HMI interface, the inverter for main motor, back drive motor and feeding pump motor are made of ABB or Siemens brand or Schneider brand for global outsourcing.

The bearing is SKF brand, the screw  is made of stainless steel with heat treatment up to 1000 degree, the impeller is protected by tungsten carbide tiles for longer working life and easily replacement. The mud distribution port and solids discharge port are all protected by tungsten alloy and interchangebale. The bowl material is duplex stainless steel 2205 or 2304 by centrifugal casting, it is much better than SS304 and SS316.
