shale shaker

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.

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.

GN solids control showed our equipments at Petrotech 2019 in India from Feb. 10th to Feb. 12th. The equipments we showed at the oil show in India including:


1) Sludge vacuum pump: it can be used to transfer drilling cuttings, powder cement, waste sludge, oil sludge, drilling fluids, industry waste water, mining tailings, dredging slurry, sand, even for animal waste, etc. Especially for high viscosity sticky oil sludge from refinery crude oil tank bottom, the vacuum pump is an ideal equipments to transfer the oil sludge, but the flow rate will be different with the normal flow rate. Depends on the different conditions oil sludge, we will choose the proper model for our clients according to the question list they filled.


As a 100% air operation pump, the vacuum pump do not need any electricity to operation, this is pretty convenient in some jobsites when electricity is limited, the user can use the air compressor in the jobsite to provide air for the vacuum pump, they can choose automatic operation or manually operation for their requirement.
2) Centrifugal pump: the complete centrifugal pump is consist of pump head, coupler for motor end, coupler for pump end, electric motor, control panel, skid and other accessories. The pump head is the most important components for the centrifugal pump, our pump head and all the parts are interchangeable with world famous brand centrifugal pump.
3) Shale shaker: the 2 panel shale shaker is the smallest model we have now, we have 2 panel, 3 panel and 4 panel single deck shale shaker for option, also we have dual deck shale shaker for special purpose.

This week GN solids control shipped one batch of solids control equipments to Russia, the client inspect the equipments in our factory in Beijing before dispatch to Russia. We welcome all the clients to visit our factory before order and after order before delivery.


The solids control equipments they ordered including linear motion shale shaker, mud cleaner, decanter centrifuge, centrifugal degasser, this is their repeat orders since 2017, they keep repeating orders every month during the past years, and make mud tanks system locally. Sometimes they replace the old equipments from their existing rig solids control system.


The shale shaker, mud cleaner, vacuum degasser/ centrifugal degasser, decanter centrifuge are our main products and the most popular products, we have many options for decanter centrifuges with different size from 9 inch to 30inch for different applications, for each bowl size, we have 2 models with different ratio. For 9 inch bowl size centrifuge, we have GNLW224D and GNLW224E-VFD, for 14 inch bowl centrifuge, we have GNLW363C, GNLW363-VFD, GNLW364C-VFD, for 18 inch bowl centrifuge, we have GNLW452, GNLW453C-VFD and GNLW454D-VFD , for 22 inch bowl centrifuge, we have GNLW553C-VFD, GNLW554D-VFD for option, for 30 inch bowl centrifuge, this is the max centrifuge we produced at present, we have GNLW764D-VFD centrifuge, this is mainly for tunneling project which need a huge volume of mud.


The linear motion shale shaker, we have 2 panels, 3 panels, 4 panels and double deck shale shaker for option, all the shaker screens are produced by our own workshop with our brand GN solids control, the composite material shaker screens produced by GN has been approval by many clients in the world for their oil & gas drilling rig.

10 units of shale shakers are shipped to India drilling company this week, they also produced one set of solids control shale shaker tank ready for shipment, including 3 units of same model shale shaker, 1 unit of mud cleaner, 1 unit of vacuum degasser, 1 unit of mud gas separator, 2 units of centrifugal pumps, and necessary mud agitators, mud gun, and 1 unit of mud tank.


GNZS703F-HB shale shaker is one of the best sold model shale shaker, with 3 panel composite material frame shaker screens, we produce OEM shaker screens in GN own shaker screens workshop. Except for the OEM shaker screens, we also produce durable composite material shaker screens for world famous brand shale shaker, like Derrick FLC 500 series, FLC 2000 series, hyperpool, D600, etc, Brandt King Cobra / Venom, VSM300, MI-SWACO Mongoose PT,MD 2/3, FSI, etc. Compared with the steel frame shaker screens, GN made composite material shaker screens with 20% larger effective screen area, the working life is much longer, the storage period is up to 5 years.


The mud cleaner is the combination of desander cone, desilter cone, underflow shale shaker, the treating capacity is different by using different quantity desander cone and desilter cone. GNZJ703F-1S8N with 500gpm capacity with 1ea desander cone and 8ea desilter cone. GNZJ703F-2S12N with 1000gpm treating capacity with 2ea desander cone and 12ea desilter cone. GNZJ703F-3S16N with 1500 gpm treating capacity. The feeding pump for mud cleaner is GN made centrifugal pump , the parts and installation dimension is 100% interchangeable with world famous brand pump.
