Recently one unit of mud mixing tank and 8 sets of mixing pump are shipped to engineering company. The mud mixing tank including 2 round tank with transfer pump, electric control panel with skid, pipelines, valves. The mixing pump and mixing hopper are installed on the skid with pipelines. It is an independent part of mud mixing tank. The mud agitator are installed on top of the mud mixing tank for better agitating and mixing of the chemicals with the drilling fluids.

GN centrifugal pump is interchangeable with world famous brand centrifugal pump, including the bare pump and pump parts. The impeller and pump casing are made of ductile hard iron for better wear resistance. The centrifugal pump can be used as trip pump, mixing pump, super charging pump, transfer pump, feeding pump, etc.
We can design customized mud mixing system according to client’s requirement, normally we design square shape mud tank, the jet mud mixer are connected with mud mixing tank as independent part. Except for mud mixing system, we also produce and design mud recycling system. According to different treating capacity, we have option for 200gpm, 400gpm, 600gpm, 800gpm, 1000gpm mud recycling system. We have 2 phase cleaning, 3 phase cleaning system for mud mixing system, 2 phase cleaning including shale shaker and desilter cone with mud mixing unit, 3 phase cleaning system including shale shaker, desander cone and desilter cone with mud mixing unit.

The mud agitator motor from 3KW to 22KW to suit for different size mud mixing tank, including GNJBQ030-D, GNJBQ055-D, GNJBQ075-DD, GNJBQ110-DD, GNJBQ150-DD, GNJBQ220-DD. The jet mud mixer including mud mixing hopper with different centrifugal pump, we can also install the mud mixing hopper on top of mud tank and the mixing pump installed on the tank skid or the mixing hopper and mixing pump both on the tank skid.

Recently one set of vertical cuttings dryer and decanter centrifuge are ready for shipment to international drilling company. The standard oil based drilling cuttings treatment system including vertical cuttings dryer GNCD930F and decanter centrifuge GNLW363C-VFD, with flushing pump, centrifuge feeding pump, telescopic skid, fluids collection tank, screw conveyor system, waste container, etc.

The F version vertical cuttings dryer is the lastest version vertical cuttings dryer, It is the ideal equipment for oil based drilling waste management system, the working principal is normally as below:
The screw conveyor collect the drilling cuttings from solids control equipments, such as shale shaker, desander, desilter, another screw conveyor which is installed slantly, to transfer the cuttings to vertical cuttings dryer feeding port. The fluids flow to the intermediate tank and the submersible slurry pump or screw pump will transfer the fluids to decanter centrifuge to separate fine solids. The solids discharged from vertical cuttings dryer with oil on the cuttings below 5%, it can be landfilled for disposal or to be sent to further treatment TDU. The fluids treated by decanter centrifuge can be recovered and back to solids control system storage tank, it can be used to prepare for new drilling fluids or sent to third party waste water treatment facility to get clear water.

To treat water based mud drilling waste, we need to use high G drying shaker instead of vertical cuttings dryer, the G force is up to 8.0 G to get drying cuttings, the fluids will be feed to decanter centrifuge, the VFD control panel can control 3 motors frequency and control the bowl speed, screw conveyor speed, pump speed ( to adjust the feeding flow rate). All of the 3 inverters are made from world famous brand electrical components for easy outsourcing locally. We can provide CNEX, ATEX, IEC EX explosion proof standard for option.

Recently 4 sets of vacuum degasser and centrifugal pumps are ready for shipment to Indonesia. The equipments are installed on the mud tank system for oil & gas drilling rig and workover rig. The major solids control equipments including shale shaker, desander, desilter or mud cleaner, vacuum degasser ( or centrifugal degasser), centrifugal pump, decanter centrifuge, mud agitator, mud gun, mud tank, mud gas separator, flare ignition device, mixing hopper, mixing pump, etc.

If the client need a zero discharge system, we will add drilling waste management system to connect with solids control equipments, such as screw conveyor, sludge vacuum pump, vertical cuttings dryer, waste centrifuge, high G drying shaker.
GN vacuum degasser is a self suction degasser unit to separate the gas from the gas cut mud, to protect the next process equipment, like desander desilter feeding pump, and keep the drilling mud balance. The working principal of the vacuum degasser do no need a jet pump, it is self suction unit. The major components of GN vacuum degasser including vacuum tank, electric control panel, water ring vacuum pump, gas water separator, explosion proof motor , the vacuum pump to create negative pressure in the vacuum tank, the mud enter into the rotor shaft, through the suction pipe under the action of atmospheric pressure , the mud spray to the wall and separated to thin layers bubble immersed in the slurry breakup and gas escape.

The centrifugal pump can be widely used as desander feeding pump, desilter feeding pump, trip pump, mixing pump, super charging pump, transfer pump. The impeller and pump casing are made of ductile hard iron for better abrasion resistance. We can also provide the replacement parts for other brand centrifugal pump.
If you need other solids control equipments and mud tank system, pls contact with GN solids sales.

Recently GN solids control shipped one unit of dewatering centrifuge for Municipal Sewage Treatment Company in Southeast Asia. Decanter centrifuge is one of our core equipment,the other core equipments including shale shaker, vertical cuttings dryer, shaker screen, vacuum degasser, mud cleaner, desander, desilter, mud gas separator, mud tank system, centrifugal pump, submersible slurry pump, mud agitator, screw conveyor, etc.

The dewatering centrifuge used for Municipal Sewage Treatment is different with the one used for oil & gas drilling application drilling fluids decanter centrifuge and drilling waste decanter centrifuge, we have sent the professional question list to our customer, once get their answer, we will design a customized solution dewatering centrifuge solution for his project. According to the material solids size, distribution, PH value, composition, and other parameters, we will design with proper angle, screw protection method, screw and bowl material, etc.

For the decanter centrifuge used for oil and gas drilling industry, we have different size decanter centrifuge for option. For drilling fluids decanter centrifuge, normally L/D ratio is 3, for example, GNLW363 series, GNLW453 series, GNLW553 series, according to different explosion proof standard, we will provide different VFD control panel to meet their applications. For drilling waste decanter centrifuge, GNLW363C-VFD is the most popular model decanter centrifuge, we have standard drilling waste management system for oil based mud and water based mud, also we can design drilling cuttings treatment system for both of OBM & WBM.

Dewatering centrifuge worked with chemical dosing unit, we can make customized chemical dosing unit inside 20ft container for convenient operation, also it can be installed on the skid of the dewatering tank. Before using GN centrifuge, we can make lab test with proper chemicals for the customer, the customer can buy it only when the test result is good. For more information of dewatering centrifuge, pls contact with GN solids.
