Recently GN solids control shipped 4 units of jet mud mixer and 2 sets of vertical cuttings dryer to China drilling company.

The jet mud mixer is a combination of mud mixing hopper and mixing pump with pipelines, valves, control panel all in one skid as a complete mud mixing package, the user can put in on the flat ground and connect it with the existing mud tank by flexible hose conveniently. The venturi hopper working pressure is 0.25 ~ 0.4 Mpa, it can be equipped with proper mixing pump for different mixing capacity, including 320m3/h, 272 m3/h, 200 m3/h, 150m3/h, 120 m3/h, 90 m3/h, 65 m3/h, 55m3/h, 45 m3/h, for client’s different mixing capacity requirement, we will select proper model.
The mixing hopper can be installed on the tank top and the mixing pump installed on the tank skid for better mixing performance. The mixing hopper and mixing pump can be both installed on the tank skid.
The vertical cuttings dryer is ideal equipment for oil based drilling waste treatment system, it works together with decanter centrifuge. GNCD930 vertical cuttings dryer is the most popular model among our drilling waste management equipments. The screw conveyor transfer the drilling waste to vertical cuttings dryer, the discharged solids from vertical cuttings dryer with OOC below 5%, it can be landfilled or for construction industry. If the disposal limit in the client’s country is below 1%, further treatment like TDU should be applied to meet client’s requirement.

The discharged fluids will flow to the intermediate tank, the decanter centrifuge feeding pump transfer the fluids to decanter centrifuge to separate fine solids, the discharged fluids from decanter centrifuge can be reused to prepare for new drilling fluids with mixing hopper.
If you need solids control equipments and drilling waste management equipments, pls contact with GN solids engineer.

Recently GN solids control shipped one batch of decanter centrifuge with sludge transfer pump for environmental engineering company abroad, this is for non-oil & gas industry application. The equipments list including:

2 units of 9 inch bowl mini decanter centrifuges, we have 3 models for the 9 inch bowl decanter centrifuge, GNLW223D & GNLW223D-VFD, GNLW224D & GNLW224D-VFD, GNLW224EP series, the 9 inch mini centrifuge can be used for core drilling waste water treatment to recovery more water and for environmental protection. The GNLW224EP series decanter centrifuge can be widely used for different waste water treatment, we can provide customized design to archive better treatment result. The difference of these models are bowl length, back drive motor and differential speed. The longer time of the waste water stay in the clarifier section, the better of the discharged water treatment result.

Centrifugal pump, which can be used as sludge transfer pump, charging pump, feeding pump and trip pump, all the parts are interchangeable with world famous brand centrifugal pump, the pump casing and impeller are made of hard ductile iron alloy for better abrasion resistance.

Sludge vacuum pump can be used as transfer pump of different materials, like drilling fluids, drilling cuttings, animal waste, industrial waste, oil contaminated soils, sand, oil sludge, hazardous waste and others. It is 100% air operated pump without electricity power consumption, but it requires air compressor for air supply and provide pressure. We have 3 models of vacuum pump with 10m3/h 20m3/h and 40m3/h nominal flow rate for option, the actual flow rate will depends on the material density, viscosity and the suction/discharge distance & depth. The small model is movable design with wheels and the bigger model frame is fixed.
If you need a solution for waste water treatment solution, pls contact with GN solids control freely.

Recently one set of liquid mud plant are ready for shipment to South America. It is one of the three components of the complete liquid mud plant for this client, the client take this part as first phase project, it consists of mud mixing tank and storage tanks.

The mud mixing system is a square tank with 400bbl capacity, two each of special designed dust free mixing hopper are vertical installed on the mud tank and drived by 2 units of slurry pump for mud mixing. 2 units of mud agitator are agitating the mud to prevent it from precipitation in the tank bottom, the mud gun are installed as mixing and transfer of mud which is drived by centrifugal pump. The tank accessories including hand rails, pipeline, valves, walkway, stairs, and one unit of operation table, there is a stair to walk on and easily take the dry bulk chemicals and put it on the mixing hopper.

The mud storage system including 14 units of cylinder tanks in 2 rows and connected by pipelines and controlled by valves, the gun line outside the cylinder tank to transfer the mud flexible. The mechanical liquid level meter outside the vertical tanks can easily check the mud level by the operator.
2 units of centrifugal pumps are installed on both end of the storage system and connected by pipelines as transfer pump, they can transfer the mud from any storage tank to mixing tank, and transfer mud from mixing tank after mixing to any storage tank. All the gate valves, bufferfly valves, and all the rubber parts in the system are all oil resistant material for longer working life. The system color is customized blue color, we can also paint with client’s LOGO if required.
