As a professional drilling fluids shale shaker manufacturer in China, GN solids control developed offshore ViST vacuum shale shaker and shipped to offshore project this week.

Why use GN ViST vacuum shale shaker?
The user already installed solids control system at site, why they should use GN ViST vacuum shale shaker? GN ViST vacuum shale shaker is GN shale shaker with a vacuum suction hopper installed under the last shaker screen. It has a combination function of solids control shale shaker and high G drying shaker, and save the space to install the high G drying shaker, especially for the offshore drilling rig when there is no enough room to install drilling waste management equipments, The ViST vacuum unit solved the problem.

By using GN ViST vacuum unit, the drilling fluids recycling efficiency will be increased by 30~ 50%, it reduced a lot the discharged drilling cuttings, then reduce the cost to transport, treat and disposal the drilling waste. It reduce the hazardous drilling waste influence to environment, and do not waste electricity power at site, it can use the same air compressor with rig.

As a professional waste water treatment decanter centrifuge manufacturer in China, GN solids control can produce decanter centrifuge for many different applications, including waste water treatment, mining tailings treatment, dredging slurry separation system, drilling fluids cleaning, drilling waste treatment system, oil sludge separation system, dewatering unit, etc.we shipped several unit of decanter centrifuge to Russia for waste water treatment, the model is GNLW363C-VFD.

The features of GNLW363C-VFD decanter centrifuge:
1) Bowl material is duplex stainless steel 2304 by centrifugal casting, the anti-corrosion is better than SS316L. The screw material is made of SS304 by heat treatment up to 1000 degree, the screw opening allow for better performance and bigger treating capacity. The bowl collection box is made of stainless steel for corrosion resistance.
2) The bearing is SKF brand to ensure the reliable performance

3) The centrifuge will be installed on top of the telescopic skid or on top of mud tank, by working together with dewatering unit.
Except for GNLW363C-VFD, we also have 14 inch bowl decanter centrifuge for high speed up to 3900 rpm GNLW363CG and longer bowl length/ diameter ratio decanter centrifuge GNLW364C-VFD, it can be applied for high viscosity fluids separation. We will send a question list to get exact information of client’s requirement, then provide a customized decanter centrifuge solution for his project. We will have customized design for special fluids solids separation, for example, higher clearance water, drier separated solids.

This week GN solids control shipped 56 units of mud agitator and 3 units of vacuum pumps shipped to China client. Mud agitator is one of the major equipments for mud tank system, it also works together with mud gun.

There are 2 types mud agitators, horizontal and vertical installed mud agitator. Most of the mud agitator is horizontal type mud agitator for oil and gas drilling mud tank system, there are also 2 types horizontal mud agitator, one is direct connection type mud agitator, the gear box and explosion proof motor is installed directly; the other one is coupling connection type mud agitator, the gear box and explosion proof motor is installed through the coupler on the skid. The mud agitator is installed on the mud tank for agitating the drilling mud and prevent it from silting.

The vacuum pump is used to transfer the drilling cuttings, solids waste, oil sludge, dredging slurry, hazardous waste, oil contaminated soils, etc waste. The vacuum pump is operated by air, no need electricity power. There are automatically operation and manually operation for option, the user need to get the vacuum pump ready before commissioning.
We have 10 m3/h, 20 m3/h, 40m3/h flow rate vacuum pump for option, the user can choose different model vacuum pump based on the required flow rate, the max solids size limit will depends on the pump model. Screw conveyor is another method for drilling cuttings transfer system, if the fluids content is very high, the vacuum pump is more suitable for such drilling waste.

Recently one set of oil based drilling cuttings treatment system is shipped to CNPC project , the technical specs are as below:
1) High G force vertical cuttings dryer: Vertical cuttings dryer is the ideal equipments to separate oil from oil based drilling cuttings, the result is the oil on the cuttings below 5%. The flushing pump for the vertical cuttings dryer is Germany Netzsch brand screw pump, the client can choose to use their own pump if necessary.

2) High speed decanter centrifuge to separate the fine solids from the fluids recovery from the vertical cuttings dryer fluids discharge port. The centrifuge feeding pump is Germany Netzsch brand screw pump for reliable feeding.

3) Catching tank to collect the fluids discharged from vertical cuttings dryer and decanter centrifuge, the tank divided into 2 compartments, each compartment with one mud agitator to prevent the soils from deposition.

Features of GN high speed decanter centrifuge:
1) Whole screw is made of stainless steel material, heat treatment to 1000 degree for better strength, the screw opening allows larger treating capacity and better separation performance
2) The collection box is made of stainless steel, the bowl is all made of deplex stainless steel 2205 by centrifugal casting.

Recently GN solids control shipped one set of high configuration solids control system for workover rig to Australia. This is not the first unit mud tank system working in Australia, we have over 30 sets of mud recycling system to Australia, we have experience to manufacture solids control system which can meet the Australia explosion proof and safety standard.

The technical specifications of this solids control system is as below:
1) 2 units of shale shaker installed on the shaker tank for cleaning the drilling fluids, with mud agitator, mud gun, etc accessories, we have 3 panel shale shaker and 4 panel shale shaker for option, all installed composite material shaker screens.
2) 2 units of mixing pump, 1 units of venturi hopper installed on the mixing tank for adding chemicals to prepare for the new drilling fluids, with mud agitator, mud gun, walkway, handrails, stairs, valves, fittings, flexible hose, connection pipeline, etc. The clean gate is with high position gate valve type for convenient cleaning of each compartment, we will try to design the clean gate in the middle of each compartment.

3) The painting and coatings are comply with Australia safety standard, the the tank top surface is fixed with high strength glass fiber reinforced plastics for better UV protection as per client’s request.
As a professional manufacturer of solids control equipments and drilling waste management equipments in China, GN solids control can produce shale shaker, mud cleaner, desander, desilter, decanter centrifuge, vacuum degasser, mud gas separator, mud agitator, mud gun, mud tank, vertical cuttings dryer, screw conveyor, screw pump, shaker screens, etc equipments.
