Shale Shaker and Mud Cleaner with Spill proof cover to China Drilling Company

Recently 3 units of GNZS595J shale shaker and 1 unit of GNZJ594J-3S16N mud cleaner with spill proof cover are ready for shipment to China drilling company.

GNZS595J-SHBJ linear motion shale shaker is special designed for offshore drilling rig, which with 5pcs shaker screen panels, dimension 585x1165mm, composite material frame shaker screen, total screen area is 3.4m2, the shaker deck can be adjusted from -1º to +5 º. 2ea of vibration motor drived the shale shaker and produce adjustable G force up to 7.5G. The shaker dimension is 3578 x 2020 x 1439mm. The vibration motor and starter are comply with ATEX explosion proof standard. The aluminum alloy explosion proof starter with protection grade of IP 56 or above. The shaker screens are fixed by ratchet wrench for fast screen replacement. The wear resistant polyurethane rubber strip with good sealing effect and long working life.
The GNZJ594J-3S16N mud cleaner with 1500gpm treating capacity, which consists of 3ea of 10 inch desander cone, 16ea of 4 inch desilter cone and bottom shale shaker. The shaker screen dimension is same with shale shaker 585 x1165mm. The spill proof cover are installed on top of shale shaker to avoid mud spill.

Centrifugal pump is used to feed drilling fluids to desander cone and desilter cone, GN centrifugal pump with hard ductile iron alloy wear resistant material pump casing and impeller, and the bearing is SKF brand for reliable operation.The wide open vane impeller produce lower axial and improve bearing life. All spare parts are interchangeable with international brand centrifugal pump for easy replacement.
Except for linear motion shale shaker and mud cleaner, GN can also produce vacuum degasser, decanter centrifuge, vertical cuttings dryer, mud tank, mud gas separator, mud agitator, mud gun, mixing hopper and various pumps etc. solids control equipments and drilling waste management equipments.

Waste Pit Cleaning Vacuum Pump and Centrifuge for Asia Client

One unit of waste pit cleaning vacuum pump and decanter centrifuge are ready for shipment to Asia client. The working process is that the solids vacuum pump suck the waste sludge from waste pit, and dilute it with water and agitating, then the slurry is feed to decanter centrifuge for dewatering process. The mechanical separation of decanter centrifuge cut point is 2~5 microns, with chemical dosing unit, the separation performance will be improved.

For the waste sludge which with high solids content and high viscosity, it can not be treated by decanter centrifuge directly due to the limit of centrifuge feeding tube. The solids content should be reduced by dilution the sludge by water in the mud mixing tank, if necessary, heating process should be applied to reduce the viscosity.
The vacuum pump main components including tank and base assembly, lifting frame, slurry pipe assembly, suction pipe assy, inlet pipe assy, intake pipe assy, control panel assy, knife gate valve, pneumatic bufferfly valve, air discharge pipe assy, etc. The user will prepare for suction hose and discharge hose according to their suction distance and discharge distance, and also need an air compressor for air supply to solids vacuum pump. For more details of air compressor, pls contact with GN solids control. The user can select automatic motion or manual motion according to the material condition. Under automatic operation mode, the timer of suction and discharge can be set as per experience, the user can adjust it according to mud density, viscosity, suction and discharge distance.

The centrifuge feeding pump is installed on the mud mixing tank and feed the mixed slurry to decanter centrifuge, the progressive cavity pump is normally used as centrifuge feeding pump, for reliable operation and easily adjustment of feed rate, which can be controlled by decanter centrifuge VFD control panel.

Oil Contaminated Soil Washing and Separation Equipment for Middle East Customer

Recently one set of Oil Contaminated Soil Washing and Separation Equipments are ready for shipment to Middle East customer. It is a customized system for Oil Contaminated Soil Washing and Separation, including the modular as below: for more details, pls check with GN solids sales.

  1. Mobile washing module
  2. Solids vacuum pump feeding module: including solids vacuum pump, air compressor module to supply air for the vacuum pump and decanter centrifuge VFD control panel, material suction pipe and discharge pipe, air supply pipe.
  3. Pre-mixing tank 1: including electrical steam generator with water softening equipment, pre-mixing tank with liquid level meter, lightings, electric control system, heating pipeline and tank accessories, mud agitator for chemical mixing and agitating, submersible slurry pump to feed to screening shaker.
  4. Pre-mixing tank 2: including electrical steam generator with water softening equipment, pre-mixing tank with liquid level meter, lightings, electric control system, heating pipeline and tank accessories, mud agitator for chemical mixing and agitating, submersible slurry pump to feed to screening shaker. One pre-mixing tank in use and one pre-mixing tank as back up. Since the electric steam generator can not provide enough steam for heating the oil sludge immediately, the 2 sets of pre-mixing tank design can improve the working efficiency of the Oil Contaminated Soil Washing and Separation system and it can work continuously. Heating process is important to reach the expected treatment result.
  5. Screening module: including shale shaker, pre-mixing tank, mud agitator, decanter centrifuge feeding pump and static mixer.
  6. Chemical dosing module for chemical preparation and mixing
  7. Centrifuge separation modular: including VFD decanter centrifuge, 3 phase disc separator with its feeding pump, flushing unit, solids discharge transfer unit, centrifuge fluids collection tank with mud agitator, buffer oil tank and water tank, and electric control system, lightings, tank accessories.
