Recently GN Company finished production for 8 sets of Mud Recycling Plants, and would arrange final delivery to client’s work site.

GN Mud Recycling Plant is widely used for Bored Piling, TBM, HDD (trenchless), and water well drilling etc., with working capability ranges from 50~3000m3/h.

The Mud Recycling Plant mainly includes Double Mud Shaker, Desander/Desilter, and Centrifugal Pump.
Mud Shaker is used to remove big size of Solids from the Slurry.
Desander/Desilter is used to recollecting Mud for reuse.
Centrifugal Pump is used to pump slurry to Mud Shaker.

GN Mud Recycling Plant Working Procedure as below,

  1. Feeding mud to Shale Shaker from the mud pit. The mud would be feed onto the bottom layer screen of shale shaker (3) through buffer box(2), then the coarse particles would be separated out, while the mud would flow to mud storage tank (4) through the bottom layer screen of shale shaker(3).
  2. The centrifugal pump (5) sucks mud from the mud storage tank (4), and feeds to desander/desilter cone (6) with pressure used for centrifugal separation, the solids/sand would be discharged onto the upper shaker (3) from the outlet nipple of the desander/desilter cone, and fine solid would be separated out. (The screens of Upper and bottom would be different, and the Upper screen’s mesh would be higher)
  3. The mud passed the upper shaker screen would return back to mud storage tank (4), while the clean mud would enter into intermediary tank (7) through desander/desilter cone overflow pipe. The mud in the intermediary tank (7) would go out through outlet pipe (9) or go back to mud storage tank (4) depends on the fluid level in the recycling tank.
  4. In the mud circulation process, there is a fluids level float switch (8) between intermediary tank (7) and mud storage tank (4), it can balance the fluids level in the mud storage tank (4). When mud level is low in the mud storage tank (4), the overflow from the desander would enter into mud storage tank (4) through the intermediary tank (7). When the mud level is too high in the mud storage tank (4), the mud would overflow to the intermediary tank (7) and go out from the outlet pipe (9).

Recently GN Company finished production of 2 units of Drilling Cuttings Management Systems for Xinjiang, China client, and would arrange shipment to client’s work site soon.

The Drilling Cuttings Management System is used for recovering drilling fluids from drilling cuttings as much as possible for reuse, which can save cost and protect environment.

There are two kinds of Drilling Cuttings, Oil based drilling cuttings and Water based drilling cuttings.

For oil based drilling cuttings, GN Company’s System can reduce the oil on the cuttings to 3%-5%.
For water based drilling cuttings, GN Company’s System can reduce moisture content for easy transportation.

This Xinjiang client ordered Oil Based Drilling Cuttings Treatment System. Oil Based Drilling Cuttings Treatment System includes two parts, cuttings drying module and fine solids removing module.

Cuttings Drying Module, its key equipment is Vertical Cuttings Dryer. Its working procedure is feeding Drilling Cuttings into Vertical Cuttings Dryer, then separating oil from cuttings, and passing through the screen opening to the collection groove inside the dryer unit, it is achieved by centrifugal force.
Opening size of the dryer screen is designed of 250, 350 and 500 microns as options for different size cuttings drying. And vertical cuttings dryer is equipped with flushing system and air knife system for cleaning of the mud collection groove and screen, in order to avoid block.

Fine Solids Removing Module, its key equipment is decanter centrifuge. The liquid effluence discharged from the cutting dryer would be pumped into decanter centrifuge for polishing treatment to remove the fine solids in drilling fluids. GN Company can manufacture decanter centrifuge from 9 inch (220mm) ~ 30 inch (760mm), with bowl length and diameter ration up to 4.2, and adjustable G force up to 3000G, for reaching client’s requirement in different projects.

Welcome to contact GN Company for technical specifications and work site reference.

The Offshore Technology Conference (OTC) was founded in 1969, it tends to be the world’s most important exhibition event in Oil Drilling, Development, Production, Environmental Protection, etc, with support of 12 professional industry organizations such as the American Petroleum Institute.

The OTC is the largest oil industry event in the world. It attracted 2,000 exhibitors from 47 countries, and 101,500 visitors from 141 countries around the world in 2018, with a total exhibition area of 697,800 square feet, and exhibition criteria as below,
Petroleum machinery equipment
Oilfield chemicals
Instrumentation,
Technical Services, etc.

GN Solids Control Co., Ltd is a professional manufacturer of separation equipment for 11 years, including solids control equipment and waste management equipment, with supplying equipment to about 76 countries, including Middle East, Canada, Australia, USA, Russia, China, etc.

GN Company attended the OTC exhibition in 2019, and showed Decanter Centrifuge, Sludge/Solids Vacuum Pump, Mud Shaker, Centrifugal Sand Pump, etc.

Decanter Centrifuge can be widely used for Wastewater & Sewage Treatment, Mud/Sludge Dewatering, Oil Sludge Treatment and recovering, etc.

Sludge/Solids Vacuum Pump can be widely used for Solids, Slurry, Powder transferring. 100% pneumatic driven vacuum pump, and can be widely used for different industries, such as mining, construction, and petrochemical.

Welcome to contact GN Company for consulting exact solution for your project, as we can offer One Stop Turnkey Solution for Waste Water Treatment, Solid Liquid Separation, Oil Sludge Treatment, etc.

Recently GN Company finished production of One Unit of Tank Cleaning System for client from South American.

GNTC-30C Automatic Tank Cleaning System is used for cleaning Mud Tank, Oil Tank, Chemical Tank, etc. Its working procedure is to transfer cleaning water to High Pressure Tank Cleaning Machine mounted on the tank, and Integrated Pump would pump waste water back into Tank Cleaning System for filtration & Separation. Then the clean water after treatment would go back to the system for reuse.

Tanking Cleaning System Detailed Procedure is as below,

  1. High Pressure Centrifugal pump (8) pump clean water from Buffer tank (7) and supply to tank cleaning machine(2) to clean the mud tank.
  2. Suction Pump (2) suck dirty wash water from mud tank through the strainer (1) which will filter the coarse solids.
  3. The suction pump (2) will feed dirty water through the static mixer to inclined plate clarifier (5).
  4. The chemical dosing system (3) will supply chemical/flocculants to the static mixer (4) to mix with the dirty water to enhance the separation in the IPC.
  5. The inclined plate clarifier (5) will separate settable solids.
  6. The clean water from IPC (5) will overflow to buffer tank (7).
  7. The buffer tank level control system will control the pumps automatically.
  8. Membrane Pump (6) will take the settable slurry from the IPC (5) to Skip.
