As the crude oil price is lower, many drilling company stop drilling operation and are busy with oily sludge. They want to treat the oily sludge, recover valuable oil, and reduce the impact on the environment. Government in every country also has related regulations on environmental protection.

After about half year communication with different oily sludge client, we promote oily sludge treatment system with shaker, centrifuge, chemical dosing system, and O/W separator. The system includes 4 parts.

Part 1: Mixing tank with shaker and agitators

The shaker on the tank is long deck shale shaker with hot line inlet water/steam, which can help to improve the separation performance of shaker screen. We also advise coarse mesh screen for longer working life, and to avoid sludge stick on the screen.

After separation of shaker, the liquid go down to the mixing tank, the agitator will suspending it. Meanwhile, the chemical will coming from chemical dosing system. Here, the oily sludge will be diluted and have better separation.

Part 2: Chemical dosing system

The chemical dosing system including PAM three tank dosing system, acid tank etc.

Part 3: Centrifuge on telescopic skid

After the mixing tank, the oily sludge will be transfer to centrifuge system. High speed centrifuge can separate the fine solids, discharge down to skips, and the clean liquid go to slant plate clarifier.

We recommend most popular centrifuge model GNLW363 series. The 14inch centrifuge is equivalent to Swaco 518 centrifuge or Derrick DE1000 centrifuges. We have lots of client shift from Swaco/Derrick to GN for centrifuge requirements.

Big bowl big capacity centrifuge is also available, GNLW553 centrifuge is 22inch centrifuge with big volume.

Part 4: slant plate clarifier and O/W separator

Via slant plate clarifier, the solids will be removed. Then, the liquid go to O/W separator, here the liquid will be separated into oil and water. Oil pump to oil tank; water pump to water tank.

If you are in need of solids control equipment, pls contact us freely.

GN can offer various type shaker screens for different model shale shakers. Recently, we have one client from Middle East with 5 land rigs under drilling. He visited our company at the end of last year, and he knows GN very well. At the first, the client need equipment for oily sludge treatment, they failed to win the tender. Next time they need some sets of decanter centrifuges & high G drying shakers, but they are busy with big tender for chemical supply and they lose the centrifuge tender again. We really feel sorry to hear that.

After about half years past, the client needs to buy some screens sample for their rigs working in Oman. And we want to catch this opportunity and start to offer products to them. The client need 20pcs replacement shaker screen for Brandt VENOM shaker (API 70) and 20pcs replacement shaker screen for Brandt VENOM shaker (API 80). We can offer both composite material frame screen and carbon steel frame screen.  In fact, the carbon steel frame screen is not feedback good in some mud condition, even the price of composite material is higher, we recommend client the composite material screen with much better and reliable working performance.

Except for Venom shaker, GN can also offer other different models of replacement shaker screen. For example:

1) Replacement screen for Derrick FLC 2000 shale shakers, pyramid screen and flat screen.

2) Replacement screen for Derrick FLC 500 shale shakers, pyramid screen and flat screen.

3) Replacement screen for Swaco Mongoose, omposite material screen or Carbon steel frame screen, different price, different lifetime and different working performance. We recommend composite as better choice

4) Replacement screen for Brandt king cobra/ Brandt Venom, composite material screen or Carbon steel frame screen, different price, different lifetime and different working performance. We recommend composite as better choice

5) Except for above screens, GN can offer replacement screen for Scomi shakers, FSI shale shakers
