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.

mud tank

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.

This GNLW363CG decanter centrifuge is the most popular model, we can sell about 200sets each year to overseas market. It is mainly used for solids control, working after mud cleaner to remove the fine solids and reduce the mud weight.  Working together with flocculent unit, the centrifuge can remove much fine solids after coagulation and flocculation.

18inch bowl popular size decanter centrifuge with short bowl for barite recover, GNLW452 centrifuge is mainly used for barite recovery, for solids control.

18inch and 22inch bowl popular size decanter centrifuge with longer bowl for solids control and fast drilling mud treatment

If you are from oil drilling field, we recommend you GNLW363CG fixed speed decanter centrifuge or GNLW363CG-VFD variable speed decanter centrifuge for flexible use. This is also the most popular model centrifuge, we have stock in warehouse for fast delivery. We can also offer DNV certificate if the centrifuge will be used for offshore and need helicopter lifting transportation.

Shale shaker is the first stage for solids control system, removing big particles by separation shaker screen. We have different model shale shaker for option, from 2 panel shaker, 3 panel shaker to 4 panel shaker. Different model shale shaker is suitable for different field application. Eg. The 2 panel mini shaker is mostly used for small drill rigs, like diamond drilling, core drilling, mining, water well drilling etc. The 4 panel shale shaker is mostly used for oil drilling rigs with higher horse power. 4 panel shaker is also the max. in size which is suitable for big mud cleaning systems.

Recently, we ship 2 sets shale shaker with 60pcs shaker screen to one domestic client. The clients require 2 sets 3 panel shaker for HDD project; replace the old shakers in the mud system. We have assembly parts for shaker and only 15 days after receiving the deposit, we deliver the cargo to clients by truck. After update the mud system with new shaker, the mud system now is working perfectly with the drill rigs to conduct the HDD projects.

The client bought this agitator is GN old client who already bought 2 sets 500gpm compact mud system for HDD drilling. They are really happy about the high quality of mud system and the premium working performance of the mud system. The 500gpm mud system is equipped with 4 panel shale shaker and 4 panel mud cleaner. The shaker screen is composite material shaker screen with much better working performance, longer lifetime and less maintenance. Actually, this client also bought one sets 200gpm mud system in year of 2013 for Dubai project.


2) 2 sets shale shaker for Middle East client

The shale shaker is to update the mud system the client already have for over 2 years. The client buy 2 sets new shale shaker to update their old mud system and this is relative lower cost to ongoing the new project. Because of the down market, many clients want to deduct budget, save cost and do more project. We recommend client to renew the mud system with new equipment, new shaker, new centrifugal pump, new mud cleaner and new agitator. Generally, the mud tanks can last longer time if the daily maintenance is doing each time after use.
