In a complete waste management system in Oil and Gas drilling, no matter it is WBM or OBM or SBM, there are 2 steps of waste management systems, one is standard one, more popular and widely used, and the other is advanced system, for further separation, in case the end user is not satisfied with the separation result, this system comes into use.

1st step separation: Standard Waste Management System:

This is the widely recognized waste management system, always consist of following equipments:

  1. Vertical cuttings dryer for OBM and SBM, or High G Shale shaker for WBM.
  2. High speed decanter centrifuge.
  3. Screw conveyors, or named augers for transporting drilling cuttings.
  4. Necessary tanks for storage.

The standard waste management system is one of GN Solids Control’s best seller systems, because GN is very professional in such solids control systems. Just in this year, in past 10 months, GN has sold out 10 sets of  such waste management systems.

2nd step separation: Advanced Waste Management System.

This system is more called as Dewatering system or Dewatering unit. If the 1st step’s principle is physically separation, the 2nd separation system is combination of both physical and chemical separations.  This system includes such devices:

  1. Flocculation Unit, by adding some chemicals into the mud to be treated just before it enters into centrifuge, we need such a unit. It contains of chemical feeding and mixing devices, and corresponding space like tanks.
  2. Another decanter centrifuge, with high speed, for separation the solids out, such solids are comparably larger particles combined by small particles via chemical treatments.
  3. Such dewatering unit could be located in a 20ft container, including centrifuge or not, depending on customers’ request.

Now because of customers’ requests, GN also has  such systems available. If you need more information about that, we have designs for previous projects for your reference.

Slurry Separation Principle and Functions

Slurry separation principle is complex here .  Firstly , the shale shaker with vibrating strenth could separate the large size of solids particales , Then desander to go on the separte some smaller particales and the processed mud will go into desilter for separation . Since environment becomes more and more important , to meet a function of protect envoironment , slurry separation may goes further important for us .

Sllurry Separation System in China

Totally speacking , slurry separation mud system insist on large treating capacity like 500M3/h, 1000M3/h,2000M3/h or more .  Take a 1000M3/H slurry separation system for example , it contains 5 GNZS83-3 shale shaker , 3 set GNZJ83-3 desander with 3 desander cone , 3 set GNZJ83-3 desilter with 18 desilter cone , 6 sets of centrifugal pump for desander cone & desilter cone .

China GN slurry separation equipments advantages

1.  Top quality with good design of slurry separation equipments.

2. Reasonable price for the equipment

3. Reliable service . Before sales , during sales and after sales service for slurry separation equipments.

PLC Controlled Slurry Separation System

One of our client asked for PLC controlled slurry separation system on mining industry dewatering purification or solids control.

They requested PLC controlled system should for all equipments in the slurry purification system. 

The whole slurry purification system including 2 shale shaker (GNZS 63-3) as first step separation, mud cleaner, decanter centrifuge, screw conveyer. There should be pumps before GNZS63-3 shale shaker. He also asked dewatering screen must be PU. After separating particles bigger than 420microns the solids will be transited by screw conveyor A.

 PLC Controlled slurry separation system brief demand on equipments

Then there must be a tank and agitator then from agitator tank there must be a pump to shale shaker. There are two pumps one is spare. They must be PLC controlled there must be level sensors in the first slurry tank the PLC must adjust the pump speed depend on the incoming slurry if the capacity is not enough PLC must command the second spare pump and it must run all the system must be automatic, there must be level, flow, pressure sensors.

Specical requirements on PLC controlled slurry separation system

They asked 2 pumps for every equipments including Desander, Desilter, Decanter centrifuge. All the pumps should be rubber liner to assure the pump more durable and anti-friction. Because big sand particles are abrasion material 

At first step separation and back second separation there must be screw conveyor for dried sand ,dried silt, etc outputs after slurry separation system processing. 

They emphasized the system must be complete PLC controlled slurry separation system
