GN Solids Control designs and manufactures different sizes of liquid sludge plants according to your needs. We can design and build as many vertical tanks, rectangular tanks, round tanks, etc. depending on your space and requirements.

 

The Liquid Mud Plant is installed for one main purpose and that is to maintain good properties of the drilling mud in the wellbore as much as possible. Within each drilling fluid supply base, you can usually find which “Mud” companies are working offshore from this base, as they are represented in the form of a Liquid Mud Plant. This liquid mud plant is used to handle (mix, dilute, treat, adjust) various drilling fluids to be used in the wells supported by this supply base. You can also find expanded drilling waste management (DWM) or solids control processing for drilling mud here, usually in the form of decanter centrifuges used to treat used mud that has been recharged at the supply base. . Offshore supply vessels are used to transport any drilling or completion fluids to and from the Slurry Plant that cannot be mixed or treated on-site.

Features of screw press dehydrator machine:

• The main body of the screw press sludge dewatering machine is a filtration device composed of a fixed ring and a movable ring, in which the screw axis runs. The front section is for concentration and the rear section for dehydration.
• The filtrate gap formed between the fixed ring and the moving ring of the dewatering screw press and the pitch of the screw shaft gradually decreased from the concentrating section to the dewatering section.
• The rotation of the screw press shaft not only pushes the sludge from the concentration section to the dewatering section but also continuously drives the moving ring to clean the filter space and prevent clogging.
• After gravity concentration in the concentration section, the sludge is transported to the dewatering section. In the process of advancing, with the gradual decrease of the filtrate space and the pitch of the screw, and the locking effect of the backpressure plate, the large internal pressure is generated; leader, the volume is constantly reduced, in order to achieve the purpose of complete dehydration.
• The dewatering screw press is generally applicable to sludge concentration of 2000mg/L-50000mg/L

The GN Shale Shakers are widely used for solids control, they are equipment that allows drilling cuttings to be removed from the drilling fluid and this entire process is done while circulating and drilling. In recent years NG technology has been improving, many different designs have come onto the market, and research on the best design is constantly progressing as solids control is vital to keeping down the costs associated with drilling fluid.

The primary principle of these Shale Shakers is to shake or vibrate the meshes with the drilling cuttings, with the motors vibrating it generates a centrifugal force that makes the equipment shake in Linear or Elliptical mode causing the drilling fluid to flow through Shakers Screen and return the drilling fluids or to another stage in the mud system, with this principle it separates the drilling cuttings or commonly called fluid solids from the drilling fluid so that it can be recirculated back to the well.

 

GN Solids Control is constantly producing Shale Shakers to serve the world market with these solids separation equipment.

Description

The mud dewatering unit is an excellent solution that could provide the separation processing for the ultra-fine solids’ particles, always less than 5 microns, in the water base drilling mud.

Why Need a Mud Dewatering Unit?

As it is known during a normal drilling mud solids control processing, the primary equipment like shale shaker, desander, Desilter, even the decanter centrifuge can only remove the solids larger than 5 microns. For the solids less than 5 microns, it is difficult to separate out by using the regular mechanical method. After several times for using and recycling the drilling mud, the ultra-fine solids will build up to a large content in the drilling mud, which will disrupt the mud property. In order to maintain the mud property at a proper level, the operator needs to add water into the mud for dilution which will cost a large quantity of water. Here is the point, the mud dewatering unit is used to remove the ultra-fine solids from the drilling mud to prevent the built-up. Thus, great would be saved.

GN’s mud dewatering unit is designed to be fabricated inside a container. According to the equipment quantity involved in the system, the 20 ft or 40 ft container would be optionally chosen. After being treated by GN’s dewatering unit, the drilling mud could be treated as clean water for discharge or reuse.

The purpose of the mud system is to separate the solids from the drilling fluids, although it is true that the Shale Shakers make the equipment vibrate with their motors, the Screen Shakers play an extremely important role when screening the drilling fluids; GN Solids control has managed to develop with high-quality standards with an International format following the norms imposed by the US market, API RP13C or ISO 13501, allowing the manufacture and massive sale of our meshes to the world market, little by little it has been consolidating as a successful option and benefited by the technology offered in its final product.

The GN Shaker Screen was tested by an independent third-party USA company according to API RP 13C(I-SO13501).

(Please contact GN for a detailed API RP13C testing report.)

Features of GN Shaker Screens:

• Automatic Robot Welding of the steel frame to have better quality and consistency.
• High-quality pretension screen for long operation life.
• Four side tension of mesh during the heat press to minimize the gap between the top screen and support screens, in a result extending the screen life. Our competitors normally do not use any tension for heat press.
• GN 3-layer wire meshes for API 60 and above for longer screen life, our competitors normally use 3 layers only for API 120 and above.
• GN wire mesh supplier is an internationally famous brand.
• The steel frame screen is repairable to save cost.
• GN comprehensive line steel frame screen for GN shakers, MI-Swaco Mongoose, Nov Brandt Cobra, Venom,
• VSM-300, FSI screen, Derrick 2000, 500. And we can customize any screen dimension.

ASTM Mesh and API Cut Point:

• ASTM is short for The American Society for Testing and Materials, ASTM E11:01 mesh equals to ISO 3310- 1:2000 mesh. This method determines the cut point of single-layer ASTM screen mesh size. For shaker screen mesh, normally means the surface screen mesh size. Whilst the shaker screen is usually a composition of 2 or 3 layers, the cut point of the first layer’s mesh is not equal to the final shaker screen cut point.
• API is short for American Petroleum Institute, “API Number” is determined by API RP13C or ISO13501, the cut point is related to the combined 3-layer wire mesh test result. So before ordering, GN will need an API number, or the cut point, to define a more proper shaker screen configuration.
