Application of Drilling Fluids GN Vacuum Degasser

It is  requisite to install a drilling mud vacuum degasser for their removal from the drilling mud since the invading gases may impact mud properties,  Entrained gas can reduce the hydrostatic head of the mud column and can give rise to catastrophic well control issues.,besides give rise to safety risks and affect the lifespan of some equipment. GN Solids Control manufactures both mud/gas separators and degassers.

Vacuum Degasser 2

Equipment use

The degasser and associated components are designed exclusively for releasing gases from slurries.GNZCQ series vacuum degasser is an new equipment used for processing gas cut dilling fuild developed by our compay which we made reference to various domestic and foreign vacuum degasser .suitable for supporting various types of mud, stabilizing slurry viscosity performance and reducing drilling costs.

product features

Vacuum degasser. Mainly to solve the existing drilling fluid injection device can not be separated in the gas drilling issue. The vacuum degasser can effectively separate the gas drilling, but also to use as a stirrer, a simple structure, in addition to air good effect. Vacuum degassing device using vacuum degassing principle, set filtration, extraction, degassing function as one. Easy operation, high efficiency air filters in addition, is the best means of supporting drug dissolution instrument.


GN degasser can act as a big agiator for the drilling mud, which helps the treatment for desander and desilter.

Oilfield Cuttings Dryers – GN solids control

With the development of request in the field of environment that gives a higher request to drilling field cuttings disposal .We are faced with increasing responsibility to protect the environment in which we operate. GN drilling cuttings management system is used for taking drilling fluids from the drilling cuttings and clean the fluids for resuse. It is to maximize the recycling of drilling fluids, and minimize the drilling waste in order to save cost for operators.

cutting dryer

GNCD Cutting dryer is one of the most important equipment in drilling cuttings management system.Currently GN cutting dryers are used in many drilling oil field all over the world .

Vertical Centrifuge Economics

The vertical cuttings dryer improves overall cost-efficiency, producing reduced amounts of extremely dry cuttings for disposal and recovering valuable fluid for reuse. It is effective with water-, oil- and synthetic-base drilling fluids.

Key Features Of GNCD Vertical Cuttings Dryer

  • More Application:Working for OBM,WBM and SBM.
  • High G Force: Normal 420G @ 900RPM,super high speed with 750G @ 1200RPM.
  • FAG brand premium bearing.
  • The flights on the rotor is hard facing to HRC 65,longer life than our competitors.
  • Special high pressure air knife design to clean the basket screen automatically to avoid the screen blinding especially for high viscosity mud and water based mud.

GN new prduct – solidification unit

Drilling mud contains often-harmful substances (such as High Metal Salts and Organic Polymer, Oil, Acid & Soda materials etc. ) If the wate cuttings was discharged directly without treatment would result in environmental pollution and the vegetation  will be destroyed. A solidification unit is an industrial treatment centre whose aim is to add curing agent and other necessary additive into drilling mud,make it has a good strength and tending to be a stable  solidified form. The harmful substances  will be closed in solidified form and will not leak into the nature. The cured material could be buried directly or used for road paving.


GN solidification unit

The Solidification Unit is a system conbination with screw conveyors and a Mature high shear mixers which has been already in the market for a long time. So it looks like new product but it’s not new product. The solidification unit and thermal desorption unit, as one of the most efficient and economic drilling waste disposal method, has been widely required by drilling waste management companies. solidification techniques are not only used for the treatment of wastes but also for other applications such as the treatment of contaminated sediments, industrial effluents, and for the rehabilitation of polluted sites. GN new developed solidification unit has been shipped to domestic client.

The GN Drill Cuttings Solidification Unit is skid mounted, without any disassembling, can be put into 40ft HQ container. Fully convenient for transportation in all around the world.

How a decanter centrifuge operates

GNLW decanter centrifuge is used to solid – liquid separation.  Separate suspended solids 2-5μm and through the flocculation GNLW decanter centrifuge can separate more of the finer particles.

Structure of Centrifuge

This machine is composed of unit assembly of revolving part, power transmission system,overload release  syatem,base and casing,feed tube,electric control system,etc.

Working Principle of Centrifuge

When drilling mud continuously enters the centrifuge though the feed tube ,it enters the bowl through inlet,the bowl roates in high speed, create a strong centrifugal force, Forcing the finer particles to  overcome the resulting proliferation of sedimentation, also quicken the depositional speed. Different sedimentation coefficient and buoyant density in the mud ot the material will be separated.


Key features of GNLW Decanter Centrifuge (High Configuration)

  • Patent Design with the highest configuration and best material for long and reliable service.
  • Bowl Material from Duplex Stainless Steel 2205 by centrifugal casting.
  • Screw protection: Tungsten Carbide Tiles for longer life and easier replacement.
  • Screw flow distribution port and bowl solids discharge port protected by special ceramic insert.
  • Easily adjustable liquid discharge weir height for flexible application.
  • Bowl assembly supported by tighten belt for protection of bearing in moving.
  • Pressurized EX Proof VFD control cabinet with PLC controlled.
  • Genuine SKF bearing for longer and reliable operation

There are several types of decanter centrifuges and we can also accept customized order. If you have interest in GN’s centrifuges or other equipments,  pls contact us for more information at our website or email us at sales@gnsolidcontrol.com.
