“GE, an industrial company, but also a digital company”. Some people may have watched this commercial on American’s main media, like CNN or NBC and we may wonder what does that mean? The answer is it represents the future trend-digital and automation.

As we all know, GE is the conglomerate in many industries, such as energy, electric appliances, aerospace and so on. So its action and strategy will represent the future of the industry. Recently GE just opened its new main office nearly San Jose and recruited a lot of engineers from Google, Apple, Microsoft with background of electrical engineer to develop its own system  called “Predix”, which is the world’s first and only cloud-based operating system for industry. GE plans to make “Preix” as the industry standard similar to the position of Microsoft Windows system in the PC industry. It will realize the digitalization and automation of the industry, including the oil and gas industry. One example for this trend is on June 14,2016, GE and Technip signed memorandum of understanding to explore digital solutions for new LNG projects. LNG will have great potential for growth as the world’s demand rises. So this prosperous area will be co-developed by the combination of strength of GE and Technip. GE will provide it reliable equipment solutions for the global LNG facilities, through sensors, advanced analytics and diagnostic expertise. Technip will provide unique expertise in EPC for LNG projects.


The future of the oil and gas industry will be more efficient and powerful, which will be realized by digital and automation and will optimize the equipment and operation to improve the productivity and cost-efficiencies.

As the crucial part of the mud cleaning system of the oil and gas industry, solid control system will also inevitably follow the trend of automation and digital, including its shale shaker, desander, desilter, mud cleaner, decanter centrifuge, mud agitator, cuttings dryer  and some other equipment and parts. GN solids control can manufacture the most advanced solid control equipment in the industry, such as the VFD controlled equipment which can realize the automation and digital.

GN Solids Control is one of the top Solids Control Equipments manufacturer in the world. We manufacture a complete line of Solids Control Equipments, Such as  Shale Shaker, Mud Cleaner, Degasser,Centrifugal Pump, Decanter Centrifuge,Agitator,etc.  As the development of GN in the past 5 years, Now GN also can provides customized drilling fluid dewatering systems designed to reduce volumes of waste and reducing long term liabilities.dewatering is the process of injecting coagulants or flocculating chemicals into the mud entering a large clarifying centrifuge.

In a minimal discharge, environmentally sensitive area, this mud cannot simply be dumped in a sump and forgotten about.This is where mud dewatering becomes necessary. Also during cement displacements and at the end of the well, dewatering is used when the mud needs to be disposed of.

Dewatering Process:

Drilling Fluid Dewatering System

Drilling Fluid Dewatering System

1) Mud from the active system is pumped into either a separate mud tank or directly into an injection manifold. This mud is tested by the Solids Control engineer immediately prior to processing. Through a series of standard tests, the operator determines the approximate amount and type of chemicals to give an optimum flocculation/ stabilization of the mud.

2)The injection manifold has a series of injection ports and internal static mixers. The calculated amounts of chemicals are metered into the ports with chemical injection pumps. These pumps have variable controls to continuously adjust the amount of chemical injected.
3)The mud which added coagulant and flocculant then goes to a high-speed, high G-force Decanter centrifuge. The Decanter centrifuge separates the flocculated solids from the fluid.

4)The quality control tank allows the unit operator to monitor the effluent from the centrifuge returned to the active mud or storage system. The operator can then make further adjustments to the chemicals and equipment to ensure optimum dewatering. A bypass allows the operator to recirculate the centrifuge effluent if necessary.

5)The neutralizing tank may be used to store dewatered fluid and to make final treatments to the processed fluid, such as pH adjustments, before the fluid is recycled as makeup or dilution water. This tank is partitioned and can be used for prehydrating bentonite, for mixing chemicals, or for storing excess mud.

The heart of GN’s dewatering systems are the polymer conditioning manifolds and high-speed decanter centrifuge. Each manifold is carefully engineered to provide optimum polymer hydration. For more information of GN’s Dewatering System, Please feel free to consult with GN’s engineer

5 SUCTION HOUSING FLANGE can be rotated to any of four positions in 90o increments.

6 CONNECTING ROD is extra long for extremely low angularity, resulting in less loading on the universal joint which provides longer joint life. (Back to Illustration)

7 TWO CLEAN OUT PORTS come standard on larger pumps with a cast iron housing. Clean out ports are available on pumps with other metallurgy as an option.

8 DRAIN PLUG is located at the lowest point on the suction housing. This allows for the housing to be completely drained.

9 UNIVERSAL JOINTS are SM pin-type or double sealed joints on certain sizes. Sealed pivot-type joints available on larger pumps.

10 ENLARGED SUCTION HOUSING at the rotor end for non-restricted flow of heavy materials.

11 THRU-BOLT CONSTRUCTION for easier maintenance, stator removal/installation.

12 STATORS are available in a wide range of materials including natural or synthetic rubbers, cast iron, stainless steel, a wide variety of rigid plastics, and others. The inlet side of the stator is chamfered to allow for unobstructed uniform feeding to the rotor and stator elements. Gaskets are an integral part of the stator on non-rigid materials.

13 ROTORS are available in a broad range of materials including hardened tool steel, chrome plated hardened tool steel, stainless steel and others with optional chrome plating. NEMO CERATEC? is also available in various sizes.
