mud gas separator

Last week, after months of hard work of all GN staff, 70 containers of solids control equipments from GN Solids Control sailed to Middle East. This is a land mark of not only GN’s company memorandum, but also a breakthrough of China branded solids control equipments and drilling waste management equipment. This order is working for oil service in middle east and work in tough conditions of temperature above 55 degrees centigrade.

Those equipments are of high quality material and per clients’ requests, they are of ATEX Zone 1 standard and with DNV lifting.

GN VFD controlled decanter centrifuges are always popular among the clients and countries in middle east and other high temperature conditions.

For the centrifuge main body, the high configuration GNLW series decanter centrifuges share the same features like:

  1. best bowl material SS2205 by centrifugal casting and such is the highest standard material for oil and gas decanter centrifuges. Many European and USA brands use this kind of material for bowl material.
  2. SKF bearings for stable performance and longer service life. And during transportation, GN has special and gentle solutions for protecting the bearings from being damaged on the rough road.
  3. tungsten carbide tiles for impeller protection and special ceramic material for solids discharge ports.

And many other features are applied.

About the VFD control panel, GN has both flame proof VFD control panel and positive pressurized VFD control panel with PLC smart touching screen. The positive pressurized control panel has the self cooling system, and it is more suitable than the flame proof ones in high temperature condition. All the electric components are of international famous brands like Siemens, Schneider and ABB. For this order, because they are of ATEX Ex, some brands and standards are even higher than usual.

Centrifuges are greatly used in solids
control and drilling waste management systems in oil and
gas drilling industry, because it could separate out directly or together with
chemicals the fine and extra fine solid particles from the liquid at a high
rotating speed of the bowl. In a solids control system, it is always used after
the desilter and in waste management systems for drilling cuttings, it is used
after the high G dryer shaker or vertical cuttings dryer. When using together
with chemicals like dewatering, it is used after the dewatering unit.

Normally, what equipment is used to feed
the decanter
centrifuges
? Although in theory, the centrifugal pump could be used to feed
the decanter centrifuges just as the centrifugal pumps are served for the desander and desilter,
the centrifugal pump is not an ideal solution. Mostly practical options are submersible
slurry pump and screw pump.

1. submersible slurry pump: just as its
name, the submersible slurry pump has some part of the body underneath the
liquid, and it is vertically installed on the tank for feeding the decanter
centrifuge. In most cases, it is used for fixed speed decanter centrifuge. comparing
with a screw pump, it occupies less space for install and the price of
submersible slurry pump is lower than a screw pump, because the material and
producing technology is less complicated than screw pumps.

2. screw pump, also called mono pump in
practical uses, the most important parts of the screw pump are stator and
rotator, by rotating of the rotator, the transported media is conveyed evenly
and at a stable speed to the decanter centrifuge. Frankly speaking, this is
more suitable as the feeding pump of decanter centrifuges. GN always match its
decanter centrifuge with Netsch pump, which is a German brand, and the liquid
touching parts are all made of SS316L.

GN keeps research and develop the best
technology to manufacture top quality equipment ,such as Mud Gas Separator,
mud agitator, Vacuum
Degasser
and other solids control equipment for our clients,

GN Solids Control has provided many sets of mud
recycling systems
for various mud control area or industries, such as HDD,
TBM Drilling, CBM Drilling, Bored Pile Drilling etc. Just in this May, GN
Solids Control just provided one set of 500GPM mud system in HDD area.
GNMS-500GL is one of the most cost-effective mud recycling systems and widely
used in the global world. GN also has some other mud systems to meet treating
capacity demands, such as 200GPM, 1000GPM. Some other customized mud recycling
systems can also be provided based on customers’ working conditions. 

This GNMS-500GL mud system has been successfully working for more than 3
project s during the past 5 months. At the beginning, GN sent service engineers
for installation and debugging. For clients need training or commissioning
service, GN can also send out their engineers.
GNMS-500GL mud system includes the following main equipments: shale shaker, mud cleaner, mud
hopper, mud tank.
Some auxiliary equipment such as mud agitators, mud
mixing hoppers, centrifugal pumps are also included in this system.
GN mud recycling systems are very popular in many regions or countries, such as
South America, Africa, Middle East, Australia, India, Korean, Burma and
Indonesia etc.
With the fast development of GN Solids Control, GN mud systems are exported to
over 60 countries. Most of those GN mud systems are being used in abroad,
nearly 70% are exported from China. And with the establishment of GN Solids
America LLC, GN solids control equipments and drilling
waste management systems
are widely known by North American companies.
GN Solids Control also provides decanter centrifuge, cuttings dryer, Hi-G
shaker for WBM, OBM or SBM treating. At the beginning of 2015, GN also provided
some sets of solidification unit to treat the drilling cuttings separated after
cutting dryer, centrifuge. In the near future, GN will launch a newly upgrade
cutting dryer to treat the WBM especially.
