The business of today’s GN has been divided mainly into 2 scopes, one is the normal drilling mud recycling, and the other is the waste management including the waste coming from petroleum related and other separation industries. This blog is mainly talking on the drilling mud recycling system that used in non oil drilling industry.
In oil drilling, the drilling depth and safety regulation request large drilling mud storage and more solids control equipment. Thus, the mud recycling system is always equipped with degasser unit and large volume mud tanks.

HDD Mud Recycling System

Comparing with the mud recycling for oil industry, the unit for non oil drilling is more compact and less equipment needed.

  • Trenchless/No Dig HDD project – The mud recycling system used in this type drilling is matching with a No dig rig. In some project for long distance pipeline and cables laying underground, it is inconvenient to dig an open groove on the ground as that will interrupt the normal traffic. The trenchless is an ideal choice. The mud recycling system for this project is always consisting of 3 stages separation as shale shaker unit, de-sanding and de-silting cyclone.
  • Piling is the main method to install the bridge supporting pillar. A de-sanding unit with a small tank would be enough to remove out the coarse solids from the drilling fluids. The de-sanding unit is a composition of de-sander cyclone and shaker unit that can separate out the solids with size of 40-70 microns. Piling does not request very clean mud; less equipment involved makes the recycling unit for piling is very compact.
  • GN also can manufacture the mud recycling system for tunneling project. For micron tunneling, GN has model available with capacity of 120m3/h, 240m3/h and 500m3/h. For large flow rate request, GN has the mud plant GNMS -3600M with treating capacity of 3600m3/H.

Besides, GN’s mud recycling system can also be used in water well drilling, coal bed methane exploration, dredge slurry separation and the mining flushing waster cleaning process.

GN’s decanter centrifuges are 2 phase type and mostly used in oilfield for drilling fluids fine solid particle separation and waste management as GN is known as a China leading professional manufacturer for solids control equipment for oil & gas industry. However, according to the working principle, the centrifuge should be able to be used in some other industry for liquid and solids separation just like the dredging slurry separation and construction site solids removal.
GN ever sent one solids removal system including shale shaker and decanter centrifuge to London for the construction project there. On the construction site, the worker may use water to wet or mix some construction material. Nowadays, most of the office building has parking area at the ground floor of the building. When the beginning of building, the workers will operate the rotating drilling machine to drill some holes on the ground for piling. This type of drilling will also need water for cooling down the drill bit and take out the drilling cuttings from bottom of the drilling hole.

GN-SOLIDS-REMOVAL-LONDON

Solids Removal Unit

GN’s solids removal system is used to separate the solids and liquid. On construction site, it will be used to remove the stone and other large size solid particles from the water. The unit sent to GN’s customer in London was a 2 phase solids control system. The configurations are as below:
1 unit shale shaker with 3-panel screens for primary solids control could remove most of the large size solid particles. The solid particles on construction site would be various from sand, stone, leaves and waste cans. The shaker could remove almost all the coarse particles by using the wire mesh screens.
1 unit decanter centrifuge with speed up to 3200 rpm is used for fine solids separation. GN’s centrifuge is made of excellent material on bowl and screw propeller for long lifetime and easy maintenance.
1 mud storage tank is divided into two compartments for sand trap under the shale shaker and clean liquid collection under the centrifuge. 2 pumps are installed on the tank skid. One of the pump transfers the slurry from sand trap compartment to the centrifuge, another one is used to transfer the liquid out from the tank for reusing.
GN’s mud tank system is with the CE certificate thus the clients from Europe could use GN’s mud system freely without worrying about the compliance. For any request, welcome contact GN for more information.

As per the feedback from the customers who are engaging in the pilling business, GN designed and perfect the economic mud recycling system specially for the drilling mud cleaning application in piling project. On the consideration of limited location area of the piling project job site, GN’s piling mud recycling system is designed with a very compact structure but with full functions for drilling mud recycling.

De-sanding Unit

Below is the standard configuration of piling mud recycling system with treating capacity of 500GPM.
Model: GNMS500-D
Flow Rate: 500 gallons per minute
Cyclone Specs.: 1 pc 10” de-sanding cyclone made from 100% polyurethane
Screen Specs.: Shale shaker with up and down 2 layers screen with total screen area of 2.23m2
Feeding Pump: Mechanical seal type centrifuge pump of 50 HP used to feed mud to the de-sanding cyclone
Cut Point: Solids Removable down to 40 microns
Catching Tank: Under located catching tank for mud storage. The tank is equipped with lighting system and ladders for easy operation.
Electrical Control System: Explosion, water, and dusty proof electrical control panel with SIEMENS or Schneider components

GN also has the model of GNMS200-D and GNMS1000-D available and the treating capacity is separately 200GPM and 1000 GPM.
The advantage of this type mud recycling system is cost competitive. By connecting with storage tank and mud mixing hopper, this de-sanding unit could also be used in other kind of project like the small horizontal directional drilling, micro tunneling and water well drilling.

Economic Mud Recycling Unit Layout

GN recommends the layout of this economic mud recycling system:
1) Mud Pit
2) Submersible Slurry Pump
3) Mud Recycling System
4) Storage Tank
5) Outlet Pipe
6) Jet Mud Mixer.
GN Solids Control also offers submersible slurry pump, mud storage tank, as well as jet mud mixer per request.
GN is now on promoting this type economic mud recycling system, for more information, you may sent inquiry to sales@gnsolidscontrol.com

Desanding plants are also a very important part of liquid solid separation, and GN 50 can also applicant in other fields, like mining industry, well drilling, deep drilling and so on.

The main components of all desanding plants are: Coarse screen for intercepting stones larger than 5 mm;  Storage tank of the coarse screen;  Cyclone with cyclone feeder pump for removing fine particles from the suspension; Dewatering screens for abstracting further water from the solids dis-charged by the cyclone. GN 50 use high efficiency linear motion shale shaker, with OLI brand motor, high quality centrifugal pump.
