The negative affect from the oil crash has spread to many industries related including the HDD projects. But as the leading and well known HDD mud system manufacturer, GN Solids Control still have orders and repeated orders from the old clients.
By end of last year, GN Solids Control has just delivered a high configuration of mud systems for a HDD project. Now the end user is laying a repeated order for the same mud system, and it is scheduled to be ready early after Chinese New Year.
Not only for the oversea market, but in domestic China, 500GPM mud recycling system is still the most popular option for HDD projects. CPP, the largest HDD contract in China, purchase around 10 sets of mud recycling systems from GN Solids Control each year, and most of those are of 500GPM capacity.

500GPM Mud System

Main Equipments for Standard Configuration GNMS 500 Mud System:
Shale shaker: GNZS703E-DZ, 1 set
Mud Cleaner: GNZJ703E-D1S8N, 1 set
Mud Cleaner Feeding Pump: GNSB6*5A-37KW, 2 sets, used respectively for desander cones and desilter cones
Mixing Hopper: GNSLS35A, 1 set
Mixing Pump: GNSB6*5A-37KW, 1 set, same specification as mud cleaner feeding pump.
Mud Agitator: GNJBQ 075D, single layer impeller with 7.5KW motor, 1 set
Mud Gun: GNNJQ50A, 2 inch mud gun, 1 set

Besides this standard configuration of mud recycling system, GN also has GNMS-500GL mud recycling system, the main equipment for treating are exactly same, but the storage capacity of GNMS-500GL is larger.
And for HDD mud recycling systems, GN has other treating capacity solutions for option, like 200GPM and 1000 GPM.
In case of piling or so called TBM projects, there are simpler solutions for option. Because for piling projects, the drilling media is mostly water, there is no need to add more chemicals into it, and the treating result is not so strict.

GNLW553C-VFD decanter centrifuge is a big bowl big treating capacity decanter centrifuge which is designed and produced by GN solids control. It has been applied for various industries, for example drilling waste management system, dredging slurry separation system, dewatering unit for TBM waste water treatment, industry waste water treatment, mining tails treatment, oil sludge waste treatment, even solids control system. It is the biggest model we have right now, drived by VFD control panel, the bowl size is 22inch bowl diameter by 71 inch bowl length.

GNLW453C-VFD decanter centrifuge is also big bowl centrifuge with 18inch bowl diameter and 60 inch bowl length.

2015.11.05 2Big Bowl Big Volume decanter centrifuge shipping to Australia

GNLW553C-VFD decanter centrifuge for dredging slurry separation:

With dewatering unit, GNLW553C-VFD decanter centrifuge can be used to separate the dredging slurry and get relatively clear water, which could be drain off to the river/lake. Firstly we use mechanical way to separate big solids, big cuttings, solid trash, and have the clean fluids storage into the mud tank. After treatment by 4 inch desilter cone, over 80% of the particles bigger than 25 microns has been separated out. The discharge solids/trash will be shipped out by truck. The clean fluids will be added polymer and separated by decanter centrifuge, then you will get relatively dry solids with water content 50% and clear water will be storage by another tank and drain off to the river.

One of the disadvantaged by this design is the treating capacity of the dewatering unit with centrifuge is not big enough, so you need to stop the first mechanical separation part( shale shaker, desander, desilter) for a while to let the centrifuge treat the remained water sufficiently. Then start the shale shaker again. But compared with the traditional belt press, the treating capacity is much bigger, and it is with less power consumption.

To know more case study of our decanter centrifuge used for these industries, pls contact GN solids America sales.

The cyclone is widely used in the drilling fluids recycling system for solids and liquid separation. Different brand supplier of solids control equipment may provide the cyclone unit with different size. The most provided size of the cyclone includes 2”, 4”, 6”, 10” and 12”. GN now always provides 2 size of cyclone of 4 inch and 10 inch which are separately used for de-silter and de-sander unit.

By assembling with manifold, the cyclone unit could be used to separate the solids in the drilling mud. GN’s cyclone unit has 2 types, one is without under shale shaker, the other is composited with a under shaker as a mud cleaner unit.

Desander Plant

GN’s 4 inch de-silter cyclone with separation point of 15-20 microns, which means under the feeding pressure at 0.25-0.4 MPa, this type cyclone could remove out the solids at this size from the drilling fluids.

GN’s 4 inch cyclone parts are consisting with shell, cone tube, drop in apex and orifice nut. Always the drilling fluid was transferred into the cyclone through a centrifugal pump under a proper pressure. The drilling fluids get into the cyclone alone a tangent line and make a vortex inside the cyclone body. Then the liquid goes up, and the solid goes down alone the inner wall of the cone under the centrifugal force. As the vortex makes the vacuum inside the cone, the air gets into the cone from the bottom opening on the orifice nut, which leads the liquid overflow and the solids discharged out from the nut as an umbrella shape. The correct angle of the ‘umbrella’ is 20 to 30 degree, over larger or smaller indicates that an improper diameter of the drop in apex, the operator need adjust the orifice nut to ensure the discharged slurry has a proper liquid and solid content percentage.

GN’s 4 inch cyclone is interchangeable with the original Derrick parts. However, the complete unit including the elbow is not available for Derrick mud cleaner manifold. Thus GN Solids Control always only proposes cone body parts. GN could provide the apex with different diameters according customer’s requirements. For more information, please feel free to contact with GN Solids Control.

Because of the special characters of HDD drilling projects, many end users, the HDD drilling operators prefer a portable mud recycling system to be movable from one jobsite to another easily. In order to better serve the need of clients, GN Solids Control has designed and put into practice some solutions per different jobsites condition.

What mud units does GN Solids Control have available?

GN standard designs of mud system could be divided into 2 catalogues:

  1. premium configuration of mud systems, which is suitable for applications including trenchless HDD drillings, CBM drilling or geothermal well drilling, TBM drilling and Bored piling and also water well drilling works. In the higher configuration systems, there are normally 3 steps for separation, including the shale shaker, desander of 10 inch hydrocyclones, and desilter of 4 inch hydrocyclones and a mud mixing system for adding new material into the drilling mud. Because of the function and efficiency of such mud systems, these systems are also called self contained mud recycling system.
  2. economic configuration systems for mud recycling are always used for bored pile drilling, micron TBM, some HDD drilling or small capacity or lower standard, water well drilling and some mining drillings. These mud recycling systems are also called desander plant, because they have 2 steps of separations, the shale shaker and desander cones. In GN’s design, they always us a double deck shaker, the lower deck shaker plays as shale shaker, the upper deck shaker is the drying shaker of desander cones.

1500 GPM Drilling Mud Recycling System

We can see clearly, the two kinds of mud systems serve similar applications, in fact, in practices, the end users are different when choosing their solutions. Some systems are more likely somehow customized. For both configurations of mud recycling units, GN has 200 GPM, 350 GPM, 500 GPM and 1000GPM available.

In order to serve the portable requests of end users, GN also designed for hydraulic hoisting systems used for Australia market, the containerized corner of mud recycling systems used in Singapore, and trailer mounted systems used for middle east and Africa.

GN HDD Mud Recycling System Working Process
GN Solids Control Co. has been working in the mud recycling system for many years. The chief engineer in GN has nearly 30 years working experience in solids control area. GN also has some experienced designers and engineers who keep providing better and better mud recycling systems to worldwide clients.
As more and more companies pay attention to the mud control in no-dig area, such as HDD, Trenching, Boring, Tunneling etc. Today we would like to give you an introduction on GN Economy Mud Recycling System.
Let’s take GNMS-500D as an example, it consists of one mud cleaner with one 10 inch cyclones and one centrifugal pump as well as the mud tank, stand, light.
The working process of GNMS-500D mud recycling system is as follows:
1. The mud is sucked by one pump from the mud pit, it will be sent into the bottom shaker screen for the primary separation. Most of the solids with larger size will be separated out.
2. The fluids that fell into the tank will be sucked by one centrifugal pump to the 10 inch cyclones. GN cyclones are made of PU which is anti-abrasive and can be used for a long time. Finer solids and fluids will come out from the top end of the cyclones, and part the large solids will fall into the upper shaker screen.
3. Then the solids can be further separated by the upper screen. GN mud recycling system is using a compact shaker with double layer which is quite cost-effective with less room and less expensive. The topper shaker screen separate the solids in advance, for the solids that pass through the bottom shaker screen will fall into the bottom tank.
4. The separation process keeps going, and we will get clean fluids at last.

There’s also one fluids height detect switch, it will control the fluids level in the bottom tank with a reasonable amount. For any further questions, welcome to contact us via thomas@gnsolidcontrol.com

500GPM Mud SystemTechnically, 500 GPM mud cleaning system is sufficient for CBM drilling system., the solids control equipment will handle with sands and silts in drilling mud, which are bigger than 20 microns.

 500GPM capacity Solids Control Unit for CBM Drilling Working Flow:

 The mud will firstly goes through GN GNZS703E shale shaker, with shale shaker screens to remove particles larger than 230 Microns. And a centrifugal pump suck the fluids from tank first compartment to feed the 4 inch de silters to remove solids larger than 20 microns.And solids discharge from the desilter Apex will drop down the shaker deck for drying before discharge. If the drillers still want to reduce the density of the drilling mud, GNLW 223 decanter centrifuge can be turned on to remove solids bigger than 5 microns. The jet mud mixing is available for preparing and mixing chemicals in the drilling mud.

About CBM Drilling
CBM is an unconventional source of natural gas produced from gas residing in coal seams. CBM wells are typically shallow (less than 1000 meters total depth) and have a single string of surface casing cemented in place. So the 500 GPM mud solids control unit is very popular for the CBM Drilling.

 GN specialize in the CBM drilling project for many years and provide the reliable and professional solids control unit
