desilter

500GPM is the most popular capacity mud system for HDD, CBM and other trenchless activities. GN Solids Control dispatched a 500GPM mud system to clients.
Firstly, remove the shaker box locking device of shale shaker GNZS703E-HB and mud cleaner GNZJ703E-D8N (Please refer shaker user manual and mud cleaner user manual for detailed operation). Then have a trial operation to shale shaker and mud cleaner.
All valves for pipelines are on off state after dispatch from the manufacturer’s factory. Before start up the system, operator should open values first and ensure all of them unblocked.

Then, start up shale shaker GNZS703E-HB and mud cleaner GNZJ703E-D8N. After the shaker and mud cleaner is running stably, start up submersible slurry pump to feed for the shale shaker. It is the first stage separation. When the mud reaches to three quarters of the 1# compartment underneath shale shaker (about 1 minute), start up the desilter feeding pump (1# sand pump GNSB6x5A-12J). Mud will be transferred to the mud cleaner 4’’ desilter cyclone from the 1﹟compartment, at a pressure of 0.25~0.40MPa. It is the
second stage separation. The clean mud from 4’’ desilter cone flow to the #2 compartment. When the mud height reaches to the overflow pipeline, it will overflow to #3 compartment. The user-owned mud pump is connected to the suction line of the 500GPM mud system tank and transfer qualified mud to wellhead. The clean mud can also directly flow to outside storage tank through the desilter output pipe.
When needed, users can start up the mixing pump (2# sand pump GNSB6x5A-12J) and feed to the mixing hopper GNSLS35A. The weighted mud from mixing hopper flows to 3# compartment. The suction port and discharge port of mixing pump are equipped with T-pipe, it can also mixing/discharge mud from/to outside tanks.  
Pay attention to the performance of the desilter cyclone. Ensure it works properly. If not, adjust the cyclone adjustment cap for a better performance. Pay attention to the figures on the pressure gauge of desilter cyclone, ensure it is under the scope of the working pressure. The working pressure of 4’’ desilter cyclone is 0.25~0.40MPa.

Shale shaker, mud cleaner and desander, desilter are the most common solids control equipment for different drilling rigs, like oil and gas drilling, Horizontal directional drilling, coal bed methane (CBM drilling), water well drilling, piling, micro tunneling, and other trenchless and underground activities.
GN Solids Control as one of China leading manufacturing for solids control mud recycling system and equipment, they exported some shale shaker and mud cleaner for Hong Kong China for a trenchless project.

GN offers steel frame screen and composite material screens for GNZS594E 4-panel shaker.
2) Fixed speed decanter centrifuges for solids control and barite recovery. Centrifuge model: GNLW363CG. It is the most popular side decanter centrifuge for drilling rigs.
GN and LW means the brand and centrifuge type. 36 is the centrifuge bowl diameter: 36cm. 3 is the bowl length and diameter ratio. 3 is the most popular ratio for drilling rig decanter centrifuges.
3) Some mud agitators and centrifugal pumps.
Even for the accessory small equipment, GN all made per international high standard, with all materials chose from internal and international famous brand.
For mud agitator, GN chose SOG oil seal and FAG genius bearings.
GN centrifugal pump is equipped with mechanical seal. The material for mechanical seal is tungsten carbon for long time. Bearings are from worldwide famous brand FAG.    
Other solids control equipments can be offered by GN Solids Control:
1) Desander, desilter or mud cleaner with under flow shale shaker. GN do offer 2-panel, 2-panel, and 4-panel under flow shale shaker.
2) Poor boy degasser, it is also name mud gas separator. It is used before shale shaker but after BOP to kill the gas in the mud.
3) Vacuum degasser. It is used after shale shaker but before hydrocyclone separator to kill the very small size gas to protect the cones.
4) Jet mud mixer for barite and polymer mixture.

GN Solids America, it is the branch company of GN Solids Control Company Limited. It is located in Houston Texas. With its own office building and warehouse.

GN Solids Control and GN Solids America took part in 2015 OTC oil show with great success. The head company GN Solids Control takes its latest design drilling waste management equipment (high speed decanter centrifuge, vertical cuttings dryer) for the show. And GN Solids America show the mud cleaner separator machine for the OTC oil show. Mud cleaner is a 3-in-1 machine, with the function of desander, desilter, and a under flow shale shaker.

GN solids control mud cleaner for oil and gas drilling showing on OTC
1) Mud cleaner model: GNZJ594E-2S12N
It is the combination of under flow shale shaker GNZS594E, a 2-cone desander, and 12-cone desilter.
2) Capacity of the mud cleaner: 240m3/h (max.)
The capacity of mud cleaner depends on the desander cone and desilter cone capacity. The smaller one is the treating capacity of the whole treating capacity.
Desander cone and desilter cone is on D100 separation machine. There will be some amount of useful mud discharged together with dirty mud. So the function of underflow shale shaker is to further treat and recovery mud and dry the solids discharge.
Some jobsite may use desander or desilter with not under flow shale shaker to save cost. But the performance is surely not as good as the combined one.
3) Feeding pipe size of the mud cleaner is 6’’ and the output size if 8’’. GNSB8*6 centrifugal pump is mostly used to feeding for the desander and desilter.
4) Shaker screen of the GNZJ594E-2S12N mud cleaner: the under flow shale shaker is a 4-panel shaker with long shaker deck. It can make the solids more dryer. The shaker screen is pretention type, and mounted with wedge for fast screen changing.
5) GN patent design for Synchronous adjusting of the deck angle. When the operator adjust shaker angle at any side, both sides will be up or down with exactly the same angle. It saves time of jobsite people and easy for operation.
