GN Solids Control as the leading manufacturing company for the solid control equipment and mud recycling system will attend the show this year and will present its latest mud recycling system. The booth number is E3. 675, welcome all the friends from domestic China or overseas to visit GN.
GN’s mud recycling system could be used in many areas, such as the TBM, HDD, piling, boring, oil and gas drilling, civil construction, dredging, etc. According to different customer’s requirement and the different situation for each project, the mud recycling could have different configurations and different equipment in it. Usually the mud recycling system will consists of shale shakers, mud cleaners, desanders, desilters, decanter centrifuge, centrifugal pump, different tanks, mixing hoppers, submersible pump, screw pump, etc. According to customer’s different separation requirement, the mud system will include different equipment. The hydrocyclones could separate the solid size from 20-40 microns. The shale shaker will be used as the scalping purpose to separate some big solids. The decanter centrifuge could be used for even finer separation for the solid size of 2-5 microns. After the solids to be removed and the mud could be reused in the mud system again for drilling.
Welcome again to GN’s booth in Bauma China 2016. We believe you have got a different feeling for the mud recycling system used in the civil construction. If you have some further interest, welcome to visit www.gnsolidsamerica.com and please send your inquiries to USA@gnsolidscontrol.com .

Mud cleaning system is critical in the drilling process as they protect the system components by lowering solid/sand content in the drilling fluid. Cleaner fluids means much longer and expandable life in the entire mud cleaning and pumping system. Lowering solid content also allows drilling fluid to carry the sand from the bore more efficiently, making for a better bore hold and improving the rate of penetration dramatically. And it can also solve the environmental and disposal issues and save a lot of cost.

GN Shale America
GN’s mud cleaning system are made on skid, like modular, which makes it very easy for transportation. The mud system mainly includes five components: shale shaker, shaker screens, hydrocyclones( desander, desilters), mud tanks, and electrical motor and centrifugal pump. GN’s shale shaker is mostly in linear motion and is used for the coarse separation. It mainly separate the solids by its size by the screen. For the screens, GN now can manufacture its OEM screen with GN brand, also it can manufacture some famous replacement screens, such as DERRICK, MI-SWACO and BRANDT. After the shale shaker, the mud will be pumped by the centrifugal pump into the hydrocyclone which uses centrifugal force to separate the solid from liquid. It can separate the solid size up to 20 microns. The mud tanks usually have 3 compartments, which will hold the mud coming from different separation stage. The size and capacity will depend on the drilling rig size and fluid flow rate. Now GN can manufacture and supply all the components with high quality and low cost.

Containerized Dewatering Unit

The coagulation and flocculation unit
(hereinafter referred to as the CFU) is intended to serve as the mobile
unit for centrifuges chemical improvement while the drilling mud cleaning
(extraction of “process water” non-combined solvent and removal of the “drilled
solids, solid and dissolved chemical reagent” solids from the mud by
preliminary chemical treatment of the mud and subsequent phase separation in
the centrifuge).

The GNDU2000 Series 20FT Dewatering Unit
provides a process of chemically enhanced configuration to remove the fine
solids less than 5 microns from the water based drilling fluids. As it known
that traditional solids control equipments like shale
shaker
, desander,desilter,
and decanter
centrifuge
will removes solids upper than 5 microns, for colloidal-size
particles which is less than 5 microns will build up in the drilling mud
system. To maintain the drilling mud properties, the operators have to dilute
the drilling fluids with water, this consumes more water and create more
drilling waste.

The mud to be cleaned is supplied from mud tanks to the
station by the centrifuge feeding pumps. The mixing device (mixer) is installed
inside the CFU. The CFU process equipment perform the mud mixing (dosing) with
chemical reagents in the mixer, then the mud is fed from the CFU to the
centrifuges. Centrate (process water) obtained in the centrifuges returns to
the CFU, and solids contained in the mud are removed by the centrifuge and
transferred into the sludge transporter. Centrate (water) is measured in the
CFU and if its parameters are satisfactory, the station pumps transfer it into
the tank (receiving tank) for the new mud mixing. If results are not
satisfactory, the centrate is pumped into the sludge transporter.

Mud and water are delivered and discharged
from the CFU by flexible hoses. The water supply system shall provide water
flow rate of approximately 3 m3/h for mixing in tanks. Centrate overflow,
centrate output to the storage vessels, centrate output to the control vessel,
water input/output, mud input to cleaning shall be designed with quick-release
couplings DN50 and shall be located in the same port on the CFU outer wall. The
port is covered by cover with padlock. 50 meters of flexible hoses are included
into the scope of delivery. Centrate is fed into the centrifuged water tank by
DN150 pipeline. Pipeline inside the CFU is made of constructional carbon steel.
Flange and gooseneck outside the CFU is made of constructional steel and
intended for centrate feeding from two centrifuges. The flexible hose DN150
delivers centrate. 10 meters of flexible hoses are included into the scope of
delivery. All quick-release couplings, flanges, bolts, goosenecks shall be
included into the scope of delivery also.
