mud recycling system | GN Decanter Centrifuge

Big Bowl Decanter Centrifuge Used for HDD Mud Recycling System

In a common and normal and most cases’ HDD mud recycling unit or systems, there
are separation equipment like shale shaker and desander cones, and a jet mud
mixer for mixing new material into it. But seldom centrifuges used for an HDD
mud system.

In a recent order of GN, China CPP ordered 8 sets of highest
standard 500GPM mud recycling system combined by 2 tanks. One tank is for shale shaker and desanders, the other is
for 2 sets of centrifuges. But the centrifuge tank and the application of the 2
centrifuges are for option, not only mean that this design is for option, but
also that on jobsite work, the operators could choose to use the centrifuges or
not, in order to get different standard fine mud.

These centrifuges are big bowl centrifuges of 18 inch
diameter bowl, which was economic configuration model in GN’s centrifuge family and was designed at a
middle speed of 1800RPM and used mostly in solids control systems for oil
and gas drilling for barite recovery. In this design of the HDD system, it
is used for separate out the particles larger than 2 microns and was customized
to have a VFD control panel to enable the speed to be in range of 0 to 1800
RPM.

In the standard high configuration designs of GNMS-200G,
GNMS500G and GNMS-1000G systems, there are separation equipments like shale
shaker, desander, desilter and mixing devices like jet mud mixer. But if you
think the centrifuge is necessary per your jobsite, we could recommend the most
suitable centrifuge for you. We have 9 inch, 14 inch, 18 inch and 22 inch bowl
diameter centrifuge for option. And for the most popular model GNLW363 14 inch
bowl decanter centrifuge, GN has both fixed speed and VFD control panels
available. For other size decanter centrifuges, some are designed for fixed
speed while some are VFD controlled, but they all have another optional choice.

Mud Recycling System for HDD Machines and Boring Equipments

GN solids control,
with sales
office and warehouse GN Solids America in Houston, is a China based
manufacturer for mud
recycling system/ mud cleaning system/ desander unit/
solids removal unit/ dewatering unit for HDD Machines and Boring Equipments. We
provide not only standard design mud recycling system, also customized design
of mud cleaning and mixing
system.

For the standard
design of HDD & boring mud recycling system, we provide economic solution
and premier solution for your different budget.

GN mud recycling
system applications:

(1) Bored piles machine

(2) Tunnel boring machine

(3) HDD machine

(4) Diamond core drilling,
water welling drilling

(5) Coalbed methane
drilling

(6) Geothermal Drilling

(7) Slurry separation

We have 3 standard
models of economic mud recycling system for option, GNMS-200D( 200gpm treating
capacity),, GNMS-500D( 500gpm treating capacity),, GNMS-1000D( 1000gpm treating
capacity),, this is a compact design which is utilized in the projects which
has limit place to install the HDD machine and mud system, also it is a good
choice if you have limit budget for the project.

The applications of
premier mud recycling system is same. It is a self-container mud recycling
system with recycling, mixing, storage function together. We have 6 standard
models for your option: GNMS-200G( 200gpm treating capacity), GNMS-500B,
GNMS-500G( 500gpm treating capacity), GNMS-500GL, GNMS-1000G( 1000gpm treating
capacity), GNMS-1000GL.

GN self-container mud
recycling system is an economic solution in the long run, because it can be
applied for many different projects, if there is no space limit, it could be
your best option. We do not mean that the premier mud recycling system must be
expensive, compared with the technical specifications, it is reasonable. We use
3 phase cleaning( shaker, desander,
desilter) rather than the traditional 2-phase cleaning(
shaker with desilter cone), it can separate most of the coarse solids from the
drilling mud so you can re-use the water.

High Configuration 500GPM Mud Systems for HDD Rigs

Among all the fields that GN Solids Control
is professional in, HDD Rig’s mud recycling systems or
units are one of the most important and specialist one. Since its establishment
years ago, GN has been providing large HDD contractors in and out of China.
Now, like the largest HDD project contractor in China, CPP, is a long-term
client of GN Solids Control, at beginning of this year, CPP signed order to GN
Solids Control, with 8 sets of 500 GPM mud recycling system, with the highest
configuration.

Each year, GN will produce tens of such
systems, mostly for clients from market abroad, like Australia, Thailand,
Singapore, India, Kuwait, and some countries in Africa. GN has a series of
mature products of mud recycling systems for HDD, with most popular treating
capacity as 200 GPM, 350 GPM and 500 GPM. Of those, 500 GPM systems are most
frequently used in China.

For the same capacity systems, 500 GPM, GN
has different configurations for option, both economic configuration and
premium configuration available.

The most difference between the economic
configuration and premium configuration is the treating equipments. This time,
for the order of CPP, it is the premium configuration, with shale shaker, desander cones with under shaker, desilter cones with under
shaker and 2 sets of decanter centrifuges. For a normally economic
configuration, there is some times a mud cleaner which is combined by a mud shale shaker, a desander and a
desilter, and in most cases there is no centrifuge. And when more treating
equipments are used, there will be larger surface for them, accordingly, the
storage capacity is enlarged.

In case of Piling work or TBM projects, the
mud system, or so called slurry plant is simpler. Normally the slurry for such
projects is not requested to be treated so fine, so there is no need for
desilter cones, only to choose enough desander cones according to the desired
treating capacity. And for Piling mud systems, there is no mixing facilities.

Geothermal energy is thermal energy generated and stored in the Earth

Geothermal energy is thermal energy generated and stored in the Earth, means” earth’s heat”. GN solids controldesigned and manufactured mud recycling/ cleaning system can be used not only for oil & gas drilling, horizontal directional drilling, water welling drilling, diamond core drilling, rotery drilling, coal bed methane drilling , workover rig, but can be also used for geothermal well drilling.

They donot have much difference in drilling technology between geothermal well drilling and other energy drilling like oil & gas drilling, the important one is that the high temperature drilling fluids will damage the equipments, so you need a mud cooler to cool the drilling fluids. A mud cooler or a mud cooling system is an effective device to used for cooling the drilling mud in geothermal drilling or hot oil & gas drilling both in onshore and offshore.

GN mud recycling/ cleaning system for geothermal including the equipments below:

1 shale shaker: We adopt stainless steel shaker deck bottom which is Corrosion resistance, and the sealing rubbers on the shaker deck and under the shaker screens are also Corrosion resistance material.

2 hydrocyclones, we have 10inch hydrocyclones for desander and 4 inch hydrocyclones for desilter, the mud should go through mud cooler before feeding to the mud recycling system to avoid to shorter the service life of hydrocyclones and centrifugal pumps.

3 decanter centrifuge: GN solids control brand decanter centrifuge bowl assy is made of duplex stainless steel, and the other fluids touch parts are made of stainless steel 316L, which is Corrosion resistance and better strength.

GN solids control can design customized mud recycling system for geothermal project, with different treating capacity, wire height, mud tank size, qty and volume, what equipments to be used, etc.
