decanter centrifuge

It is always being good to have duplicated orders from
client, this implies a lot. Just as our own regular decisions, if we are not
pleased with some products, we will go for another one. There are too many
alternatives, this is the third drilling
cuttings dryer system
for this identical client. As we know, Russia going
operation normally under cold weather, this need the gear to specially designed
for cold weather.

The Main Equipment for this job include following:
1) 1 Containerized Vertical cuttings Dryer system with winterization
2) 3 Screw Conveyor, a couple of for feeding the cuttings dryer, one for launch
drilling cuttings from the dryer.
3) Two sets decanter
with one VFD and one fixed speed. These two decanter centrifuge
is actually on the solids control tank, but they are for handling thedrilling mud
from solids control tank as well as the drilling body fluids discharged from
the cuttings dryer.
4) 3 screw pumping systems, one for cuttings dryer flushing, the other two with
regard to feeding the centrifuges.
Therefore except lower down the price, this is the way we survive in the
unpleasant time. Can not say we now have how many fans, but GN Solids Control now already have
a lot of buyers support, with their advise, using sticking to GN brand, GN is
getting better and far better now.

solids control system could eliminate the large solid particles within the
drilling mud to reduce the particular solids content so that to guard the
transferring pump which used to transfer the mud back the rig with regard to
reusing. GN just done one set mud solids control system with VFD
decanter centrifuge
for gold mining project in Southeast Okazaki, japan.
This system is a 3 stages separation design model; the equipment configuration
is as beneath:
1 . Shale shaker unit GNZS594E-HB used for coarse strong particle separation.
This shale shaker unit could also be employed as a high G pressure drying
with variable G force up to 7. 4-panel screen makes a bigger area
for drying the actual drilling mud.
2 . VFD design decanter centrifuge device used for fine solids splitting up.
The first one unit centrifuge goes at a middle speed to eliminate most of the
solids to reduce the particular gravity. The following second system VFD
control centrifuge might run at a high speed to get rid of the ultra fine solids
to make the drilling mud

3. Screw pump set up to transfer the mud to the centrifuge. Horizontally put in
at the flank of the tank, it helps to tank leading more space for operation
4. Mud catching tank
used as sand snare and active mud safe-keeping.
This system is to get rid of the solid particles in the going mud to make the
drilling essential fluids reuse. After the solids currently being removed, the
fluids may be pumped back for recycle and the pump would be
additionally protected as there are less solids particles.
Mud solids control system is very common merchandise and solution that GN
provides. For this purpose, GN might provide separation system intended for oil
drilling, no drill down drilling project and some different industrial solid
and chemical phase separation. For more information, delightful send us email
or even call with no hesitate.

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
, desander,desilter,
and decanter
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.

The particular solids control system might
remove the large solid contaminants in the drilling mud to minimize the solids
content to ensure that to protect the transferring send that used to transfer
the particular mud back the machine for reusing. GN just simply finished one
set mud solids control system along with VFD
decanter centrifuge
intended for mining project in Southeast Asia.

This system is a two stages separation design product; the equipment
configuration is as beneath:
1 . Shale
unit GNZS594E-HB used for coarse strong particle separation. This
shale shaker unit could also be utilized as a high G pressure drying shaker
with variable G force up to eight. 4-panel screen makes a more substantial area
for drying often the drilling mud.
2 . VFD design decanter centrifuge system used for fine solids separating. The
first one unit centrifuge operates at a middle speed to eliminate most of the
solids to reduce often the gravity. The following second device VFD control
centrifuge might run at a high speed to get rid of the ultra fine solid waste
to make the drilling mud clean.
3. Screw pump prepared to transfer the dirt to the centrifuge. Horizontally set
up at the flank of the reservoir, it helps to tank leading more space for
operation mobility.
4. Mud cleaner reservoir used as sand pitfall and active mud hard drive.
This system is to remove the sound particles in the drilling soil to make the
drilling fluids using again. After the solids being taken off, the fluids could
be piped back for reuse as well as the pump would be also guarded as there are
less solids dust.
Mud solids control strategy is
very common product and alternative that GN provides. For this reason, GN could
provide parting system used for oil going, no dig drilling task and some other
industrial sturdy and liquid phase separating. For more information, welcome
send you email or call devoid of any hesitate.

As first API certified solids control
manufacturer in China, GN Solids Control has provided to more than 60 countries
and regions with its cost effective products, covering all related main
equipment of solids control and waste
line for oil and gas drilling

The main principle of the
solids control systems
is physical separation, using the physical
characters of different media, the solids control equipment separate as much
solids from the liquid. Right now, in other industries besides the oil and gas
drilling, such functional equipments are also chosen by the end users, to make
their work more efficient and easier

Physical Functions of solids control

Since the most important solids control
equipments are respectively shale
and decanter centrifuge, we talk about only these 2. Now in many oil
and gas drilling jobsite, the end users choose to use more shakers and
centrifuges instead of former hydrocyclones.

1. shale shaker. Shale shaker is the most
efficient equipment in solids control process, because it uses less energy
while separates the most solids out of the liquid by using the different size
of the solids and by means of different size mesh on the shaker and a couple of
vibration motors. The disadvantage is that the shaker could not separate very
fine particles, and its separation work is a bit draft. GN has 3 nos screen
shale shaker and 4 nos screen shale shaker for option with model GNZS703E and

2. decanter
is a high speed rotation machine, mostly horizontal. It has a
high speed rotating bowl and inside bowl there is an impeller. During the
rotating, the centrifugal forces on different material are not same, that
causes the liquid phase continuously flows out of the bowl while the solids
particles are slashed on the bowl inside wall and pushed out of the centrifuge solids
discharge ports. The decanter centrifuge a gentle and precise, more costly than
shale shaker, not only the cost of itself, but also the consumption of electric
power. But it is ideal solution for separating out the fine and extra fine
particles. GN centrifuge family covers all common sizes of decanter centrifuges
from 9 inch bowl diameter to 22 inch bowl diameter, among those centrifuges,
GNLW363 with 14 inch bowl is the most popular model
