desilter | 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.

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.

GN Decanter Centrifuge to Africa Customer

As an expert in solids control equipment andsystem, GN solids control manufactures and exports a complete set of
solids control equipment and system including shale shaker, desander, and
desilter and decanter centrifuge. At the beginning of this year, GN solids
control received a repeated order that a customer with which GN has cooperated
for more than three years, and this customer is satisfied with GN decanter
centrifuge, high quality with competitive price. And this time, GN has
updated its design for more stable and better performance with several update.

The updated decanter centrifuges still has
the below advantages of the last edition.

1. The
cylindrical and conical section of the bowl is made from duplex stainless steel
2205 which is better than stainless steel 316L. Stainless steel 316 is always
adopted by China’s other solids control company; even stainless steel 304 is
adopted.

2. The bowl is manufactured by centrifugal cast which means that the bowl has a
better balance. Only the decanter centrifuges pass the balance test, they can
be delivered.

3. Tungsten
carbide tile is attached on the screws to protect the screw from wear, and when
the tungsten carbide tiles is worn out, it is easy and convenient to replace
with re-doing the balance test.

For the updated decanter centrifuge, there
are more advantages:

1. Solids
discharge cover is added above the solids discharge port to prevent the solids
discharged to the inner cover of bowl.

2. Special
ceramic mud distribution port on the screw will extend the decanter centrifuge’s
service life.

GN solids have made it policy that GN
solids control will keep to update its product for better service and provide
better services. It is a wonderful start in 2015 with the big order from a customer,
the first batch has been delivered, and the second will be delivered soon.

Hydrocyclone Installation

The mud that contain drilling cuttingreach the ground surface, the process of filtering begin start with shale shaker that contain the shale shaker screen indifferent mesh. The whole process also
depends on the ratio of liquid and solids in the mud as well. While treatment through shale shaker screen is necessary, it is
far from enough and that is what hydrocyclone come to use to take the
filtration to next level.

Hydrocyclone filter less aggravate
solids that is size 15-20um, after the shale shaker. It is install convenient to flow bottom and
also convenient for maintenance and monitoring the filtration of the drilling
mud. The large (10 inch) diameter of
hydrocyclone should be install on upstream and the small (4 inch) diameter of
hydrocyclone should be install follow by large ones. The hydrocyclone need to pair with drilling fluid tank and centrifugal pump.

GN Solids
Control’s desander have installation of 10 inch hydrocyclone
which contain between from 1 cone to 3 cones to meet the different filter
need. To take the filtration further, it
pair with shale shaker that is detachable for convenience in change machinery
to meet the project need and maintenance.
The 4 inch hydrocyclone is for GN Solids
Control’s desilter which contain between 8 cones to 16
cones. The structure of the desilter is
same as desander that pair with shale shaker as well. The desander will remove the +40 microns of solids
and desilter will remove +20 microns of solids.
The shale shaker pair with desander and desilter is linear motion with
either 2 Martin or 2 OLI brand motor
which can produce adjustable G force up to 7.5 G of force. The panel of screen
are choice of 2, 3 and 4 depend the need of the drilling
project. All equipments construct in
explosion proof and meeting different region’s explosion proof standard.
