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.

Decanter centrifuge noise

Highnoise made from machine now become part of occupation hazard for works who
expose it in extend of time period.  It
how have regulate by government  because
the consideration of the machine design.

Decanter
centrifuge is the machinery with rotating bowl and contain many number source of
noise .  The size of the machine, the
speed of the rotating bowl, which is the main source of noise come from
structure.  Other noise like turbulence
noise and siren noise is also part of noise production from the decanter
centrifuge.  

Structure
noise often produce by all surfaces that directly coupled to the bowl’s
bearing.  The speed of rotation of the
bowl, it create turbulence from the different trailing edges that produce broad
spectrum vortex  noise.  The siren noise is from air flow through the
bowl and it produce great noise especially
at the lower harmonics of the bowl rotate frequency.

There
are ways to decrease noise that produce by decanter centrifuge, some of them are:

·        
Decoupling
the surface of the main bearing of the rotating bowl and will reduce the amount
of noise transmitted from the decanter centrifuge structure

·        
Polish
and smooth the bowl surface will minimize the noise produce from the edge that
vortices that shed and produce vortex, turbulence noise

·        
Siren
noise produce because from the air flow through rotating bowl, which is the
purpose to the function  of the decanter,
the exit opening should be design so the noise is produce within the parts of
spectrum of sound have low noise level

The noise that
produce from machinery is consider health hazard if personal consistently
exposure on noise that is great then 80 to 85 dB over an eight hours per
day.  Excess expose of level of 85 dB
during work life would result 90% of people suffer lost of hearing.  It can also damage the way of speech as
well.  Which now noise regulation is the
must enforce regulation.

The Introduction of Solids Control Models

Performance and excellence of drilling
solids control equipment is paramount to the introduction of solid control. Drilling solids control
system includes drilling fluid recycling tank, drilling fluid purification
equipment and drilling liquids mixing equipment of three parts. Drilling fluid
purification equipment mainly includes shaker, desander, desilter, degasser,
centrifugal machines, centrifugal pump (sand pump), shear pump, mud agitator and hopper etc. Under highly
restriction eco areas, you may also concern the drill cuttings recovery and
waste treatment plant.

 Solid control equipment trends:

 Drilling operator is expecting small
footprint, high quality, lengthy existence of apparatus and integrated high-speed decanter centrifuge, automatic recognition and
performance solid control system.

 Worldwide Solids Control Company:

 The majority of solids control equipment has
been in the United States including BRANDT, SWACO, and DERRICK along with other
companies. Their performance and quality are on top level on the planet.
They’re focusing on optimizing solid control system configuration and
efficiency of solid control system,

 China Solid Control Company:

 Lately, China solids control company has
accomplished a larger degree of development, mainly in the study from the
theory, for example shaker works, cyclone works, happen to be around the
world’s advanced level. The space between Chinese solid control company and US
solids control is lowering. Especially GN Solids Control is among worldwide
level solid control company which released their models to around the globe. GN
not just focuses on the standard solids control models for example shale
shaker, mud cleaner, mud agitator, centrifugal pump and hopper, but
additionally researches around the advanced waste management area including
vertical cutting dry and decanter centrifuge combination. However, GN follows
worldwide strict quality inspections on each and every model to make sure GN
worldwide quality and equipment safe issues.

 GN Solis Control is constantly on the
supply equipment throughout around the globe, North and South US, Australia,
Europe, Africa and Asian. Our worldwide clientele has provided us the chance to
service industries including Environment, Construction, Chemical/Petrochemical,
Pulp and Paper Manufacturing, Mining, Oilfield/Drilling, Dredging, Governmental/Municipal,
and Energy Plants.
