Higher Environment Standard for Oil & Gas Waste Management

Although the price for crude oil is dropping form an extremely high place to anunexpected low place, the global demand for the oil never ceases. But as longas the drilling projects are done everywhere in the world, the environment
effects are shown more and more clearly.

Now more and more countries are issuing
laws and regulations for protecting the environment. Before, in some places,
after drilling, the drilling cuttings could be buried in a remote place, but
now, nothing is allowed to be discharged without further treating. In some countries,
any drilling work is allowed without seeing an existing waste management
solution or system.

Depending on different drilling fluids, the
waste management system is a bit different. Normally, there is WBM and OBM.

1.      Complete WBM waste management system.

A complete WBM waste management system is
combined by 2 sections. First section, standard waste management system
includes a drying shaker with a high G force and a high speed decanter
centrifuge.  Second section is further
treatment, a dewatering unit to flocculate the fine particles into larger ones
in order to be treated by a high speed decanter centrifuge, here, the
centrifuge may be same as the former one, but this one is regarded as
dewatering centrifuge. This whole system is called as zero discharge drilling
system.

2.      Waste
management system for OBM

The complete waste management system for
OBM could also be regarded as 2 sections, the standard one and further one. The
standard waste management system for OBM is combined by a vertical cuttings
dryer and a high speed centrifuge.  After first stage, the further stage is to
make the cuttings more compact and into solid before discharge.

GN Solids Control is most famous China
brand for solids control and waste management systems and equipments. They are
producing high speed centrifuges for waste management, and their products are
of high cost-effectiveness. And also, GN Solids Control is first Chinese
company who designed the vertical cuttings dryer years
ago. Now their vertical cuttings dryer reached the 4th generation, which could provide
more applications suitable for not only OBM and SBM, but also WBM.

If you need to know more about GN and GN
products, you are welcome to attend the coming CIPPE in Beijing, Capital of
China.

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.

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.
