GN Drilling Waste Management Equipemnt for 3 Rigs Roaming Nigeria

Few days before, GN’s
waste management equipment with regard to 3 rigs passed the particular
commissioning and started running inside Nigeria. Total 33 products equipment
were involved such as waste cuttings drying gear, ultra fine solids parting
equipment and transferring products. The pictures was taken through our
commissioning engineer whenever completion of the installation as well as
commissioning.
The client is one of the major drilling contractors in Nigeria, this is already
the 3rd purchase from this clients. Before this particular project, the client
order ten units waste decanter
centrifuge and 1 complete mud plant system from GN Solids Control.
Below back links to the other 2 projects intended for reference:
1 . Liquid Mud Plant System for Photography equipment Drilling
2 . Ten models GN Decanter Centrifuge regarding Africa Drilling Company
All these 33 units equipment are usually listed as below:
three or more set vertical
cuttings dryer which is main drying devices for waste cuttings, with all
the max. speed up to twelve hundred RPM, the G pressure could be up to 750.

some sets high speed VFD decanter centrifuges would meet the client’s different
requests on surgery speed and waste ailments.
Total 9 unit twist pumps, with 6 of those for feeding the aura discharged out
from the vertical cuttings dryer to decanter centrifuges, while the other 3
model for flushing to clean typically the cuttings dryer.
15 established screw conveyors are located about site accordingly for switching
the drilling waste into the dryer unit and accumulating the solids discharged
in the dryer and centrifuge.
In accordance with the feedback from the client, immediately after several
orders of GN’s equipment, they are very more comfortable with the performance.
This time, they will replaced all the equipment at a USA brand that pricing a
little high by using GN’s equipment with good feedback on both the cost and
performance.

GN nowadays has developed a series of tools especially for drilling waste
management also including the dewatering system and solidification unit. When any
request aroused, simply feel free to contact with us.

Dredging Slurry Separation System

It is very strange that China even
have more strict environmental requirement on the dredging field than all over
the world, on the waste solids disposal and also the fluid dump, no matter
how it have been applied on field, in paper it is really advanced. So
basically when the oil market is down, we get a chance there, some client
in dredging field said. Just like you have done in drilling
waste management field. Also we have realised that not
only china all over the world, people are taking more care on the
environmental protection. For dredging, what we need is: Recycle the cleaner fluids.

Dump and reuse as much as possible on
the solids.

Not like the oil gas drilling, from the
pond, or from the river, from sea, there are sands, rocks, and other
things as you can imagine which have been buried in it. So
the separation seems very different. Except the basic concepts.

Separate the biggest particles and
other stuff other than the sands and silts. There are many ways to do this, one
is dig another pit / pond, with at big screen from where dredging pump
feeds, let the screen separate unreasonable parts to the pond, keep them away
from the progress. Another way is gumbo box, it is quite same as
the mining applications, to separate the biggest rocks from the first
step, then others feeding directly to the shale
shaker.

Then directly, or by another pump from the
pond. The feeding goes to the double deck shaker. In GN Solids Control , it is GNZS706E,
which is good to separate the bigger sands and the most of
the bigger solids. going through two sieves.

Catched by the pump, feeding to the
cyclones, to get the silts separated.

Then in the same way, separated by the
decanter centrifuge.

Sometimes it also need help from chemicals
that why a flocculent unit is there. To concentric the small particles
to be bigger ones, then easier to be separated.

Kindly contact GN for a full solution.

GN Total Solution for drilling waste management

GN Solids Control is the first Tiongkok
drilling waste management gear company who can offer full solution for drilling
waste management Service Company.

Regarding Oil-based mud drilling cuttings, the entire solution of drilling
waste management including below methods:
Step 1: Vertical
cuttings dryer. Use this VG dryer to take care of the drilling cuttings,
get the valuable oil based soil. The OOC after cure can be 3%-5%.
Step 2: Energy Desorption Unit. After VG dryer, the solids can TDU for
nonhazardous ultimate treatment. After TDU, this inflatable water, oil and
solids may be separated in accepted level which comply with most of country’s
government policy on enviromentally friendly protection
Step 3: Decanter
Centrifuge. After VG dryer, typically the liquid part (drilling fluids) can
go to centrifuge to remove often the fine solids and get back to active mud
tank regarding reuse. Some client allow liquid part discharged via VG dryer go
back to lively mud tank
system immediately. This is also OK.

Regarding normal water based mud drilling clippings, the total solution of drilling
waste management including down below steps:
Step 1: High Grams drying shaker ( HG dryer). Use this HG dryer to treat the
drilling waste, recover the valuable drinking water based mud for using again.
The mud on waste after treatment can be all-around 10%.
Step 2: Solidification product. After HG dryer, the actual solids part can be
put straight into solidification unit to blending with cement or chemical
substances to get nonhazardous treatment.
Step: Decanter Centrifuge. After HG dryer, the liquid aspect (drilling fluids)
can go to centrifuge to remove the fine solid waste and go back to active
magnetic tank for reuse. A few client let the liquid portion discharged from HG
dryer go back to active mud container system directly. This is also ALL RIGHT.
GN Solids Control will be the
first solids control devices supplier with China basic & USA base and
Russia base from China. All of our equipment is working in over 70 countries
and areas, increasing good reputation from many purchasers.

Positive pressurized VFD control panel for variable speed decanter centrifuge

As one the lead decanter centrifuge
manufacturers in the world, GN solids
control( with branch office GN solids America in Houston) provide both high
speed decanter centrifuge and variable speed decanter
centrifuge with VFD control panel, VFD decanter centrifuge the most popular
model during our clients from over 60 countries in the world.

We provide 4 types VFD control panel of
decanter centrifuge based on different clients requirements:

1 positive pressurized VFD control panel for
explosion proof Exd II BT4 with PLC control

2 positive pressurized VFD control
panel with IEC certificate with PLC control

3 positive pressurized VFD control panel with
ATEX certificate with PLC control

4 flame proof/ explosion proof control panel

The positive pressurized VFD control panel is
specially designed for the working site with high temperature, moist air, heavy
rain, strong sunshine area with good performance. To ensure the long operation
life, we also suggest to use a sun/rain proof cover on top of the centrifuge
unit, as GN
drilling waste management project in Sichuan, China, Where is a lot of rain
and very moisture air.

With air cooler inside the control cabinet, we
have a temperature sensor installed and setting according the environmental
temperature and client’s requirement, once the inside temperature reached the
setting value, the cooler unit will start to work and feed to the inside
cabinet cold air and let the warm air out, the constantly circulation make the
inside cabinet to remain the respectively cool and will not be too hot during
long term working in the hot weather.

PLC control VFD control panel change the
frequency smartly, the last flame proof/ explosion proof control panel can not
work in hot weather, the electric components will be too hot to stop working or
be burned when it becomes hot. And the frequency inverter is working through
very traditional way. Such products are only supplied to the cold area or when
cheapest price is required by the client.
