GN Nodig Mud Recycling System

Decanter Centrifuge is among the most
typical and well-known equipment in drilling mud solids control project. It’s frequently utilized
as the 4th stage solids control equipment to get rid of the best fine solids.
To some degree, the performance from the centrifuge determines the prosperity
of the work.

How you can define the capability from the
horizontal sedimentation decanter centrifuge

The majority of the oilfield application
decanter centrifuge producers worldwide claim the capability that is examined
using the water. Go ahead and take GNLW363BG normal size bowl centrifuge
for instance, the nominal capacity is 132GPM, this capacity is perfect for
water and also the actual dealing with capacity could be various based on the
drilling mud condition or any other factors. That’s why when customer asks how
is the capability from the centrifuge, GN always asks the consumer to supply
just as much information from the drilling mud as you possibly can. Normally,
the solid content percentage and distribution, the mud density and viscosity are
essential needed.

How you can choose the appropriate decanter
centrifuge according the reason

The decanter centrifuge is classed as
middle speed and high speed; GN team suggested choosing the decanter centrifuge
rotation speed according the work purpose.

a. For barite recycling, the G force
700-1000, RPM around 2000

b. For low gravity solids separation, the G
force 1800-2300, RPM 3200

C. For High gravity solid separation, the G
force 1000-2000, RPM 2500

How you can adjust the centrifuge technical
parameters for correct operation

You will find some parameters from the
centrifuge throughout operation have to be given more attention for easily
working and specified performance result. The parameters here involved will be
the bowl speed, the differential speed, the feeding flow rate and liquid
discharge port plate adjustment.

If you prefer a large treating capacity,
you will want enhance the differential speed by raising the bowl speed.

If you would like the liquid as clean as
enough, you’ll need enhance the bowl speed, lessen the differential speed, and
lift the liquid discharge plate to some high position, thus the mud would
remain in the bowl for extended time, and also the liquid pool could be deep.
More solids could be sediment for the bowl wall. Then liquid released out might
have less solid particle.

If you wish to the released solid material
much dryer, you are able to enhance the bowl speed, lessen the differential
speed, minimizing the liquid discharge part plate position. Then your liquid
could be released rapidly, and also the solid could have a lengthy distance for
dewatering when discharging from the cone slope in the small finish from the bowl.

An effective feeding flow rates are
important too for well performance from the centrifuge. Usually, the operator
would try several occasions with various flow rates to select a finest one.
This is often implemented only through the variable speed control pump.

GN Solids Control can provide decanter
centrifuge for fixed speed and Variable speed. To learn more, don’t hesitate to

As an expert of solids control system for oil and gas drilling and drilling waste management system, GN solids control designed a new system with dewatering unit for a Singapore client. Recently, GN engineer just came back with the working video of this dewatering and drilling waste management system from Singapore. 

 

Firstly, the water slurry in TBM will be treated by a double deck shale shaker: the upper shaker deck mounted with 2mm opening screen is to separate coarse solids; the bottom shaker deck with API 20 screens. After processed by the shale shaker, the slurry will be pumped into the desander, particles over 45 microns be separated out, meanwhile there will be an underflow shaker to dry the down flow stream with screen of API 200. Before slurry being delivered to the decanter centrifuge there will be a stream of flocculant prepared by the dosing system combining with the slurry, and then the mixed slurry will be delivered to the big bowl decanter centrifuge for dewatering process. The fine solids will be separated, leading to clean water and dry solids. Working video is available in the below link: http://gnsolidscontrol.com/video/gn-solids-control-drilling-mud-dewatering-system-working-video

GN solids control is qualified to provide all solids separation equipment and system, normally including the below steps:

Step 1: over 100 microns particle be separated by shale shaker;

Step 2: 50-100 microns be separated by desander;

Step 3: 20-50 microns be separated by desilter;

Step 4: 2to10 microns be separated by medium and high speed decanter centrifuge;

While, if for ultra-fine solids between 0-2 microns, chemically enhanced centrifuge needed.

GN solids control always tries its best to find solutions for its client according to there requirements and problems, that why GN solids control system is well accepted by its customers.

GN Solids America is set up in Houston Texas that is warehouse and purchase office. We’re investing to supply a full-range of solids control models and corresponding spares. Allow me to introduce what you can find from your warehouse
