Liquid mud plant:

GN solids control already made several complete LMP for our clients, like COSL(China Oilfield Services Limited) for both water based drilling fluids and oil based drilling fluids. That liquid mud plant including 17 sets of standard 40ft container mud tanks(450bbl each mud tank) with necessary mud agitators with JIE Brand gearbox, mud guns with 6.4Mpa high pressure, mud tank accessories and decanter centrifuge with feeding pumps. For more info about this complete liquid mud plant, pls check our website: http://www.gnsolidscontrol.com/drilling-fluids/liquid-mud-plant-lmp-china-oilfield-services-limited-cosl

We ever made a 6 mud tanks liquid mud plant for CNPC division company, with decanter centrifuge GNLW452 with screw pump, mixing hopper, mixing pump, mud agitators,mud gun and charging pump, etc. 

How to design a customized liquid mud plants?

Firstly we need to know the total volume of the LMP, so we can design the mud tank size and we can know the layout of each mud tank, how much bbl each mud tank, and how to fix them in the liquid mud plant.

Secondly we need to know what equipments will be used in LMP, including the mud recycling system, barite recovery centrifuge, high speed decanter centrifuge, pumps, pipelines, mixers, etc.

The mud recycling system including shale shaker, desander, desilter cone, decanter centrifuge, mud tanks, mud agitator, mud gun, mixing hopper, shear pump or mixing pump, etc.

GN solids control designed barite recovery centrifuge system is welcomed to be checked in our Houston warehouse at 6710 Windfern road, Houston, TX 77040.

The configuration of this barite recovery system is as below:

1 GN Hi-G dryer shaker GNZS594E-HB, we have 10 units of such shakers in stock there, it is a 4-panel pre-tentioned screens shakers with total screens area 2.73 square meters. The function of the shaker is to separate the big solids and less the solids content before feeding to the decanter centrifuge.

2 GN variable frequency drive decanter centrifuge for barite recovery

Both of GNLW452 and GNLW453VFD centrifuge can be used for barite recovery, the most common model and effective way is GNLW452 centrifuge, if you want to change the speed based on the mud weight, you can change the pulley and belt, but it is inconvenient to change the pulley, you have to stop the centrifuge, anyway, it is the most economic way.

GNLW453VFD centrifuge is variable frequency drive centrifuge with high volume and high speed, you can change the speed by the PLC controlled VFD control panel if different mud weight.

The other option is to buy 2 units centrifuge, GNLW452 for high gravity centrifuge, GNLW363VFD or GNLW453VFD centrifuge for low gravity centrifuge.

Also with the Nemo brand feeding pump for the centrifuges.

3 jet hopper system

4 catch tank

5 Necessary spare parts, like shaker screens

Also we provide the options to put the shale shaker, 2 decanter centrifuges on one mud tank slid, with 2 VFD control panel and jet mud mixer system.

Except for barite recovery system, we also design the complete system for dewatering centrifuge together with solids removal equipments. For more info about this project, pls contact GN Solids America. Right now we have hi-G dryer shaker and VFD decanter centrifuge for test.

Decanter centrifuge can be used for various industries including food, chemical, paper, waste management, mining, oil recovery, oil & gas drilling, GN solids control brand decanter centrifuge is mainly used for drilling fluids industry, including solids control and drill cuttings waste management.

GN produced drilling fluids decanter centrifuge including high speed decanter centrifuge, low speed decanter centrifuge, middle speed decanter centrifuge and variable speed decanter centrifuge. For high gravity drilling mud, we recommend middle speed centrifuge. For low gravity drilling mud, we recommend high speed decanter centrifuge GNLW363G with 3200rpm rotary speed. If you bought our variable speed decanter centrifuge GNLW363VFD, you can adjust the speed by the PLC control panel. If you bought our rated speed decanter centrifuge, we can provide 3 sets of extra pulleys to change the high speed to middle speed or low speed decanter centrifuge.

For better performance of GN decanter centrifuge, you should pay attention to the following points:

1 Lubrication according to the lubrication chart we recommend, especially for the 2 bearing blocks, gear box, hydro-coupling.

2 Cleaning and flushing: the centrifuge bowl inside and outside should be flushing after every time start, to avoid the solids accumulated around the solids discharge port.

3 Proper feeding capacity to ensure there will not be too much solids accumulation.

4 Use proper speed for different drilling fluids, change the speed by change pulleys or by manually adjustment in the PLC control panel

5 Replace the spare parts in time once any wear parts are damaged

6 separate the big solids by shaker screens or hydrocyclones before feeding them to the decanter centrifuge

7 GN recommend Nemo screw pump as the feeding pump of our decanter centrifuge

8 Proper transportation and storage: During transportation, the safety guard should be tighten; and during operation, it should be released.
