mud solids control

GN Solids Control and GN Solids America will come and attend 2015 OTC in Houston. OTC, full name is Offshore Technology Conference, is said to be the largest Exhibition in petroleum field in the world. The second one is CIPPE in Beijing. Every year, there will be around 3000 companies from 40 countries attending the show.

In 2015 OTC, GN will take its latest design drilling waste management equipment. And drilling waste management is the main and most advantaged products of GN Solids Control (China) and GN Solids America (U.S.A).

GN 2015 OTC exhibition information

OTC location: Reliant Park Houston, TX, USA

Exhibition time: May 04-07, 2015

GN Solids Control (China): Reliant Arena, 290 SF, booth No.: Pending

GN Solids America (USA): Reliant Arena, 200 SF, booth No.: 6137

GN will show complete line drilling waste management equipment for the show. It includes but not limited to below list:

1) 14 inch high speed decanter centrifuge GNLW363C-VFD, variable speed control

It is the most normal size decanter centrifuge used for both solids control system and drilling waste management system with its reliable performance and cost-effective price.

2) Big bowl big capacity decanter centrifuge GNLW553-VFD, variable speed control, 22 inch big bowl size

As more and more customers prefer solids control systems only with shale shaker, it request s high standard of solids control decanter centrifuge. GNLW553-VFD is an ideal model to used together with solids control shale shaker.

Furthermore, GNLW553-VFD big bowl centrifuge is also widely used for drilling waste management system.

3) Drilling waste vertical cuttings dryer   

GN patent design vertical cuttings dryer can be used to treat OBM, SBM as well as WBM. Customer can use the same system to treat most kind of mud.

All above equipment, GN has stock available in Houston, U.S.A. GN Solids America is a separated brand registered in Houston TX in year 2013. It is the first U.S.A based Solids Control manufacturer from China. GN Solids America offers sales service and rental service in America. You can contact GN Solids America for more information.


Per different control system, there are fixed speed decanter centrifuge and variable speed control (VFD) decanter centrifuge.

Features of fixed speed control centrifuge

As the bowl speed and conveyer speed is fixed, cannot be changed, fixed speed control centrifuge is easy for operation and maintenance. And price lower compared with the same model VFD centrifuge.

Feature of variable speed control (VFD) decanter centrifuge

For the same model centrifuge decanter, VFD model cost more than fixed speed. Per International Explosion-proof standard, there should be positive pressured control panel for variable speed control for better cooling. It requests more professional on operators for the VFD decanter centrifuge.

For GN design VFD centrifuge, the bowl speed, conveyer speed and feeding pump flow are all flexible. Customer can change one or all of the 3 parameters to get the best separation performance in different jobsite. An and customer can change centrifuge parameter for getting the max. capacity centrifuge can reach.

Take GNLW363BG-VFD centrifuge for example, below steps show you how to find out the max. capacity of the centrifuge

1) For a bigger capacity, we should reduce the BOWL speed and increase CONVEYOR speed.



Pump running model set as AUTO

Then pump will running to the max. capacity it can reach.

2) Or you can try more settings to compare the capacity, with pump AUTO running:

a. Bowl 1600rpm, Conveyer 34rpm

b. Bowl 1800rpm, Conveyer 38rpm

3) The back drive motor is opposite rotating under low speed and high conveyer. If centrifuge shut down during running , reduce Conveyer speed.

4) For this centrifuge, the max. capacity will be not over 30cbm. As the pump max. capacity is 30cbm.
