November is one of the best months in Middle East, when the weather is not so hot. It is also the best season for the business and opportunities for oil and gas industry, because one of the biggest oil shows, ADIPEC, will be held in Abu Dhabi, which will attract nearly every big player and important manufacturer of oil and gas industry in the world. –GN Solids Control


GN will attend ADIPEC 2017

As the capital of Middle East’s most open country UAE, Abu Dhabi is not only the political center. Also, Abu Dhabi has more than 95% share of UAE’s crude oil reserve. ADIPEC will not only attract the companies, which are mostly big buyer in the world from Saudi Arabia, Kuwait, Oman, Iran and etc, but also the big oil companies, oil drilling companies and oil service companies from all over the world.
China is a new trend of power during the past decades. Most of equipment including the drilling rigs and solids control systems, and also the raw materials as steel and tubes, nearly everything are made in China. GN Solids Control, as the leading brand in China and one of the most famous brands in the world, are more and more popular.
Unless previous several times when GN attended ADIPEC with new models of GNLW series decanter centrifuges, this time, for ADIPEC, GN will attend with shaker screens. Shaker screen is one of GN’s core products, by upgrading the producing line, GN has developed the high quality composite material frame screens for frame screens. In near future, GN will make PMD screens into composite material frame, which could endure a longer storage time, a better human oriented, and more important, a longer service life. Now, GN is holding a big promotion on composite material frame screens. Welcome to contact GN for more information.

Among all the decanter centrifuges used for solids control and waste management systems for oil and gas drilling, they could be divided into big bowl centrifuges, medium sized decanter centrifuges and baby centrifuges. Per bowl rotating speeds, they could be divided as middle speed decanter centrifuges and high speed decanter centrifuges. Per their electric control system they are fixed speed and variable speed available.

Like GNLW363C series decanter centrifuges, GN has 4 models while 5 options available, they are highest configuration ones, for waste management use mostly, and economic standard ones. And for each configuration, end users could choose fixed speed or VFD control panel. For the economic standard option, GN has positive pressurized VFD control panel with PLC and normal VFD control panel for option.

centrifuge feeding pump

mono pump

What feeding pumps are used respectively or the decanter centrifuges per their control panels’ differences?

  1. For fixed speed control panel decanter centrifuges, you could use both the submersible slurry pump and the screw pump or called mono pump. In case of fixed speed decanter centrifuge, normally no need to change the speed and feeding capacity which is already set with a formula of centrifuge feeding speed and gearbox ratio and motor rotating speed, and etc. In order to change the feeding capacity when using the submersible slurry pump, extra liquid fed to the centrifuge could flow back via the overflow pipeline of the centrifuge. In case of the screw pump, the end user could install a mechanical devise on the screw pump as a manual valve. Such is shaped as a wheel and could be switched left or right in order to get a suitable feeding capacity.
  2. For the VFD controlled decanter centrifuges, the common and practical solution is always the mono pump or screw pump. The screw pump’s motor is connected with the control panel and on the other side of the motor is the gearbox connected with the pump rotating part. By changing the HZ via control panel, the directly connected screw pump would change the feeding speed and accordingly the feeding capacity.

OTC Oil Show held in Houston, TX, USA is yearly event for all oil and gas industry. It is one of the 3 largest oil shows all over the world, while the other two are CIPPE held in Beijing, Capital of China, and ADIPEC in Abu Dhabi, UAE. In OTC, you can always see the most advanced technology in oil and gas industry, including drilling and exploring for oil and gas, refinery of crude oil, the environment protection solutions for oil and gas industry and etc.

Before, most of the manufacturers as exhibitors are from USA, the oil and gas technology center, but now, more and more good Chinese companies are coming and attending this oil exhibition to compete with USA suppliers at USA local. GN Solids Control is one of them. Comparing with some other solids control companies in China, GN Solids Control is not a company with long history. Ever since its establishment in year 2007, GN has been setting the international quality standard as its standard for production. GN always believes in Quality First, Price Second. When choosing the material for manufacturing, GN always take into consideration the best material for performance.



In this coming OTC 2016, GN has 2 booths, as below:

GN Solids Control (from China headquarter): booth number Reliant Center 1652-A

GN Solids America (from Houston, USA): Reliant Arena 9732

Time of Exhibition: From 2nd to 5th, May, 2016

Location: Houston, Texas, USA.

What will GN show for this exhibition?

  1. high speed decanter centrifuge, it could be used as: a. solids control decanter centrifuge, b. decanter centrifuge after V-G dryer or high-G shaker for treating the drilling cuttings. c. dewatering centrifuge to be used together with dewatering unit, for treating the drilling mud.
  2. high speed V-G dryer to treat the drilling cuttings from the solids control system, for OBM and SBM.
  3. high-G drying shaker, with 4 pcs of screens and play a role as first step of treatment for drilling cuttings of WBM. This similar shaker could also be changed into shale shaker for solids control systems.

If you have plan for OTC 2016 and would like to talk with GN, welcome to send email to for appointment.

GN bIg bowl centrifuge


Among all the solids control equipment, the shale shaker and the desander or desilter cones are of less technology. The quality for the shale shakers always depends on the designed structure, the material choosing and the welding standards, like if there are bubbles in the welding seam. In fact, in the first year of operation, a well made shale shaker and a poorly made one are nearly the same with each other. But when they are used longer than one year, the problems start to show. In a word, the shale shakers’ technology is not so complicated.

Comparing with the shale shaker and mud cleaner (which could be divided to desander cones and desilter cones), the decanter centrifuge shows a manufacturer’s producing capability to the most. Because:

  1. there are many rotating parts in the decanter centrifuge, the producing accuracy is very important to the rotating part. And the producing accuracy comes from the advanced producing machines and professional operators and workers. GN Solids Control, as the number 1 solids control and waste management centrifuge manufacturer, is also the first one in this field to invite the five face producing machine for the centrifuge parts manufacturing in order to ensure the accuracy.
  2. the decanter centrifuge is of highly speed and the most welcome speed for waste management centrifuge is 3200RPM. Although many manufacturers claim that their centrifuges could reach high speed up to 3200RPM, but seldom could ensure the noise and vibration during high speed. GN Solids Control’s centrifuges are under precise test and producing and each one was strictly inspected before delivery. So GN’s high speed centrifuge is really high speed performance one.
  3. a suitable length and diameter ratio. Normally it is 3, and 3 is the most suitable ratio for the waste management centrifuges. For the solids control ones for treating the HGS, the middle speed and 2 of length diameter ratio is enough. And also how long is the cone part affect the treating performance.

Pls consult GN for more information.

In order to help preventing the drilling cuttings from polluting the land and water, and also to match the clients’ requests to minimum the cost, GN has successfully designed and manufactured several solutions of waste management systems for safely and economically discharge the drilling cuttings, and those designs have won the acceptances and good feedbacks from the clients.


Per different conditions, GN has designed 2 optional standard solutions:

  1. GNDC40A. it combines the vertical cuttings dryer GNCD930 and high speed decanter centrifuge GNLW363CG, or GNLW363CG-VFD, it fits for both OBM and WBM drilling cuttings. It has a compact structure but there is no storage tank for receiving the clean drilling fluids from the centrifuge. Because this design is suitable for being used alongside the drilling rig, the liquid goes directly from the high positioned centrifuge to the solids control’s storage tank.
  2. GNCD40B is another standard solution for the complete drilling cuttings waste management systems. If the equipment is disassembled from the tanks, the whole system could be transported in a container and easily shipped by sea. Comparing with GNDC40A, this 40B system has a larger storage tank and always used for treating the drilling cuttings separately from the drilling rig jobsite.


If per your jobsite layout or requested functions, they are not so satisfying for you, you could choose GN waste management modules, including GNZS594HGE-LD drying shaker, GNCD930 vertical cuttings dryer and GNLW363CG-VFD decanter centrifuge, and several equipments for optional for transporting the drilling cuttings including the screw conveyor, the submersible slurry pump, the vacuum pump or the diagram pump. In this way, you can choose your own equipments and position them at any place for your project. During the procedure, you can easily choose to stop or start any of them.
