GN Solids Control is one of the leading brands for solids control and waste management system, and second to none ranks among Chinese manufacturers in this industry. A lot of worldwide famous oil companies and oil drilling companies are using GN equipment and comprehensive solutions, including SINOPEC, CNPC and COSL. Recently, GN delivered main equipment for 2 sets of drilling cuttings waste management systems for CNPC.

GN BIG BOWL CENTRIFUGE FOR CNPC

Drilling cuttings are solids discharge from the drilling rig solids controls system, from the shakers, desander and desilters. After the solids control system’s first 3 phases separating, the drilling fluids are returned back to the system without the solids particle. But the separated-out particles are still too wet. For one thing, it is a waste for valuable drilling fluid. Secondly, it could damage to the environment if disposed directly. That’s why it is not only necessary but also mandatory to do some further treatment for the drilling cuttings.
GN Solids Control has zero discharge solutions for both WBM and OBM. And this order, combining the vertical cuttings dryer and decanter centrifuge, is for the oil based mud. A vertical cuttings dryer is specially designed for the oil based mud separation. GNCD930 series vertical cuttings dryers could dry the drilling cuttings to reach OOC value to 5%. The vertical cuttings dryer is running as the drying step of a washing machine. The vertical cuttings dryer is equipped with a screen basket with certain mesh number. Fluids pass the mesh and collected, while cuttings are stopped by mesh and falls down.
GNLW series decanter centrifuges with VFD control panels are used after the vertical cuttings dryer to remove the particles from 2 to 5 microns from the liquid. Most common model is GNLW363CG-VFD, a medium sized centrifuge with a high rotating speed. But for bigger treating capacity, GN has GNLW453C-VFD and GNLW553-VFD available, both of high rotating speed while bowl sizes are respectively 18 inch and 22 inch. In this project, clients chose GNLW453C-VFD.
Pls contact GN for more information.

Recently, GN has produced for 2 different clients who worked for similar projects, with following equipment and solutions:
1. GN big bowl 22 inch diameter decanter centrifuges.
2. GN chemical dosing unit
3. GN standard containers.

GN CONTAINERIZED CENTRIFUGE AND DEWATERING

GN has been providing this design for many years, and the technology is quite mature:
1. GNDU2000 Chemical dosing unit. GN has been providing the chemical dosing unit or so called the dewatering unit for many years, since some of GN clients are using GN centrifuges as dewatering centrifuges and prefer GN to make compact design for them. A chemical dosing unit is used to treat the material by some chemical methods, for example, to add some material to reduce the viscosity of material, or to flocculate the extra fine particles into larger ones, which are suitable for centrifuge use.
2. GNLW553C-VFD decanter centrifuge is a big bowl decanter centrifuge with a treating capacity up t to 90 cbm per hour, and the rotating speed could reach 3000 rpm. It is quite suitable for drilling liquid management, especially being used together with chemical dosing system. Normally, the centrifuge treating capacity for material after flocculation would be greatly reduced, that’s why a big bowl centrifuge with a large treating capacity is always used for this application.
3. 20 ft containers for housing the centrifuge and chemical dosing system, which is quite popular design. For one thing, it is more convenient and easy to transport the system when the main equipment are in standard containers. Secondly, the containers give a shield to the equipment, providing a suitable temperature and clean condition. Thirdly, the 2 sets of 20 ft containers could be put one under another, in this way, less room to be occupied.
In this design, GN engineers designed the round shaped ladders for the upper located container with the big bowl decanter centrifuge, when transporting, the ladder could be put into the container.

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.
