2) Linear motion shale shaker and high G drying shaker: GN brand shale shaker has been widely used for oil & gas drilling solids control system, HDD & CBM mud recycling system, water based drilling waste management system.


3) Decanter centrifuge: GN 14inch bowl , 18 inch bowl, 22 inch bowl decanter centrifuge has been used for oil sludge treatment system, drilling waste management system, dewatering unit, solids control system, etc.

If you are looking for a good manufacturer of decanter centrifuge, vertical cuttings dryer, shale shaker, shaker screens, welcome to visit GN solids control stand at CIPPE 2018 to check our equipments.
Our stand info is as below:


We will show our best sold model decanter centrifuge at the show. As the largest and most professional oilfield industry products and service exhibition in China, all of the manufacturers will show their most advanced technology during the show.


GNLW363CG-VFD decanter centrifuge is one of the best sold model for our international clients, it can be used for solids control system, drilling waste management system, industry waste water treatment, dredging slurry separation, dewatering system, barite recovery, Low gravity solids separation, etc.
GNLW553C-VFD decanter centrifuge is the best sold big bowl big volume centrifuge, it is normally used as dewatering centrifuge with chemical dosing system for waste water treatment, it can be used for all kinds of waste water treatment. Sometimes it is used for oil sludge treatment system when the clients need 20~25m3/h treating capacity.


We will also show vertical G dryer GNCD930, it works together with GNLW363CG-VFD decanter centrifuge as drilling cuttings treatment system for oil based mud.
4 panel shale shaker GNZS594E installed with composite material shaker screens, with longer service life and better performance. We produce shaker screens in our own workshop, so GN solids control can control the quality by our own quality control dept. without purchasing from other suppliers. We produce OEM shaker screens for own shaker and replacement shaker screens for US brand shale shaker, like Derrick, Swaco, Brandt, FSI, Kemtron, etc.

As the development of energy industry and also the enhancing demand of environment protection, the oily sludge, or oily waste discharged from the energy industry are being restricted to be disposed directly. The regulations and standards are more and more rigid than before. Now all the players in this field are facing a problem: how to treat the oily sludge efficiently and safely?

GN Solids Control has provided a solution, which is proved to be suitable in both domestic China and abroad. The complete system is combined of several equipment, which serve different applications, including the functions for heating, pre-mixing, reduce the viscosity, separating out the solid particles, leveling the oil and water and finally separate out all of the 3 phases.

GN Oily Sludge Separation SYSTEM
GNOWS series Oil Water Separator is one of the important equipment in an oily sludge separation system. It is located after the GNIPC Inclined Plate Clarifier or a GNLW decanter centrifuge to hold and further treat the liquid phase from forehand equipment, to separate the oil from water.
The working principle is gravity stratification cause by the different density of water and oil. Inlet of this equipment is the waste liquid, while the outlets are 3: the clean oil outlet, the clean water outlet and the gas release ports. Inside the GNOWS oil water separator, there is a detachable coalesce, when the oily wasted water enters the oil water separator and meets the detachable coalesce, the oil and water could be separated. Then the oil enters the oil chamber while the water enters the water chamber. The tank is designed to hold the liquid for a while for a complete separation of the 2 kinds of liquid. Outside the tank, there is a visible level meter, for the operator to observe the inside condition in time.
For this equipment, GN has different models for different treating capacities, please see details in GN website.

GN Solids Control, as the first API certified solids control manufacturer in China and also the leading oil and gas centrifuge producer, has a full range of centrifuge models from the 9 inch diameter bowl baby centrifuge to the 30 inch diameter bowl giant centrifuge. Each year, GN produces more than 150 sets centrifuges of different sizes and GN equipment like shale shakers, shaker screens and decanter centrifuges are sold to more than 70 countries or regions in the world.

About GN Solids Control

GN CENTRIFUGE

GNLW centrifuge jobsite picture

This Q/A are giving more information for choosing and getting a more comprehensive information of GN Centrifuges.
1. Why there are VFD for decanter centrifuge and also fixed speed available?
VFD control panel helps the operators to adjust the speed, the differential speed and other main parameters of centrifuge to get a suitable separating result. In drilling cuttings or drilling fluid waste management conditions, when the material condition is not stable, it is necessary to use a VFD one. But in case of solids control system of a drilling rig, when the mud condition is stable, a fixed speed control panel here is more economic, cause it requests less maintenance and easier operating. Take GNLW363CG for example, even the fixed speed one, GN could provide pulley and belt for an extra common speed.
2. What’s the main difference between the high speed decanter centrifuge and a middle speed decanter centrifuge? The rotating speed of centrifuge determines the cutting point the centrifuge could treat out, for example the GNLW452C decanter centrifuge, with a typical speed at 1800RPM is mainly used in a solids control system for barite recovery, the cutting point is 5 to 7 microns, while the GNLW453C-VFD with a typical speed of 3000RPM, which is a high speed one, cutting point is 2-5 microns.
3. What’s the difference between longer centrifuge and shorter centrifuge? The length diameter ratio is an important factor of a centrifuge. The longer centrifuge is a centrifuge with a larger length diameter ratio. The bigger this value is, the longer time material stays in centrifuge, then the dryer separating result you could get.
