GN 3-Phase decanter centrifuge for overseas Electrolytic Purification of Copper Application

Based on its major production decanter centrifuge for liquid and solids separation, GN Solids Control develops its application scope from oil and gas drilling, non-oil drilling and trenchless slurry separation, to industry separation.

GN Solids Control with its sister brand GN Separation can covers more and more liquid and solids separation field, such as oil sludge separation decanter centrifuge and disc centrifuge, mining slurry separation decanter centrifuge, chemical industry decanter centrifuge, Ore And Minerals Separation decanter centrifuge, Grinding And Polishing Liquid separation decanter centrifuge, plastic recycling decanter centrifuge, Soda Plant Waste treatment decanter centrifuge,  Pulp & Paper industry waste treatment decanter centrifuge, and so on.

The centrifuge size GN Solids Control & GN Separation making covers sizes from mini size 9 inch, to popular size 14 inch, and big bowl 18 inch, 22 inch and up to the huge bowl 30 inch. There are few manufacturer in the world have the capability to make big bowl centrifuge up to 30 inch. GN Solids Control can make. And for the same bowl diameter centrifuge, GN Solids Control has various models with various design and material standard to cater for different applications. For example, for normal industry and for food industry, the material grade and the grease grade are much different. And even the processing technology various much.

Right now, GN Solids Control is working on a 14 inch decanter centrifuge overseas Electrolytic Purification of Copper Application. The model of the 14 inch centrifuge is GNLWS364, compared with the GNLW363D series, GNLWS364 has a bigger bowl length and diameter ratio up to 4. The centrifuge bowl diameter are both 14 inch, but GNLWS364 is longer in order to suit for the specified applications.

The centrifuge is equipped with VFD control panel, plus PLC smart control and HMI touch screen. The VFD panel cabinet is made from stainless steel with Grinding And Polishing Liquid. All electrical components are choose from top and international famous brand. The VFD drive brands is INOVANCE / ABB. The PLC brand is Siemens or Omron.

Mud Cleaning Package Equipment for slurry separation in New Zealand

GN Solids Control makes various size slurry separation equipment to treat the slurries which is generated from trenchless activities, piling, pipe jacking, super vac activities.

This week, GN Solids Control is working on the assemble and commissioning of a full package slurry separation system. The slurry treatment system is designed and made for a New Zealand client for their super vac excavation slurry. The system is customized with the client’s red color.

Below are the major separation equipment used in the slurry equipment:
The first separation equipment: the mining separation screen separation device for coarse separation.
The second separation equipment is the High Frequency Vibrating Screen for fine solids separator.

The 3rd separation equipment is desilter mud cleaner. 4 inch desilter assembly was used for further clarification. The cut point of 4 inch desilter is 27 microns. It means most of the particles above 27 microns will be removed and discharged from the desilter separator, and falls down to the under flow shale shaker.

The 4th separation equipment is high speed decanter centrifuge. The cut point of high speed decanter centrifuge is 2 ~ 5 microns. The slurry enters into decanter centrifuge already treated by the previous screening separator and the desilter mud cleaner, the solids content is lower, and there is no particles bigger than 30 microns. After treatment of decanter centrifuge, most of the fine solids above 2 microns will be removed.

After some circles of above separation, the ulti-fine solids smaller than 2 microns will be more and more. In order to solve the situation, chemical dosing unit will be applied to used together with high speed decanter centrifuge for dewatering treatment. The chemical dosing unit and the decanter centrifuge used together for lower gravity solids separation.

Screw conveyors are used along with the mud system for carrying the solids waste discharged from the system.

Mud agitator for drilling mud system, frac tank, mixing tank

Drilling mud agitator is a popular equipment in various kind of drilling mud system, includes but not limited to oil and gas drilling, water well drilling, Horizontal directional drilling, and other trenchless underground activies.

Drilling mud agitator is designed for stirring drilling fluids and slurries in open tanks. It is to avoid the solids settle down, and ensure the equal mixture of liquid and solids. It is the necessary process to ensure qualified drilling mud to support drilling activities.

GN Solids Control makes various models drilling mud agitator from motor size 3kw to 22kw. Drilling mud agitator is a relative sample design equipment. The major components of an agitator is driven motor, gearbox reducer, agitator shaft, and impeller. The gearbox reducer is connected to driven motor. The impeller / impellers are installed to rotating shaft, the shaft is connected to gearbox reducer output shaft and rotated with it.

There are 2 kinds of gearbox reducer which are used for drilling mud agitator.
The most popular gearbox reducer is worm gearbox. It is more widely used, as the economic cost.
Another kind of gearbox is helical bevel. It is the heavy duty gearbox with bigger efficiency and reliable performance. And the maintenance is relative easier.

The agitator motor size, shaft length and impeller diameter, impeller quality should be caculated based on below information:
1. The type of the tank: it is rectangular tank or cylindrical tank.
2. The size of the mud tank: Length, width and height of the tank
3. How many agitators are used in the mud tank?
4. The frequency of the driven motor: it is 50 hz or 60hz.
5. The density of the mud. For heavy mud, the agitator size will be bigger size than light mud. Mud agitators for actives tanks may be bigger in size, or more in quality than suction tank and reserve tanks.

Besides drilling mud solids control equipment, GN Solids Control also make centrifugal pump for mud mixing, mud transfer, and suction in drilling mud system.

GN Solids Control Centrifuge at 2023 NEFTEGAZ Russia Oil Exhibition

The Russian International Oil and Gas Exhibition NEFTEGAZI was founded in 1978 and hosted by Expocenter. It is a professional oil exhibition in the Eastern European region and a stage for global suppliers to showcase new oil and gas industry technologies. NEFTEGAZI is held once a year, with an exhibition area of 35000 square meters, over 22820 visitors, and nearly 600 exhibitors. More than 150 exhibitors from China as a national exhibition group participated.

Russia is a major market of GN Solids Control. And GN Solids Control come for NEFTEGAZI every year. This year, GN took his latest design equipment for the exhibition, meet many clients there, and get great success.
Below is the major equipment GN Solids Control took for NEFTEGAZI exhibition:

1. Decanter centrifuge: It is widely used in oil and gas drilling. Normally, there is 2 major applications of decanter centrifuge, and 1 centrifuge is fixed speed control, and another one variable speed control. Firstly, it is used with middle speed in solids control system for high gravity separation. And plus, the decanter centrifuge should be used in the drilling waste management system with high speed for low gravity separation and / or for dewatering treatment.

2. Vertical cuttings dryer. It is the major separation equipment for oil base mud and cuttings. The purpose of the vertical cuttings dryer is to reduce the oil on the cuttings to 3% ~ 5%. With 3% ~ 5% OOC, the solids discharge is easy for shipment, and for next step treatment.

3. Replacement shaker screen. Shale shaker is the basic separation equipment for all kinds of drilling activies, Shaker screen is a major consumable parts of shale shaker especially on oil and gas drilling field. A oil and gas solids control shale shaker need 3 pcs ~ 6 pcs screens per shaker model. There will be 1 shale shaker ~ 4 shale shakers per the size of drilling mud system. In Oil and gas drilling mud system, the screens must be changed every a few days. In some hard drilling section, even every 2 or 3 days. So replacement is a continues and big cost for drilling activities.

GN Solids Control has his own screen plant to make various type replacement screens for most of the popular shaker models. GN Solids Control can also make customized screens per clients request, e.g. with customized sizes, customized color / packing / logo / branding, etc…
