Decanter centrifuge is one of GN’s main products that widely used in all kinds of drilling mud recycling and waste management. This week, GN just finished the fabrication of the variable speed decanter centrifuge ordered by an India drilling contractor.

Almost all the drilling contractors request the equipment used on oilfield to be explosion proof certified for safety consideration. To meet the customers’ requirement on explosion proof standard, GN is now able to provide equipment with motors and control panel certified by China national explosion proof CNEX, IEC Ex and ATEX.

The ordered decanter centrifuge is GN’s model GNLW363C-VFD. The bowl diameter is 14 inch (360mm), bowl length and diameter ratio is around 3, which explains the model of the centrifuge. GN’s 14 inch decanter centrifuge can be used for various purposes due to the VFD design. The typical working speed of this model is 3200RPM, at this speed, the fine solids with size down to 2-5 microns could be separated out without adding additional chemicals. By reducing the speed to around 2000RPM, this unit can be used for barite recovery in solids control system.

The bowl material of this unit is duplex stainless steel 2304 which is much better than SS316L. The centrifugal casting technic makes the bow material has a better distribution feature for better balance.

This unit is equipped with temperature sensor at both bearing seats to inspect the temperature of the bearing. And a vibration sensor is installed on the base for abnormal vibration. All the sensors are used to collect information of centrifuge running and send signal to the VFD control panel. By uploading program into the VFD panel, the panel could monitor the centrifuge and trip off the unit for protection.

The VFD control panel matched to the centrifuge has 3 VFDs for main and back motors of the centrifuge and the feeding pump. Operators could set the running parameters on the HMI screen to adjusting the centrifuge running condition. GN’s VFD panel is positive pressurized explosion proof method, together with the air conditioner, the VFD panel could be used in hazardous are with very high ambient temperature.

Both the decanter centrifuge and control panel are made by GN self. For more information on GN’s decanter centrifuge and other mud recycling equipment, please feel free to contact with GN.

GN vertical dehumidifier uses centrifugal force to drain oil-based or synthetic-based drill cuttings. Stainless steel nets separate the “wet” solids and accelerate them to 900rpm. with G power of 420 G or super high speed of 1200 rpm. / min with a G force of 750 G. Liquid is passed through a hole in the grid, while “dry” solids are extracted using an angled flight attached to a cone that rotate somewhat slower than a rotor. The scraper is protected by a coating with carbide tungsten of abrasive solids and provides a long service life. This helps in keeping a constant gap between the scraper and the mesh, which is crucial for proper operation.

For waste management,normally client will use centrifuge together with vertical cutting dryer

In the past, CIPPE 2018 in March of this year, GN Solid Management, showed an installation to install an oil sludge set to 1 set. This unit has all the necessary functional device for extracting oil from the oil sludge; it can be used in a small-scale oil sludge purification system or as a demonstration device for the user to check if the GN solution can solve the problem of oil sludge disposal. Many visitors to the GN booth have shown their interest in trying this equipment. One of the visitors contacted GN several days after the show and placed an order for this system. This sludge treatment unit consists of a pre-mix procedure, two-phase separation and three-phase separation. The main technologies used are flushing flushing for demulsifying and separating oil for different phases, such as oil, water and solids. The goal is to recover as much oil as possible and to get as little waste as possible.

Customer feedback suggests that the treatment of waste sludge, installed at GN, provides an effective solution for treating waste oil sludge in a well at the place of its installation. They are considering the possibility of starting further cooperation with GN by placing an order for a GN-type sludge treatment system with a large processing capacity.

The pre-mix procedure applies a pre-mix tank with a heat system, as well as a chemical dosing system. Oil sludge must be with a certain liquidity for easy transportation and mixing with chemicals.

The GN Mini Shale shaker GNZS752 and the 9-inch GNLW224 decantation centrifuge are basic equipment used in two-phase separation mode, this is the main GN product that has been approved with good performance and quality. sludge.

The images here show oil, water and solids discharged from the three-phase separation process. In this step, a disk centrifuge is used to receive the liquid discharged from the decantation centrifuge. When operating at high speeds, a disk centrifuge can effectively recover the oil from the slurry. GN can provide a larger capacity sludge treatment system to help the customer recover the oil and get more benefits. For more information, please feel free to contact GN

GN Solids Control is a manufacturer of solid-liquid separation equipment and waste mud environmental treatment equipment, and can provide various qualification certification and quality certification equipment worldwide. It has been exported to more than 70 countries and regions, and its products are distributed in many mud treatment construction sites around the world. Some parts of the GN Solids Control waste mud treatment system are: 1. Dry sieve. 2. Centrifuge. 3. Flocculation and drug treatment equipment. 4. Mud conveying equipment. 5. Mud mixing module. 6.

This paper mainly introduces flocculation and dosing module system.

GN Solids Control GNDU2000R Series The 20-foot-box flocculation dosing system is automatically equipped with a chemical flocculant to assist the decanter centrifuge to separate fine particles from the mud, resulting in relatively clean water for wastewater reuse. Or used for sludge separation, separation of oil and cement and other fine particle separation needs.

By using the GN Solids Control GNDU2000R series of 20-foot containerized flocculation dosing system with GN Solids Control high-speed variable frequency decanter centrifuge, the ultra-fine particles in water-based drilling mud can be separated to meet the requirements of recycled water. For waste mud treatment systems, the Crown Flocculation dosing system is especially important to help the centrifuge process the mud to be clean and to reduce the generation of drilling waste. Thereby reducing the overall disposal cost of the post-disposal slurry.

Description of the operation of the GN Solids Control PAM automatic flocculation dosing system:

During the automatic dispensing of the medicament, the operator adds the medicament to the medicament configuration box. After starting the system, the medicament is mixed with water and first enters the stirring solvent tank, where it is thoroughly stirred and mixed by the agitator; After the box is full, it will overflow to the ripening solvent tank, and then mix and mix again here; after the ripening solvent tank is full, it will overflow to the drug storage box, and the configured liquid can be added. The medicine pump is put into the dosing point, and the fine particles are flocculated to accelerate the precipitation to maximize the solid discharge in the waste mud.
