FHD Decanter Centrifuge Introduction in brief.

With the increase in the difficulty of oil drilling development, more and more oil-based mud will be used in drilling, but during the use of oil-based mud, oily drill cuttings will be generated, which will cause great harm to the environment. And most countries in the world have strict limitations on the discharge of oily drill cuttings. Depending on the region and country, the oil content requirements for drill cuttings after treatment are different, usually less than 5%, and many developed countries and regions require even lower OOC oil content. as a waste treatment solution, The GN Solids Control drill cuttings dryer usually reduces the oil content of drill cuttings to 3-5%.

After GN Solids Control drill cuttings drying system treatment, the total amount of waste drill cuttings can be reduced, and the useful drilling fluid can be recovered for continued drilling. The solid phase material discharged can be sent to a hazardous waste treatment plant for further pyrolysis or biodegradation detoxification.

The role of the oil-based drill cuttings dryer and centrifuge system is to reduce the volume of drilling waste, recover useful drilling fluid, reduce transportation costs and post-processing costs. Its main configuration is as follows:

1. GN Solids Control vertical cuttings dryer GNCD930G

The drill cuttings dryer uses the centrifugal force generated by mechanical rotation to separate solid-liquid mixtures. It can recover the liquid phase in the drill cuttings. The drill cuttings enter through the feed port and enter the space between the screen basket and the screw through the distributor plate. The drill cuttings dryer rotates at up to 900RPM with a separation factor of 420G. Under the centrifugal force, the liquid phase and small particles (centrifugal fluid) pass through the material layer, pass through the screen basket, and flow along the upper cover into the liquid collection trough at the upper part of the machine base, then is discharged out of the machine through the liquid discharge pipe located on both sides of the machine base; the solid part of the drill cuttings remains inside the screen basket. Because there is a speed difference between the rotor scraper and the screen basket, the rotor scraper scrapes the drill cuttings off the screen basket and pushes them to the bottom of the screen basket, thereby discharging the dehydrated drill cuttings into the receiving funnel below the machine or the bottom screw conveyor. This dehydrating process is carried out continuously and can be used for sustainable work. It can be applied for real-time treatment.

2. Decanter centrifuge GNLW363D-VFD

The decanter centrifuge GNLW363D-VFD can further treat the liquid phase separated by the drill cuttings dryer to reduce the density, so that the oil-based mud can be reused. GN Solids Control centrifuges are precision-machined using CNC equipment, with high machining accuracy and good consistency. All major rotating parts are processed by high-precision CNC equipment, and the centrifuges are balanced three times, including the main rotating component 1800RPM medium-speed dynamic balance, screw rotor actual working speed high-speed dynamic balance, and overall dynamic balance, to ensure stable operation of the centrifuge under high-speed conditions.

If you have any questions about drilling mud non-landing (water-based and oil-based), please feel free to call GN Solids Control.

6. Centrifugal pump

 GN Solids Control centrifugal pump components can be replaced with Mishen sand pump components. To extend the service life of the centrifugal sand pump, GN Solids Control centrifugal pump uses nodular cast iron alloy as the pump housing, which has high wear resistance. The impeller of the centrifugal sand pump also uses this material, and high-quality mechanical seals are used to prevent leakage of the centrifugal pump.

Recently, GN Solids Control solid vacuum pump and vacuum degasser passed the factory’s strict inspection and were sold to Chinese drilling companies. The specific models of these equipment are vacuum pump GNSP-40B and degasser GNZS270B. The solid vacuum pump is used as a mud transfer equipment. The vacuum degasser is used as the secondary stage of mud control to remove hydrogen sulfide from the mud. The following is mainly about the advantages of GN Solids Control vacuum degasser.

GNZCQ series drilling fluid vacuum degasser is usually installed after the shaker, which can effectively separate harmful gases existing in the drilling mud, maintain the mud specific gravity, and protect the sand pump and mud pump to improve the processing effect of subsequent equipment. The GNZCQ series vacuum Degasser adopts self-priming mud suction method without additional mud feed pump. The GNZCQ series vacuum Degasser can also play the role of a large mixer to prevent the drilling mud from sedimentation.

GN Solids Control vacuum degasser also has the following characteristics:

1. The vacuum pump sucks the mud into the vacuum tank and uses it to suck the gas out of the vacuum tank. The vacuum pump plays two different roles here. 2. The water ring vacuum pump always operates in isothermal state, suitable for flammable and explosive gas suction, with reliable safety performance. 3. The mud is injected through the rotor window at high speed to break the bubbles in the mud completely, resulting in good degassing effect. 4. The main motor is offset, the machine center of gravity is reduced. 5. Belt drive is adopted to avoid the complication of the gearbox. 6. The application of air-water separator does not cause water and gas to be discharged simultaneously, keeping the exhaust pipe unobstructed. In addition, water can be recycled to the vacuum pump to save water. 7. The suction pipe is inserted into the mud tank, and when the mud is free of gas invasion, it can be used as a high-power mixer.

Last week, GN Solids Control provided a complete mud purification equipment for a New Zealand customer for vacuum excavation mud purification treatment.

The equipment mainly includes mine screen separation device, high-frequency fine vibration screen, desilter , decanter centrifuge, among which:

1. Mining vibration screen

This device is a vibration screen, which mainly separates the large diameter solid particles and has a large processing amount. Because the large diameter solid particles are more wear out of the sieve network, the flexible polyurethane sieve net is used. The sieve of this material has high wear resistance, which improves the continuous operation capacity and work efficiency of the equipment, thereby increasing economic benefits Essence

2. Shale shaker

This device is a fine separation unit, which mainly separates solid particles above 100um. The processing volume is less than the mine equipment, but the screening effect is more. The imported vibration motor is used like a mine sieve to ensure the service life. After the overall heat treatment of the sieve box, the torment strength can reach 8.0g. The bottom frame is made of stainless steel, which is strongly corrosive. It can meet the angle of non -stop operation to adjust the angle of the sieve box, and the operation is more stable.

3. Desilter device

The liquid phase after high-frequency fine screen treatment enters the desilter again, and the solid particles larger than 20-40um can be removed by the desilter. The cyclone of the desilter is made of polyurethane material, which has higher wear resistance.

4. Decanter centrifuge

GN Solids Control centrifuge can separate solid particles larger than 2-5 µm. The centrifugal separators are necessary because the slurry after desliming treatment does not meet the criteria for recycling. Centrifugal separators reduce the specific gravity of the slurry to allow for reuse. The decanter centrifugal are fabricated with bi-directional stainless steel centrifugal casting, which is superior to 304 and 316 materials. The wear-resistant head of the waste discharge port uses a special tungsten carbide hard alloy bushing, which provides excellent wear resistance. The separators are dynamically balanced three times – at medium speed, high speed, and overall – to ensure stable operation under high-speed conditions. Producing products of inferior quality is equivalent to creating waste. GN Solids Control has always adhered to the principles of safety first and top quality, which has allowed it to develop rapidly within the industry.

The screw conveyor supplied this time has the following functions:

1. The cover plate on the top of the spiral is made of steel grating, which is detachable. At the same time, one end is a hinge and the other end is a locking bolt. The cover plate is opened conveniently and quickly.

2. Equipped with a pull switch, when someone opens the cover, the screw will automatically stop. When the pull switch is not reset, the screw cannot be restarted, which has high safety.

3. In order to further improve the safety of the equipment, the electric control box is equipped with an emergency stop switch to realize emergency shutdown.

4. When the screw is started, the sound and light alarm on the electric control box will alarm to remind the surrounding workers that the screw is about to start, and the sound and light alarm time can be adjusted. When the alarm time is up, the spiral will start automatically.

5. There is an obvious safety reminder mark on the spiral, which meets the HSE requirements. At the same time, the electric control of the motor and the spiral equipment are grounded.

6. Spraying system, along both sides of the entire spiral, there are clean water flushing pipelines, with nozzles and valves, so that the spiral can be rinsed without opening the spiral cover to prevent the spiral from clogging.

7. The cover plate of the screw conveyor is designed to prevent collapse to prevent accidents caused by operators stepping on the cover plate by mistake.

The screw conveyor can directly collect the solid waste separated by shales shaker, desilter, desander, decanter centrifuge and other equipment at the drilling site, and transport it to the location where the customer needs to be delivered. It plays an important role in the project that the mud does not fall to the ground.

GN Solid Control, a company specializing in oil sludge treatment, has successfully provided a complete set of oil sludge treatment systems to an environmental client in the Middle East. This system is primarily used for treating oil sludge from drilling platforms, refineries, and the bottoms of oil tanks. Designed specifically for high viscosity and high solids content oil sludge, the GN oil sludge treatment system produces three main products: oil, water, and solids.

Recently, GN Solid Control Company delivered a complete oil sludge treatment system to their environmental client in the Middle East. The system includes the following main components:

Pumping Module:

The core equipment in this module is a vacuum pump. GN’s vacuum pump is an air-powered pneumatic pump. The module includes an air compressor that generates compressed air to power the vacuum pump. The vacuum pump is capable of transporting various materials such as drilling waste, industrial slurry, chemical powders, construction aggregates, oil sludge, and kitchen waste. Its strong conveying capacity makes it excellent for oil sludge transportation, effectively completing the conveying task by delivering the oil sludge to the preliminary screening module.

Preliminary separation Module:

The main equipment in this module is a mining screen. After the materials are crushed by a crusher, they pass through the mining screen for particle separation, separating large solid particles. The separated materials are then transported to the heating and mixing module. GN Solid Control has independently developed and produced various models of mining screens with excellent separation efficiency and long service life.

Heating and Mixing Module:

Due to the high solids content, high viscosity, and poor flowability of the oil sludge material that the client needs to treat, the GN oil sludge treatment system is equipped with a heating and mixing module. The mixing tank is equipped with an agitator to prevent oil sludge precipitation. The mixing tank also has a heating function to improve the fluidity of the material through agitation and heating, facilitating pumping. This module is placed in a 20-foot container.

Fine material separation Module:

The system utilizes the GN GNZS706 dual-deck shale shaker. The upper deck uses a lower mesh number screen, while the lower deck uses a higher API number screen. Multiple screening processes with a large screening area and extended time result in better separation conditions for the decanter centrifuge. The shale shaker uses GN Solid Control’s own production of shaker screen, which comply with the API RP 13C standard.

Decanter Centrifuge Module:

After the oil sludge is screened by the shale shaker, it is pumped into the GN decanter centrifuge for two-phase separation. The separated solid phase has an oil content of ≤5%, while the liquid phase consists mainly of oil and water. The solid phase can undergo further hazardous waste treatment, while the liquid phase is transported to the disc stack separator by a screw pump. The centrifuge model used in this system is the GNLW553D-VFD.

Chemical Dosing Module:

To enhance the separation efficiency of the horizontal screw centrifuge, chemical dosing is typically used. Demulsifiers are used to break up more oil, while flocculants are used to separate more solid residues. The chemical dosing module includes demulsifiers, surfactants, and flocculants for oil sludge treatment.

The oil sludge treatment system designed by GN Solid Control is of great significance for waste treatment as it enables reduction in waste volume while recovering a significant amount of oil. It meets current environmental requirements by achieving energy savings, emission reduction, waste utilization, and efficient recovery.
