The T series GN Decanter Centrifuge is the dewatering type of centrifuge.  It ranges from 9in to 30in bowl. A dewatering centrifuge is a specialized type of centrifuge used for separating solids from liquids in a slurry or suspension. The primary purpose of a dewatering centrifuge is to remove water or liquid content from solid materials, leaving behind a drier substance. This process is commonly used in various industries such as wastewater treatment, mining, food processing, and chemical manufacturing. Also in drilling mud, environmental protection sewage, oily sludge, chip fluid, sand washing water, mineral water, soda white mud, and salt mud dewatering. It has a drive type of VFD, PLC, and HMI. It is made up of stainless steel ss2205 and ss316. For wear protection it has tungsten carbide tiles. The way it works is, the slurry or suspension containing solids and liquid is introduced into the rotating drum or bowl of the centrifuge. The drum of the centrifuge rotates rapidly, creating centrifugal force. This force causes the heavier solid particles to move outward and settle against the inner wall of the drum. The centrifugal force separates the slurry into two phases: a denser solid phase that accumulates near the drum’s inner wall and a lighter liquid phase that remains closer to the center. As the drum continues to rotate, the separated solid phase experiences further compression, aiding in the removal of additional liquid. The dewatered solids form a cake along the inner surface of the drum. Once the dewatering process is complete, the separated liquid is discharged from the centrifuge, and the dewatered solids (cake) are typically removed manually or through automated mechanisms. Dewatering centrifuges find applications in various industries where the separation of solids and liquids is crucial for environmental compliance, product quality, or process efficiency. They are especially common in wastewater treatment plants, mining operations, and industries dealing with high-volume liquid-solid separation processes. It decreases the waste and separates the liquids, some product was water so pure that it can be released back to nature or to be reused in the operation. GN centrifuges are one of the best equipment when comparing to the ones three times of its cost.

A mud cleaner, also known as a desilter or desander, is a piece of equipment used in the oil and gas drilling industry to separate solids from drilling fluid.

A submersible slurry pump is a type of pump designed to handle abrasive and high-density slurries. Slurry pumps are used in various industries, such as mining, dredging, construction, and wastewater treatment, where there is a need to pump a mixture of solid particles and liquids. At GN we have ten different sizes of our submersible slurry pumps. From 10m height to 24m height, different flow capacity and outlet diameter. These pumps are designed to be submerged in the fluid they are pumping. This design is beneficial for applications where the pump needs to be placed directly in the slurry or fluid. Submersible slurry pumps are specifically engineered to handle slurries with a high concentration of abrasive solids. They are equipped with robust impellers and wear-resistant materials to withstand the abrasive nature of the pumped material. The pump is enclosed in a sealed housing to prevent water or other fluids from entering the motor or other critical components. This submersible design also enhances safety and minimizes the risk of leaks. These pumps are built with heavy-duty materials and construction to withstand the harsh conditions associated with pumping abrasive slurries. Materials such as high-chrome alloys are often used for wear parts. Some submersible slurry pumps offer variable speed controls and features for adjusting the agitating force. This allows operators to optimize performance based on the specific characteristics of the slurry being pumped. The design of these pumps aims to maximize efficiency in pumping slurries, ensuring that a high percentage of the input power is converted into useful work. Submersible slurry pumps find applications in various industries, including mining (for transporting tailings and mineral processing slurries), dredging (for moving sediment and dredged materials), and wastewater treatment (for handling sludge and abrasive wastewater). It’s important to note that the selection of a submersible slurry pump should be based on factors such as the type of slurry, particle size, flow rate, and the specific requirements of the application. Proper maintenance is also crucial to ensure the longevity and efficiency of the pump in handling challenging slurry conditions. The slurry pump is the ideal centrifugal pump for feeding to decanter centrifuge, and feeding from mud pit for to the shale shakers on the mud systems, and desander or desilter.

Desander in solids control is a crucial component in the process of drilling fluids management within the oil and gas industry. Its primary purpose is to remove solid particles, such as sand and silt, from drilling fluids to maintain the desired properties of the fluid and enhance the efficiency of drilling operations. The main function of a desander is to separate and remove larger solid particles, typically ranging from 40 to 100 microns, from the drilling fluid. By removing these solids, the desander helps maintain the rheological properties and stability of the drilling fluid, ensuring it can effectively carry cuttings to the surface. The core component of a desander is a set of hydrocyclones arranged in a manifold. These cyclones use centrifugal force to separate solid particles from the drilling fluid. Drilling fluid containing solids enters the desander through an inlet pipe, and the cleaned fluid exits through an outlet pipe. The separated solids are discharged through the underflow port, while the cleaned drilling fluid exits through the overflow port. Drilling fluid, often called mud, enters the desander unit at high pressure through the inlet. The hydrocyclones in the desander create a swirling motion, causing heavier solid particles to move toward the outer wall and exit through the underflow port. The cleaned drilling fluid, with reduced solid content, exits through the overflow port. Desander solids control is typically part of a larger solids control system that includes other equipment like shale shakers, desilters, and centrifuges. These components work together to ensure the drilling fluid meets specified criteria for reuse in the drilling process. By maintaining the quality of the drilling fluid, desander solids control contributes to efficient drilling operations. Removing abrasive solids helps protect downstream equipment, such as pumps and mud motors, from wear and damage. Regular maintenance is essential to ensure the proper functioning of desander solids control equipment. This includes monitoring and cleaning the cyclones and checking for any wear and tear. Desanders play a crucial role in the overall solids control process, helping to enhance the efficiency and cost-effectiveness of drilling operations in the oil and gas industry. At GN we provide our customers with customized desanders, according to their functions and operations. We can attach them to shale shaker, and with desilters or by it self. Keeping your operations running sound and well.

A desilter is a device used in the oil and gas industry to remove fine particles (usually sand and silt) from drilling fluids. Drilling fluids, also known as mud, are essential in the drilling process as they help cool and lubricate the drill bit, carry cuttings to the surface, and provide stability to the wellbore. Desilters are part of a larger system called a solids control system, which is designed to separate and remove solids of various sizes from the drilling fluid. The desilter specifically targets smaller particles, typically in the range of 15 to 44 microns. It follows the larger solids removal equipment called desanders, which focus on particles in the range of 50 to 70 microns. The desilter typically consists of a set of hydrocyclones, which are cone-shaped devices that use centrifugal force to separate solids from the drilling fluid. The clean fluid is then returned to the drilling process, while the separated solids are usually discarded or treated for disposal. Efficient solids control is crucial in drilling operations to maintain drilling fluid properties, prevent equipment wear, and enhance overall drilling efficiency. Desilters play a specific role in this process by targeting the removal of fine particles from the drilling fluid. GN desilter is the third class solids control equipment to treat the drilling fluids. According to the size of the cone diameter, they are divided into Desander and Desilter. Usually the cone diameter is less than 6″is called Desilter, and used as the third-control equipment in drilling operation. We commonly used 5 “and 4” cone to separate solid-phase particle size 15-47μm in the drilling fluid. Based on customer requirements and capacity, we can select groups of cone into Desilter.GN Desilter works very well with Solids control system other equipments. The GN Mini Mud Cleaner is innovative products for drilling fluids cleaning. The traditional desander desitler without Shale Shaker is only available for unweighted drilling mud.The traditional mud cleaner is oversized for some applications,and the mud cleaner is relatively more expensive. The innovative GN Mini cleaner is an ideal option for both weighted and unweighted drilling mud with the most cost effective solution for drilling. Further more, the GN Mini Cleaner is the best choices for small mud system for HDD,CBM, water well drilling, mining exploration industry etc. Usually a second phase for your operation, but according to your needs and how your operation is planned, you can use desilter at any point and have it recycled process to get the product processed. GN desilter by itself or attached with other equipment, it will process your product with ease and makes your operation to be executed with ease.

A centrifugal pump is a type of pump that uses the kinetic energy of a rotating impeller to move fluid. It’s one of the most common types of pumps and is widely used in various industries for transporting liquids. GN SB series Centrifugal Pump is used to transfer drilling mud. It can be used as feeding pump for desander, desilter, or used as a mixing pump for Jet Mud Mixer. It can also be used as a trip pump, and supercharging pump for a rig mud pump. All GN model centrifugal pump use tungsten carbide mechanical seal, with famous brand Bearing. Spare parts interchangeable with most of the international Brand pump which helps customer to source spare parts easily. Open impeller design allows lowers axial thrust loads. It makes it easier for installation, repair and maintenance. A centrifugal pump is a type of pump that uses the kinetic energy of a rotating impeller to move fluid. It’s one of the most common types of pumps and is widely used in various industries for transporting liquids. The key component of a centrifugal pump is the impeller, which is a rotating disk with curved blades. The impeller is typically mounted on a shaft that connects to a motor or another power source. The impeller is housed in a casing that contains the liquid. The casing is designed to gradually expand in diameter as it approaches the outlet, creating a volute shape. Operation: When the impeller rotates, it imparts kinetic energy to the liquid, causing it to move radially outward. As the liquid moves through the impeller, it also gains velocity. The rotation of the impeller generates centrifugal force, which creates a low-pressure area at the center of the impeller. This low pressure draws more liquid into the impeller. The volute casing helps convert the high-speed, low-pressure liquid exiting the impeller into high-pressure fluid. It does this by slowing down the flow and converting velocity energy into pressure energy. The pressurized fluid is then discharged through the pump outlet. Centrifugal pumps are preferred for their simplicity, efficiency, and versatility. They are commonly used in water supply systems, wastewater treatment, irrigation, chemical processing, petroleum refining, and many other applications where the transport of liquids is required. There are various types of centrifugal pumps, including single-stage pumps and multi-stage pumps, each suited to different applications based on factors such as flow rate and head (pressure) requirements.

While our function of  solids and liquid separation is really easy to say  but in the background there are a lot of factors that are going on and we don’t see them or hear about them much. As one of them is the Mud Gas Separator. It not only takes out the gases from your mud or slurry but also removes the toxic gas that could harm one. It is designed for continued drilling in underbalanced conditions where dramatic pressure surges normally. Our GN Mud Gas Separator is manufactured according to API and ISO standards. While not just improving the production of the product flow and assisting the process to work better. It saves time and funds due to providing the material to be processed without additional gases that could slow the process. The gas cut mud enters the flow line of unit, where it hits a series of baffle plates. These plates provide surface area for the dispersion of the gas cut mud. This routed mud to solids control equipment for further processing, meanwhile the separated gas travels to the flare line at top of unit to vented safely  from the rig. There are a few different types of mud gas separators, Today we are talking about a “poor boy separator”, it is really simple but unique and effective. Our model GNZYQ1000A is 1000m in diameter.

They are machine operated and require a current of electricity for operation to be functional.  They are very different in sizes and dimensions, but have same function. Yet they are placed in different area of process control.  Our products assist not just with better functionality but also safety of the operations. At GN Solids we manufacture the best product with different variety and above all, our pricing is unbeatable.  

When it comes to selecting decanter centrifuge models for wastewater treatment and oil sludge processing through three-phase separation, a test tube centrifuge is an invaluable tool for determining the most suitable centrifuge model. This method follows a specific procedure as following steps:

The customer is instructed to set the separation factor of lab tube centrifuge to 1200G for a duration of 2 minutes. If clear layering is observed during this process, it indicates that the centrifuge possesses excellent separation capability. However, if clear layering is not evident at 1200G, the setting is increased to 2000G for an additional 2 minutes. If clear layering is achieved at this stage, it suggests that a high speed centrifuge can also achieve effective separation.

The test tube centrifuge method plays a critical role in the selection process as it allows for a preliminary assessment of the centrifuge’s separation capabilities. By gradually increasing the separation factor and observing the clarity of the layers formed, it becomes possible to determine the optimal centrifuge model for wastewater treatment and oil sludge processing.

Clear layering is a vital indicator of a centrifuge’s ability to effectively separate the different phases present in wastewater and oil sludge. The presence of clear layering signifies that the solid particles have been successfully separated from the liquid phase, resulting in distinct layers. This separation is crucial for efficient treatment and processing, as it enables the removal of contaminants and facilitates the recovery of valuable resources.

However, if the centrifuge fails to achieve clear layering even at higher separation factors like 2500G or 3000G, it indicates that the separation efficiency may be compromised. In such cases, it becomes necessary to consider alternative separation methods beyond centrifugation.

In conclusion, the test tube centrifuge method is an essential step in the selection of centrifuge models for wastewater treatment and oil sludge processing. By gradually increasing the separation factor and observing the clarity of the layers formed, it becomes possible to determine the centrifuge’s separation capabilities. Clear layering indicates effective separation, while the absence of clear layering suggests the need for alternative separation methods. This careful selection process ensures the optimal choice of centrifuge models for efficient wastewater treatment and oil sludge processing.
