22inch big bowl decanter centrifuges unit for Oil Sludge Treatment Company

A set of oily sludge separation equipment has been completed for a middle east client, designed to treat the oily slurry generated from contaminated soil treatment and oily sludge separation systems. The client faces a challenge in reducing the solid content of the material, which the centrifuge can process, to below 10%, with solid particles smaller than 2 millimeters. Currently, they aim to achieve this without using dilution.

The desilter mud cleaner used in the system is capable of separating particles as small as 30 micrometers. If all particles larger than 30 micrometers are successfully separated, the solid content can be reduced to a certain level, but further steps are necessary to achieve the desired result. Following flocculation, the minimum solid content that can be achieved by using the 4 inch cyclone for separation will depend on the efficiency of the process, as flocculation helps to aggregate fine solids, making them easier to separate.

An important consideration is the oil content in the liquid phase. If the oil content is too low, the three-phase decanter centrifuge becomes ineffective at separating the oil, making it unsuitable for the task. In such cases, only a two-phase centrifuge will be effective.

The equipment setup also includes a desilter mud cleaner, which serves as a pre-separation stage to remove the majority of the solids, reducing the weight of the slurry before it moves into the next treatment stages. After this, two sets of high-speed centrifuges (22-inch big bowl centrifuges) are used in tandem for ultra-fine solids separation. The two centrifuges can process the slurry together to achieve better separation of the fine solids.

Additionally, the system is equipped with a chemical dosing unit that allows the client to treat the slurry in two stages: the first set of centrifuges for fine solids separation and the second set for dewatering treatment. After the centrifuge treatment, an oil-water separator is employed to separate the oil and water phases, completing the treatment process. This setup is designed to provide efficient oily sludge separation while addressing the specific challenges of the middle east client’s materials.

3-phase decanter centrifuge and oil water separator for oil sludge treatment

GN Solids Control is capable to offer complete packages for oily sludge separation, designed to efficiently process and treat contaminated sludge. The core equipment in the system includes shale shakers and decanter centrifuges, which play a vital role in the separation of solids from the liquid phase. GN Solids Control manufactures both 2-phase and 3-phase decanter centrifuges, each suited for different stages of the separation process.

The 2-phase decanter centrifuge is typically used to separate solids from the liquid phase, resulting in two distinct phases: a solid phase and a liquid phase, which typically consists of water and oil. The 2-phase centrifuge is particularly effective in handling high volumes of oily sludge, where the separation of fine solids from the liquid is required. In cases where a more precise separation of oil and water is necessary, GN Solids Control provides a 3-phase decanter centrifuge. The 3-phase centrifuge is designed to simultaneously separate solids, oil, and water into three distinct phases, improving efficiency in applications where both oil and water recovery are critical.

In addition to the decanter centrifuges, GN Solids Control offers an oil-water separator, which can be used following the 2-phase centrifuge separation. The oil-water separator is an effective solution for further separating the oil and water phases, ensuring a cleaner and more purified liquid phase. This equipment is particularly useful when the oil content in the liquid phase is too low for the 3-phase centrifuge to operate effectively, allowing for a more tailored approach to the separation process.

Together, these components form a comprehensive oily sludge separation system that can be customized to meet the specific needs of the client. GN Solids Control’s equipment is designed to optimize the separation process, improve recovery rates, and ensure the treatment of oily sludge is carried out efficiently and effectively. Whether using a 2-phase or 3-phase decanter centrifuge, or utilizing an oil-water separator for additional separation, GN Solids Control provides robust and reliable solutions for oily sludge treatment.

How to choose the flush pump for decanter centrifuge?

When it comes to choosing a flush pump for a decanter centrifuge, numerous users often have the same question: Can the existing sludge feeding pump double as a flushing pump? Specifically, many consider the idea of adding a water line to the suction area of the current feed pump for this purpose. The proposed process entails closing the sludge valve and opening the water valve to initiate the flushing action. Nevertheless, grasping the correct configuration is crucial to guarantee top-notch performance.

GN Solids Control suggests employing the centrifuge’s feeding screw pump as the flush pump. This recommendation offers both economic advantages and operational efficiency. To put it into practice, a T-piece needs to be inserted into the suction pipe of the feeding pump and then connected to a dedicated water line. Through separate valves, operators can control the water line and the slurry feeding pipe independently, enabling seamless transitions between the feeding and flushing modes.

By leveraging the feeding screw pump for flushing, operators can enjoy dual functionality, eliminating the necessity for an additional, stand-alone flush pump. This setup streamlines the overall system and brings an extra perk: the water line can effectively flush and cleanse the settled solids within both the screw pump and the feeding pipelines. As a result, the entire system stays clean, averting blockages and ensuring the decanter centrifuge operates continuously and efficiently.

In general, if the aforementioned setup is properly implemented, a separate flushing pump usually isn’t required. However, in cases where unique operational circumstances demand more flushing power or a particular pump configuration, considering a separate flushing pump could be a viable option, like screw pump, centrigugal pump, surry pump, etc…

To sum it up, GN Solids Control’s recommended practice of using the feeding screw pump for flushing represents an effective solution. It boosts system efficiency, cuts down on equipment requirements, and keeps the centrifuge in prime working condition. This approach mirrors GN Solids Control’s dedication to supplying high-quality, cost-effective solutions for solids control and waste management across diverse industries.
