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.

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.

2-phase and 3-phase centrifuge for oil sludge separation

The final step in the oily sludge separation process involves a crucial three-phase separation to oil, water and solids, and there are two primary options available for achieving optimal results, as recommended from the Separation specialist – GN Solids Control.

Option 1: GN Solids Control Two-Phase Decanter Centrifuge + Three-Phase Disc Centrifuge

This option employs a combination of two-phase decanter centrifuge followed by a three-phase disc centrifuge for fine separation. The decanter centrifuge is initially used to separate the bulk solids and liquids, while the disc centrifuge performs the critical three-phase separation, separating oil, water, and solids with high efficiency.

The disc centrifuge offers a significant advantage by achieving cleaner outputs for both oil and water. It is particularly effective in reducing the Base Sediment & Water (BS&W) content in the oil. BS&W is a key parameter in defining the quality of the oil, and the lower the BS&W, the higher the oil quality. With the disc centrifuge, the output oil typically has a BS&W of 2-3%, ensuring higher purity and quality.

The water output from the disc centrifuge ranges from 1000 to 3000 RPM, depending on the specific settings and operational conditions, ensuring that the water is effectively separated from the oil. Additionally, the solids content in the output oil from the disc centrifuge is typically between 1-3%, maintaining the quality and clarity of the oil while efficiently removing contaminants.

Option 2: Three-Phase Decanter Centrifuge

The second option utilizes a single three-phase decanter centrifuge for all three-phase separation. This centrifuge directly separates the oil, water, and solids in one step. It is a simpler, more compact solution, which may be ideal for certain operational setups where space or equipment complexity is a concern.

The three-phase decanter centrifuge is effective in producing the three separate outputs—oil, water, and solids—though the quality of separation may not be as refined as with the combination of a decanter centrifuge and disc centrifuge. This option is suitable for applications where a balance of performance and operational simplicity is desired, but it may not achieve the same level of oil purity as the multi-stage separation process.

Each option offers distinct advantages, and the choice between them depends on factors such as the desired oil quality, operational conditions, and system requirements. Operators can contact GN Solids Control engieers to ask for more suitable solution.
