The DiSep^® slurry separation system consists of multiple separation modules, the number and size of which depend on the amount of slurry being processed, and the modules are integrated and mounted on a skid. During separation, the oil slurry passes through the electric field in the separation module, so that the catalyst fine powder is adsorbed by the filler to achieve an efficient separation effect. During backwashing, the separation module is powered off, the electric field disappears, and the backwash oil enters the separation module, taking away the adsorbed catalyst fines. After the separation capacity is reset, the separation module can be energized again to separate the fine powder of the oil slurry catalyst. With proper process control, the separation and backwash processes are automatically switched and cycled. The backwash oil usually uses the raw materials of the catalytic cracking unit, refinery oil, coking wax oil and other media, and returns to the riser reactor or coking unit after backwashing, which effectively reduces the backwash cost.

The DiSep^® slurry separation system consists of multiple separation modules, the size and number of which are determined by the volume of slurry being processed. These modules are integrated and mounted on a skid for ease of operation. During separation, the oil slurry passes through an electric field within the separation module, where catalyst fine powder is efficiently adsorbed by the filler material, achieving a high separation efficiency.

When backwashing, the system powers off, causing the electric field to dissipate. The backwash oil then enters the separation module, flushing away the adsorbed catalyst fines. Once the module’s separation capacity is restored, it can be re-energized to resume the separation of fine oil slurry catalyst particles. With the appropriate process controls in place, the system automatically cycles between separation and backwash modes.

Backwash oil typically consists of raw materials from catalytic cracking units, refinery oil, or coking wax oil. After backwashing, it is returned to the riser reactor or coking unit, which significantly reduces backwash costs and enhances operational efficiency.
