Abstract

An oil slurry filtration system and an oil slurry filtration method, at least one filter is arranged in the filter unit of the oil slurry filtration system, and an oil slurry inlet pipeline, a filtered oil outlet pipeline and a filter residue discharge line respectively communicated with each filter pipeline, and a non-pinhole filter bag of flexible filter material is set in the filter. In the oil slurry filtering method, the oil slurry enters the filter through an oil slurry inlet pipeline connected with the filter for filtering, and the filtered oil is drawn out from the filtered oil outlet pipeline. By adopting the oil slurry filtering system and filtering method provided by the present invention, the long-term stable operation of the oil slurry filtering process solves the problems that the filter material is easily blocked by high-viscosity colloidal impurities, poor regeneration efficiency and low removal efficiency.

Description

technical field [0001] The invention relates to an oil slurry filtering system and an oil slurry filtering method. Background technique [0002] Catalytic cracking is an important process technology for lightening heavy oil to produce gasoline and diesel, and it is one of the most important and widely used technologies in the field of oil refining. Residual oil or wax oil mixed with refining residual oil is used as raw material, and the yield of oil slurry is relatively high, generally about 5%, and even 8% in high yield. The oil slurry is rich in polycyclic aromatic hydrocarbons, which can be used as raw materials for the production of ship fuel or carbon black, carbon fiber, etc., but because the oil slurry contains about 1-6g / L of catalytic cracking catalyst particles, it cannot be used for the production of ship fuel or carbon fiber. The raw material indicators of carbon black and carbon fiber are required, so the current utilization value is low. [0003] In order to ...
