Emergency treatment plan for hot spots and hidden dangers in the wall of oil refining catalytic reverser
In the fourth cycle of operation,the refining unit of a petrochemical company successively appeared hot spots and hidden dangers such as double-acting slide valve wall,external heat extractor wall,semi-re-inclined pipe,and CRC gas return line.In order to en-sure the safety and controllability of the above hidden dangers,according to the structure and process operation conditions of different hot spots,the external stickers,pour the insula-tion linings,and"package boxes"of the device wall have been formulated to strengthen the strength and wear resistance of the wall at the hot spots,and ensure the long-term safe oper-ation of the anti-regeneration system equipment.The treatment process of high temperature,easy wear and leakage hot spots mentioned in this paper has a good reference significance for petrochemical enterprises.
