Abstract:The stripper in FCCU became more concerned as the FCCU throughput and the heavy fractiongs in crude oil increased. The high efficiency stripping technology could reduce the coke yield of FCC process and the load of regenerator, which is significant in economy. So, many patents about the stripper had been made. In these patents, much modification had been made to the baffle and some new stripper model had been provided. The optimization should be made to the operation conditions of strippers so as to raise the stripping efficiency. Pre-stripping and multi-stage stripping intensify the contact between catalyst and steam so as to raise the stripping efficiency.
Keywords:FCC  stripper  stripping technology  fluidized bed with packing
