Development of research on high efficiency steam stripping technology for catalytic cracking

The high efficiency steam stripping technology of catalytic cracking unit can efficiently decrease the coke yield, and mitigate the regenerator's load. The method and result of modification made to the traditional annular baffles mentioned in the patents on steam stripping equipment technology at home and abroad is discussed, the designs of some new-model stripping equipment is proposed. It is believed that optimization of the stripping process data is a key factor for improving the stripping efficiency. The prestripping and multi-stage stripping technologies have strengthened the contact of catalyst and water vapor, and improved the stripping efficiency.
