Abstract: To extend the life cycle of VRDS unit, measures were proposed by RIPP base on the analysis of factors affecting the VRDS operation. Catalysts with higher activity and stability as well as better grading catalyst filling technology for varies feedstocks are developed. The higher efficient fluid distribution technology and an asymmetric switching guard reactor configuration are also developed to give full play to the performance of the whole catalysts system.
