Many fluid catalytic cracking (FCC) units operate at a slide-valve differential pressure limitation. The limitation, in many instances, can be eliminated, thus allowing an increase in the catalyst circulation rate. Additional catalyst circulation rate often directionally improves product selectivity by maximizing the number of active sites the oil encounters while passing through the riser. This improvement, in turn, increases unit profitability. Slide-valve differential pressure can be optimized using a logical, three-step approach. This procedure involves optimizing: the aeration rates in the standpipe; the pressure balance between the reactor and regenerator vessels; and the physical properties of the catalyst. The paper describes these procedures.
