A fluidized bed catalytic cracking regenerator model

Abstract

AbstractA grid model including thermal effects is proposed. The aim is the simulation of a fluidized catalytic cracking regenerator similar to the industrial unit of Destileria La Plata, YPF, Argentina.It is demonstrated that a simple C.S.T.R. model without bypass of gas feed entering the bed provides a good approach for representing the fluidized bed including the grid region.In addition, by means of the C.S.T.R. model, it is shown that there exist two characteristic operating regions: a zone where (Coo – Co) depends on the initial coke concentration and a zone where (Coo – Cc) is controlled by oxygen supply.
