ABSTRACT

There is an ever increasing demand for high quality yields and products from chemical processes. Chemical processes are very complex to undusted design and operate.  In the petroleum refinery systems, the regenerators of the fluid catalytic cracking unit play key roles.  The reactor-regenerator system is the main facility. The activation of the spent catalyst takes place in the regenerator.  A model of the regenerator that adepts two phase theory of the regeneration of the spent catalyst has been presented using Aspen Hysys version 8.4.  The model is based on its temperature, and pressure conditions and flow rate of the air.  The profiles of the quality of the burnt coke, air flow rate, flue gas compositions are presented.  These parasites were compared with practical data from a Nigerian refinery.
