INVESTIGATION OF EFFECTIVE PARAMETERS ON FCC RISER USING COMPUTATIONAL FLUID DYNAMICS ANALYSIS

Fluid catalytic cracking (FCC) is a major conversion process in modern petroleum refineries worldwide. This study presents computational fluid dynamics (CFD) modelling of the kinetic reaction in FCC gasoline riser. This study reveal that, a high reaction temperature and a long reaction time are beneficial to producing clean low-olefin gasoline and more propylene. A low catalystto- oil ratio might be better for the current FCC gasoline riser.
