A MATHEMATICAL MODELING OF THE RISER REACTOR IN INDUSTRIAL FCC UNIT

摘要: In recent years, environmental regulations caused that the FCC units have found very important roles in oil refineries for improve quality of products. Thus, availability a modeling program is major importance unit optimization and scale-up or reducing problems unit. this article onedimensional adiabatic model riser reactor unit, was developed. The hydrodynamic described based on Patience et al. (1992) correlation .The chemical reactions were characterized by four- lump kinetic model, (Han Chung, 2001), (Juarez al., 1997) techniques applied to modify parameters. Comparison prediction data with industrial ones shows has been achieved adequately. Simulation studies are performed investigate effect changing process variables, such input catalyst temperature ratio (COR).
