Abstract
Kinetic analysis of the green petroleum coke calcining processes using the simulation program HYSYS and actual industrial data is presented. The rates of physical and chemical phenomena of interest, such as the rate of moisture removal, rates of volatile matter release and combustion, rates of coke dust and sulphur combustion were all represented by their kinetic models. This paper gives a detailed description of the simulation of these processes using HYSYS "kinetic reactor" module. The results were compared with actual industrial rotary kiln data in order to validate the simulation and there was a reasonable agreement for the two different GPCs considered. The methodology of kinetics-based simulation described in this study may be used to predict coke calcining kilns performance regardless of the green coke composition.
