Abstract:
This paper presents the simulation of the green petroleum coke calcining processes using the simulation program ASPEN HYSYS. The results are validated using actual industrial data. The present study provides a detailed description of the rate-based simulation. It considers the rate of physical and chemical phenomena of interest: the rate of moisture removal, the rate of volatile matter release and combustion, and the rate of coke dust and sulfur combustion. Data supplied by a local coke calcining kiln in operation are used to validate the simulation results. It is found that the rate-based simulation can be implemented as a useful tool to predict the operating conditions needed to control the content of undesirable impurities in the calcined petroleum coke, namely, sulfur, volatile matter and moisture contents. Except for the metal content, the simulation shows that it is possible for the kiln operator to process any type of green coke for varying sulfur, volatile matter and water c
ontents by adjusting the amount of tertiary air and/or fuel.
