FCC-SIM™

FCC unit operation is a key economic driver in many refineries. Do you need to evaluate feed alternatives for your unit? Are you air blower or regenerator constrained? Do you need to decide whether to push feed rate or conversion? FCC-SIM can help determine the answers to these important questions. It is based on a first-principles engineering framework and is an accurate, easy-to-use tool with over twenty years of application in refineries worldwide.

FCC-SIM is a valuable tool that can be used to analyse your FCC and predict results for a wide range of feedstocks and operating conditions. You can use FCC-SIM to answer “what if” questions, develop LP model coefficients, make catalyst decisions, monitor key processing parameters, and train personnel.

FCC-SIM is licensed for use on over 180 commercial FCC units by leading refining, catalyst, and engineering companies, making it the industry’s tool of choice.
