Abstract copyright Andrew W. Sloley

Fluid Catalytic Cracking Units (FCCU) recover low-level energy by integrating the FCCU main fractionator with the FCCU gas concentration plant. The gas concentration unit deethanizer reboilers are a major energy recovery site. Careful process simulation of the entire unit to determine the available heat levels is critical for proper unit design. Proper simulation models will allow for rapid evaluation and design of capable process control schemes. An example of an actual 7,940 M3/D (50,000 BPD) capacity operating unit is presented to show the methodology and benefits of simulation-modeling-based analysis of unit configu-rations and control schemes. A base scheme is shown. Improvements in an alternate scheme are developed and presented.
