With the PRO II software, the absorption-stabilization process of a new FCC unit was simulated to optimize the energy conservation. The impact of changes of the compressor outlet flow path on absorption-stabilization process parameters and energy consumption was studied to propose measures for process optimization. The simulation results show that the duty of the stripper bottom reboiler and the compressed rich-gas cooler can be reduced greatly using two feeds with different composition and temperature to the stripper. The energy consumption can be reduced by 44. 04 MJ/t feed. Source
