摘要: 应用PROII流程模拟软件,对某炼油厂新建催化裂化装置吸收稳定部分流程进行节能优化模拟。通过改变气压机出口部分流程,研究流程变化对工艺参数及能耗的影响,提出流程优化的具体措施。模拟结果表明,解吸塔采用不同组成、不同温度的双股进料可大大降低解吸塔塔底再沸器负荷与压缩富气冷凝负荷,装置能耗降低约44.04 MJ/t,节能效果显著。

Abstract: With the PROII 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.
