摘　　要：针对现有“双塔流程”的缺点 ,应用流程模拟和总体优化技术 ,提出了一个新的节能的吸收稳定系统工艺流程。该流程采用油吸收脱乙烷塔代替原有的吸收塔和解吸塔 ,并对换热网络重新进行了匹配 ,从而取消了原“双塔流程”的两股返回物料 ,新流程不但增加了产品的回收率 ,而且还降低了能耗。新流程与“双塔流程”相比 ,按催化裂化装置 1.2Mt/a处理量计 ,在同样的进料和产品规格下 ,年净增经济效益达 11.44× 10 6 RMBTo surmount deficiencies of the existing 'double columns',a novel energy saving process for absorption and stabilization systems of FCCU was put forward by using process simulation and global optimization.Using an oil absorption deethanizer to replace both absorber and desorption tower,and rematching the heat exchange network,two recycle streams,the absorber bottoms and the stripper overhead,were eliminated.Compared to the 'double column' process,the product recovery rate enhanced and energy consumption decreased.For a FCCU with processing capacity 120 000 0 t/yr,the revenue reached 11.44×10 6 RMB$.
