摘　　要：针对仪征化纤聚酯11单元102℃常压余热蒸汽提出了采用有机朗肯循环(ORC)系统的发电工艺。利用Aspen Plus 7.3流程模拟软件,分析了ORC系统的蒸发压力、冷凝压力、过热度和过冷度对系统热效率和效率的影响。当蒸发压力为1.28 MPa,冷凝压力为0.16 MPa,过冷度和过热度都为0时,系统效率最高。该操作状态下,静态回收期为3.5~5.6年。The Organic Rankine Cycle （ORC） power generation process was proposed for the 102 ℃ waste heat recovery of Yizheng chemical fibre polyester unit 11. The effects of evaporation pressure, condensation pres-sure ,degree of superheated and subcooling on the energy efficiency and exergy efficiency of the process were inves-tigated for the proposed process based on Aspen Plus V7. 3. When the evaporation pressure was at 1.28 MPa, con-densing pressure at 0. 16 MPa, degree of subcooling and superheat at 0, system efficiency was the highest. The process of the static payback period was 3.5 -5.6 years.
