摘　　要：对某石化企业柴油加氢装置应用的有机朗肯循环(ORC)系统进行探讨,ORC系统利用该工艺的热资源,可产生1448kW的净发电功率,年净发电量为1249.9万kW·h,节约标煤4000t/a,对促进我国节能减排事业做出了贡献。该系统主要具有以下创新点:①开创了ORC系统在石化企业柴油加氢装置应用的先河,对于同等类似装置的节能减排起到了排头兵的作用;②自主研发的向心式涡轮膨胀机,具有效率高、易维护等优点,提高了中国ORC系统在石化企业的应用技术,为ORC系统更好的应用于实际生产项目做出了保障;③采用了蒸发式冷凝器,较管壳式冷凝器在换热性能上更有优势,有效降低了ORC机组的冷凝温度,提升了机组的发电功率;④ORC系统具有自动检测运行参数并进行调节的功能,实现了系统在变工况条件下的运行,实现了系统运行的稳定性。Organic Rankine Cycle(ORC) system used in diesel hydrogenation unit of a petrochemical enterprise is discussed in this paper,the ORC system can generate 1448 kW net power by utilizing the thermal resources of the process. The annual net power generation is 124.99 million kW·h,and the standard coal is saved by 4000 tons per year. It has contributed to the promotion of energy saving and emission reduction in China. The system has the following innovations:① It pioneered the application of ORC system in diesel hydrogenation unit of petrochemical enterprises,and played a leading role in energy saving and emission reduction of similar units. ② The centripetal turbine expander independently developed has the advantages of high efficiency and easy maintenance. It improves the application technology of ORC system in petrochemical enterprises and ensures the better application of ORC system in actual production projects. ③ The system uses evaporative condenser. The evaporative condenser is more advantages than shell-and-tube condenser in heat transfer performance,which effectively reduces the condensing temperature of ORC unit and improves the generating power of the unit. ④ The ORC system has the function of automatically detecting and adjusting operation parameters,realizing the operation of the system under variable operating conditions,and realizing the stability of the system operation.
