乙烯装置能耗指标分析与优化措施

ANALYSIS ON ENERGY CONSUMPTION INDEX OF ETHYLENE PLANT AND THE OPTIMIZATION MEASURES

中国石油四川石化800 kt/a乙烯装置投产以来能耗指标一直偏离设计值。介绍了乙烯装置主要的能耗指标。与同类乙烯生产单位的指标对比,发现了该装置在能耗方面存在的问题和不足。通过逐一对装置能耗指标进行分析,找出超标原因,进而提出优化措施,并且结合本单位实际生产情况提出完善方案。从而保证了乙烯装置稳定高效运行,达到了增加乙烯产能、降低能耗、提高总体经济效益的目的。

Since the 800 kt/a ethylene plant at PetroChina Sichuan Petrochemical Company Limited was put into operation,its energy consumption index has deviated from the design value.The main energy consumption indexes of ethylene plant are introduced in this paper.By comparing with the indexes of similar ethylene production units,the problems and shortcomings in terms of energy consumption during ethylene production were found.Through the analysis of energy consumption indexes of the plant one by one,some optimization measures were put forward and some improvement schemes were put forward according to the actual production,thus ensuring the stable and efficient operation of ethylene plant and achieving the purposes of increasing ethylene production capacity,reducing energy consumption and improving overall economic benefit.
