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

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.
