摘　　要：东方石化苯乙烯装置脱氢单元受后冷却系统能力的限制和高温天气公用工程循环水系统温度高的影响,苯乙烯装置脱氢单元负荷最高只能维持在90%左右生产,尾气压缩机C3001进出口温度偏高,苯乙烯夹带量偏多导致出口集液包及换热器频繁堵塞,3.2 MPaG蒸汽用量偏高等问题。通过分析总结,制定系统优化及改造方案。This paper introduces the DFSH styrene unit dehydrogenation unit by the dehydrogenation unit post-cooling system capacity and high temperature utility circulating water system temperature,The maximum load of styrene unit dehydrogenation unit can only maintain about 90%production,and the inlet and outlet temperature of tail gas compressor C3001 is high,The excessive amount of styrene entrainment led to the frequent blockage of the outlet liquid collecting package and heat exchanger,and the high amount of 3.2 MPaG steam was analyzed and summarized,and the system optimization and transformation scheme was formulated.
