截至7月23日,中石化巴陵石化公司年产12万吨苯乙烯装置已成功运行一个月。目前装置各项控制指标正常,综合能耗可降低15%以上。至此,中国石化第二代节能型苯乙烯技术——顺序分离恒沸热回收技术工业应用取得成功。6月23日,该装置产出纯度为99.98%的合格苯乙烯,实现一次投料开车成功。一个月的运行结果表明,采用二代节能型苯乙烯技术的这套装置,乙苯-苯乙烯塔塔顶共沸换热器回收了塔顶70%左右的热量,每小时节省水蒸气约7吨,节能效果优于设计值,装置的综合能耗可降低15%以上,各项指标达到国际先进或领先水平。据悉,这套12万吨苯乙烯装置采用中石化上海石化研究院、华东理工大学、中石化上海工程公
As of July 23, Sinopec Baling Petrochemical Company with an annual output of 120,000 tons of styrene plant has been successfully run for a month. The current control device indicators normal, comprehensive energy consumption can be reduced by more than 15%. So far, Sinopec’s second-generation energy-saving styrene technology - sequential separation of azeotropic heat recovery technology for industrial success. June 23, the device output of 99.98% purity of qualified styrene, to achieve a successful car drove. The results of one month’s operation show that the second generation of energy-saving styrene technology, this device, ethylbenzene-styrene tower top azeotropic heat exchanger top of the tower to recover about 70% of the heat, saving about 7 per hour of water vapor Ton, the energy-saving effect is better than the design value, the comprehensive energy consumption of the device can be reduced by more than 15%, and the indexes have reached the international advanced or leading level. It is reported that this set of 120,000 tons of styrene plant Sinopec Shanghai Petrochemical Research Institute, East China University of Technology, Shanghai Petrochemical Engineering Corporation
