对比山东华星集团与海南实华嘉盛化工有限公司稀乙烯制乙苯装置,就传热介质方面,讨论两者装置能耗、安全性能及稳定性,同时分析运行中所存在的问题,并作出处理建议。结果表明用导热油替代水蒸汽作为传热介质,单位综合能耗降低45.37kgEoil/tEB,且安全性与稳定性较好。针对导热油的节能及经济优势,对实华嘉盛乙苯装置传热系统提出了初步的动改建议。
Compare the energy consumption, safety performance and stability of the equipment between Shandong Huaxing Group and Hainan Shihua Jiasheng Chemical Co., Ltd. on the dilute ethylene ethylbenzene plant, and discuss the energy consumption, safety performance and stability of the two plants in terms of heat transfer medium, and analyze the problems existing in the operation and make Processing advice. The results show that the use of HTF instead of water vapor as a heat transfer medium, unit energy consumption decreased by 45.37kgEoil / tEB, and the safety and stability is better. In view of the energy saving and economic advantages of the HTF, a preliminary proposal for the change of the heat transfer system of Shihua Jiasheng ethylbenzene plant was put forward.
