| 摘 要： | 分析了乙烯装置大检修造成的损失,主要包括物料损失,开、停车过程的能耗,检修费用和减产损失。大检修使中型乙烯装置的直接经济效益减少约0.82亿元,大型乙烯装置的直接经济效益减少约1.57亿元,其中减产造成的直接经济效益损失所占比例最大(大于60%)。将中国石油化工集团(简称中国石化)乙烯装置的运行周期与国外乙烯装置的运行周期进行了对比,分析了影响中国石化乙烯装置长周期运行的因素,提出通过采用设备风险评估技术强化设备管理、引入新型助剂脱除限制乙烯装置长周期运行的瓶颈、采用在线处理消除长周期运行的安全隐患、优化工程设计和更新检修理念延长乙烯装置运行周期等对策。

| Abstract: | Problems and solution for long-period running of ethylene installation were discussed.Loss caused by maintenance of ethylene plant including material loss,energy consume of shutting down and starting up of installation,maintenance cost and reduction of output made up more than 60% of total loss.During maintenance,a medium-scale ethylene installation lost direct economic profit about 82 million yuan,as well as a large-scale ethylene installation lost direct economic profit about 157 million yuan.In comparing turnaround interval of SINOPEC's ethylene installation with internationals,factors affecting turnaround interval of ethylene installation were analyzed.By using equipment venture evaluation,new promoters,on-line handling,optimizing engineering design and regenerating maintenance idea,turnaround interval of ethylene installation could be prolonged and economic profit could be maximized. |
