摘　　要：介绍了乙烯装置检修停车时,随着裂解炉逐台退出,裂解气压缩机逐渐引入其它装置提供的甲烷气和界区氮气,过渡至全氮气运行后通过调整维持长时间稳定运行,使装置系统内物料得以有效回收,减少损失,提高经济效益,实现了绿色环保停车。When the ethylene plant was shut down for overhaul,as the cracking furnaces were shut down one by one,methane from other units and nitrogen from battery limit were gradually introduced into cracking gas compressor.After transiting to full-nitrogen operation,long-period stable operation was maintained through adjustment,so as to effectively recover the materials in the system,reduce the loss and improve the economic benefit,thus achieving environmental friendly shutdown.
