摘要
小乙烯经一轮改造经济效益虽有所改善,但尚不能摆脱困境。文中统计了过去和现在乙烯工程建设中的相关数据,并经过分析比较,提出了二轮改造的方案,即改造后的规模大于或等于500kt/a乙烯才能摆脱困境,并采取建1条平行线的改造方式为宜。
Although the economic benefit of some small scale ethylene plants has been improved to some extent after the first run revamping, they still cannot get out of economic problems. Based on the analysis and comparison of the previous and current relative statistics data about some ethylene projects, proposal for the second run revamping is put forward. As a result, a scale of not less than 500kt/a is appropriate for the revamping of ethylene plants and a new parallel line is suggested to add.
