摘要
通过新建第二预切割塔,中国石油兰州石化公司乙烯装置产量达到设计值,解决了240 kt/a扩能改造后因实际裂解气组成偏重造成脱乙烷塔超负荷的问题,取得了较好的经济效益。
By adding a second predistillation column to the Ethylene Plant in Lanzhou Petrochemical Company, the designed ethylene output was achieved,thus solving the overload problem in the deethanizer and obtaining better economic benefits.
