1.2 Mt/a延迟焦化装置油气线结焦现象分析

摘要

After continuous operation of 2 years of the 1.2 Mt/a delayed coker in Urumchi Petrochemical Company,the coking in large oil & gas pipelines of coke tower was severe,which caused the coke tower pressure risen and influenced normal operation of the unit. By analyzing the coking phenomenon in the large oil&gas pipelines,combining the status quo of the coker and the problems existed in operation,the relevant optimization measures was put forward,good result was obtained.%乌鲁木齐石化公司1.2 Mt/a延迟焦化装置连续运行2 a后，由于焦炭塔大油气线结焦严重，导致焦炭塔压力升高，影响到装置正常生产。通过对该装置大油气线结焦现象分析，结合装置现状和运行过程中存在的问题，提出相应的优化措施，收到良好的效果。
