150kt/a苯抽提蒸馏装置扩能改造

针对大连石化公司150 kt/a苯抽提装置存在的生产瓶颈问题，提出了有效扩能整改方案。整改后标定结果表明，装置处理量达到了20.54 t/h，比原设计提高约15%，苯纯度达到99.9％以上，非芳烃中苯含量小于0.5％，操作平稳，助溶剂消耗明显降低。

CAPACITY EXPANSION OF A 0.15Mt/a AROMATICS EXTRACTION UNIT

An effective capacity expansion program was proposed and put into practice to solve the production bottleneck existed in the 0.15Mt/a aromatics extraction unit of Dalian Petrochemical Company. After revamping the unit throughput reached 20.54 t/h and it was 15% over the design target; the purity of benzene was more than 99.9%; the benzene content in raffinate oil was less than 0.5%; the operation was stable and the co-solvent consumption was reduced significantly.
