摘要
针对大连石化公司150kt/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20.54t/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。
An effective capacity expansion program was proposed and put into practice to solve the production bottleneck existed in the 150 kt/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.
