摘要
对于丙酮合成MIBK一步法工艺中轻组分回收需求,提出了分子筛膜分离与精馏相结合的工艺,并建成国内首套2 300 t/a轻组分物料的分离提纯工业装置,产出符合要求的丙酮、异丙醇产品,与可循环利用的MIBK粗品。该装置的异丙醇综合收率93.1%,丙酮综合收率87.4%,MIBK粗品收率接近100%。经运行能耗测算与经济性分析,该装置投入后5 a共可产生6 362.1万元的经济效益,共增加1 328.2万元利润。
In the light of the demand to recover light components from the one-step acetone to methyl isobutyl ketone(MIBK)synthesis process,a distillation-zeolite membrane coupling process is proposed,and China’s first 2300 t/a industrial plant using this process is built and starts up,which produces qualified acetone and isopropanol,as well as crude recyclable MIBK.Comprehensive recover rates of acetone and isopropanol products from this plant are 87.4%and 93.1%,respectively,and the recovery rate of crude MIBK approaches 100%.Through calculating energy consumption and conducting economic analysis during operation,it is indicated that this industrial plant can receive RMB 63.621 million of income and RMB 13.282 million of profit in 5 years.
