| 摘 要： | 针对甲醇废气造成的大气污染和资源浪费问题,采用1-丁基-3-甲基咪唑四氟硼酸盐([bmim][BF4])为目标离子液体与水的混合溶剂,捕捉回收再利用废气中的甲醇。利用Aspen Plus对吸收进行工艺模拟与优化,最终确定[bmim][BF4]温度为30℃,流量比为3:1,吸收剂用量为380 kg/h。甲醇回收率达到99.7%。与水作吸收剂的传统工艺相比,解吸塔冷凝器节省循环水31.3%,再沸器节省加热蒸汽50.6%。

| Abstract: | In view of the air pollution and resource waste caused by the methanol in the emission of industrial waste gas, ionic liquid [bmim]]BF4] mixed with water was used to capture and recycle the methanol. Aspen Plus software was used to simulate and optimize the process of absorption, the best process conditions were determined as follows: the temperature 30℃,the flow ratio 3:1 and absorbent dosage 380 kg/h. Compared with traditional method of using water as absorbent, circulating water was saved by 31.3% in the analytical tower condenser, and heating steam was saved by 50.6% in the reboiler. |
