摘要：针对合成气一步法制备二甲醚的工艺路线,在进行了二甲醚吸收和精馏的实验基础上,提出了用水吸收一步反应冷凝后气相产物中的二甲醚的分离工艺流程:反应冷凝液相与吸收后的液体混合后进入二甲醚精馏塔,二甲醚产品从精馏塔侧线引出,塔底甲醇和水去甲醇精馏塔。在实验数据的基础上,对二甲醚分离工艺流程进行了模拟计算。
Based on the experiment of absorption and distillation of dimethyl ether （DME）, the separation process for high purity DME was proposed for the one-step synthesis of DME from syngas. The gas mixture of condensed one-step reaction resultants was absorbed by deionized water, and the mixture stream of liquid from absorber and liquid stream of condensed one-step reaction resultants was fed into the DME rectifyer. DME was drawn from the side stream of the DME rectifier. The bottom stream containing water and methanol was then fed into the methanol rectifyer. With the experimental data, simulation calculation of the separation process was made for reference.
