本发明涉及一种侧线精馏与共沸精馏集成分离丙酮-醋酸-水的方法,步骤如下:将原料从侧线精馏塔T1的原料进料口送入塔内进行侧线出料精馏,塔顶富集液经冷凝后得到含量≥99.7%的丙酮,在侧线采出口处连续采出醋酸水溶液,塔底按时排放含固体颗粒杂质的溶液;再将醋酸水溶液从共沸
The invention relates to a method for integrated separation of acetone-acetic acid-water by side-line rectification and azeotropic rectification, which comprises the following steps: feeding raw materials into a tower from a raw material feed inlet of a lateral rectification tower T1 for side discharge rectification; After the top enrichment liquid is condensed, acetone with the content of more than or equal to 99.7% is obtained, the acetic acid aqueous solution is continuously taken out at the side outlet, the solution containing the solid particulate impurities is discharged on the bottom of the tower in time, and the acetic acid aqueous solution is further removed from the azeotropic
