本发明涉及醋酸间接加氢法单产或联产乙醇和醋酸乙酯的工艺,首先将醋酸与乙醇置于酯化塔中,在酸催化剂的作用下进行反应精馏,得到醋酸乙酯和水,上述混合物经塔顶镏出,冷凝后进分水器、精馏脱轻塔以及精馏脱重塔,以脱除杂质,最后得到合格的醋酸乙酯产物,该产物部分作为产品出售,部分作为氢解反应生产乙醇的原料导入氢解塔中进行催 The invention relates to a process for the indirect or indirect hydrogenation of acetic acid with ethanol and ethyl acetate. The method comprises the following steps: placing acetic acid and ethanol in an esterification tower, performing reactive distillation under the action of an acid catalyst to obtain ethyl acetate and water, The above mixture was purged from the top of the column, condensed into a water separator, rectified light tower and distillation tower to remove impurities, The solution of ethanol production of raw materials into the hydrogenysis tower for reminders
