丙酮是优良的有机溶剂和重要的化工原料之一,其质量直接影响到下游化工产品的品质。甲醇是丙酮产品中的杂质之一,影响其质量。本文分析了工业生产中甲醇的来源,并根据生产实际情况,提出两种降低甲醇的方法。第一,在现有生产工艺的条件下,改变操作方法;第二,增加一脱甲醇塔,从而提高丙酮产品质量。 Acetone is an excellent organic solvent and one of the important chemical raw materials, the quality of which directly affects the quality of downstream chemical products. Methanol is one of the impurities in acetone products, affecting its quality. This paper analyzes the source of methanol in industrial production and proposes two ways to reduce methanol according to the actual production. First, change the method of operation under the conditions of existing production processes. Second, add a methanol-removal tower to improve the quality of acetone products.
