摘要
大庆油田化工有限公司1,4-丁二醇装置副产的正丁醇溶液中主要杂质是甲醇、四氢呋喃、二甲醚和水,通过热力学分析和计算,可以采用精馏方式进行分离精制。通过PRO/II软件的模拟计算,正丁醇产品纯度可达99.99%,甲醇纯度可以达到98.965%。
The mainly impurities of the n-butanol solution produced by 1,4-butanediol production devise of Daqing Oil Field Chemical Industry Ltd. are methanol, tetrahydrofuran, methoxymethane and water, by the thermodynamic analyses and computations of the n-butanol solution,we can separate them by rectification .The whole recycling process is simulated by software,we can get n-butanol with the purity of 99.99% and methanol with the purity of 98.965%.
