    • PURPOSE: A refinement alcohol distillation system is provided to minimize facility size and to reduce installation investment cost. CONSTITUTION: A refinement alcohol distillation system comprises: a first extraction column(11) which extracts and distils crude liquor and isolates methanol-containing alcohol, fusel oil, fatty acid, and OH-free low boiling point compound; a refining column(31) for concentrating the alcohol; a product column(51) for separating the alcohol into methanol and ethanol; and a second extraction column(81) for separating the alcohol into alcohol steam and impurities. The system further comprises: an extraction column reboiler(43) for heating lower liquid of the first extraction column by thermal exchange of the lower liquid and overhead vapor of the refining column; and a product column reboilier(45) for heating the lower liquid of the product column.
    • 目的:提供精炼酒精蒸馏系统,以最大限度地减少设施规模,降低安装投资成本。 构成:精制酒精蒸馏系统包括:第一提取塔(11),其提取和蒸馏粗液并分离含甲醇的醇,杂醇油,脂肪酸和不含OH的低沸点化合物; 用于浓缩醇的精制塔(31); 用于将醇分离成甲醇和乙醇的产物柱(51) 和用于将醇分离成醇蒸汽和杂质的第二萃取塔(81)。 该系统还包括:萃取塔再沸器(43),用于通过精炼塔的下部液体和塔顶蒸气的热交换来加热第一萃取塔的下部液体; 和用于加热产物柱的下部液体的产物柱再沸器(45)。
