我国酒精提纯工艺进展

National Alcohol Rectifying Technology-A Review

工业酒精、食用酒精、无水酒精是酒精生产的三大方面,根据三者对酒精质量要求的不同,应采用不同的提纯方法。其中,食用酒精GB10343-2000新标准要求普级95.5%(v v)以上,因此,食用酒精提纯技术能较合适地反映酒精提纯技术水平。本文着重阐述了食用酒精的提纯技术等,并简要介绍了无水酒精提纯的传统技术和非传统技术。

A lcohol producing industry is constituted of industrial alcohol, eidble alcohol and absolute alcoho. Different rectifying techniques should be employed according to their respective qualitative requiremets. This paper mainly introduces the representative eiible alcohol purifying techniques including distillation technology, energy sparing methods, etc. Also, this paper simply dabbles in traditional and untraditional absolute alcohol rectifying techniques.
