Abstract

The invention provides an anhydrous ethanol production process, which includes the following steps: S1 raw material crushing: crushing the raw material into fine powder, adding amylase and water to mix into a uniform mash; S2 liquefaction treatment: heating the uniform mash and transporting Enter the liquefaction process in the liquefaction tank and transform into liquefied mash; S3 fermentation: cool the liquefied mash and send it to the fermenter, add additives and ferment to obtain a fermented mature mash with a wine content of more than 16%; S4 distillation: ferment the fermented mash The mature mash is sent to the distillation tower for purification and dehydration. Through the cooperation of various processes, anhydrous ethanol with a wine content of more than 99.5% can be prepared. At the same time, through the optimization of each process process, the alcohol conversion rate of grain raw materials is effectively improved. In the distillation process, through the cooperation of the reboiler and heat exchanger, the alcohol vapor at the top of the rectification tower is used to heat the combined tower, and the alcohol vapor at the top of the combined tower is used to heat the beer tower, which reduces the energy consumption in the manufacturing process.

Description

technical field [0001] The invention relates to the field of fuel ethanol production, in particular to an anhydrous ethanol production process. Background technique [0002] With energy saving and emission reduction becoming the mainstream environmental protection slogan in today's world, ethanol gasoline is gradually being used to replace traditional gasoline. Ethanol gasoline refers to the special gasoline component oil (produced by refineries or petrochemical plants) In the blended oil produced for blending ethanol gasoline for vehicles), a certain proportion of denatured fuel ethanol is added according to the volume ratio, and the fixed-point blending center of ethanol gasoline for vehicles is mixed through a specific process according to the quality requirements of the national standard GB18351-2004 A new generation of clean and environmentally friendly vehicle fuel. The adjustment of energy structure and the reduction of environmental pollution have promoted the devel...
