Technological line and equipment for production of alcohol, bioethanol (Bragg rectification unit BRU)

The braggorectification process line is designed for the production of alcohol and bioethanol.
As an example, the description of the classical technological line of obtaining ethyl rectified food alcohol according to GOST R 51652-2000 on a seven-column indirect-acting braggorectification unit from starch-containing fermentation of raw materials is given.
The liquor from the fermentation compartment is fed to the liquor sections of the liquor heater, where it is heated by the heat of water-alcoholic vapours coming from the liquor column. Then, the broth goes to the CO2 separator, to separate carbon dioxide and alcohol vapours, which go to the condenser of the CO2 separator, are condensed and sent to the distillation column.
The heated liquor from the CO2 separator flows through the odour trap to the feed plate of the distillation column, which is heated by acute steam. Saturated water-alcoholic vapours from the upper plate of the distillery column are fed to the distillery heater, from where, having partially condensed, they are directed to the feed plate of the epuration ... .
