| 摘要 |
The invention concerns a plant for the target withdrawal of upper intermediary admixtures from the rectification cycle, which plant contains alcohol column being connected by vapor communication with fractionating column and condenser, and also through the fusel alcohol condenser û to the admixtures concentration column which contains fractionating column and condenser it is connected to the collector of special water, to the fusel oil extractionunit, at that the zone of selection of upper intermediary admixtures û fusel alcohol of 17-23 discs of alcohol column, and connected by vapor communication through the vapor separator with the upper part of tube space of fusel oil condenser, and lower part of the tube space of condenser through flow-measuring apparatus - to 15-20 discs of the admixtures concentration column which still part of which is connected to the lower part of alcohol column for outlet of aqueous-alcoholic liquid, the tubespace of the column of admixtures concentration isconnected by communication of upper intermediary admixtures with main fraction lantern through the flow-measuring apparatus, collector of special water is connected through the flow-measuring apparatus to 3-5 discs counting from above, column of admixtures concentration, and lower part of fusel oil extraction unit is connected through the vapor and injection pump to 10-15 discs above the column ofadmixtures concentration.
