Annotation. The main quantity of the produced ethyl alcohol is consumed by the food industry as a basis for the manufacture of alcoholic beverages, pharmaceuticals and other alcohol-containing products. In addition to food production, ethyl alcohol is widely used in medicine, perfumery, and other industries. The actual problem of alcohol production is finding ways to reduce the cost of raw materials and energy resources but still getting the world quality standard of alcohol. The best solution to the problem is to improve the technological schemes of rectification plants. For this, information was updated on modern schemes and methods for obtaining rectified alcohol. During the research, and information search was carried out in Russian and English language literary sources. A comparative analysis of books, manuals and articles on this topic was carried out, as well as the GOSTs requirements for rectification columns over the past few years were studied. The main components of rectification units were considered: contact devices (types of plate and packed devices) and rectification columns (applied pressure: atmospheric, vacuum, under a certain pressure; and their total number).Progressive schemes used in modern alcohol production in Russia and abroad (Ukraine, USA, France, Finland) were considered. Based on the received data, the following conclusions were formulated: the most effective types of contact devices are sieve and valve trays, among the packing there are Raschig rings, a promising type of columns is disc-type, the most popular scheme for the operation of a rectification plant is a combination of work under pressure and vacuum.
Key words: alcohol production, alcohol rectification, rectification plant scheme, rectification column, ethyl alcohol, rectified alcohol, contact apparatus.
