FIELD: petroleum product refining processes. SUBSTANCE: vacuum is created in fractionating tower by means of jet apparatus where part of flow of cooled lower circulating reflux is used as working medium; reflux is then cooled down, separated and return to vacuum column. Vapor-and-gas flow escaping from upper portion of fractionating tower is condensed and is separated into gas and liquid phases before jet apparatus. EFFECT: possibility of creation of high vacuum in fractionating tower; reduced loses of diesel fuel. 1 ex, 1 tbl, 1 dwg
