METHOD OF FRACTIONAL DISTILLATION OF HYDROCARBON MATERIAL

摘要

FIELD: chemistry. ^ SUBSTANCE: method is fractional distillation of hydrocarbon material in rectification column which has upper circulating reflux. Distillate product from the upper part of the column is cooled down, condensated and separated in the reflux tank, from where hydrocarbon gas separated from rectificate is drawn off with the liquid gas jet device, actuating medium of which is cooled upper circulating reflux from the column. The blend of upper circulating reflux and hydrocarbon gas is delivered from the jet device for separation at pressure which is higher of pressure in the reflux tank. As a result of separation topped hydrocarbon gas is separated from the upper circulating reflux which is returned to the rectification column. ^ EFFECT: decrease of hydrocarbon content in fuel hydrocarbon gas and enhancement of intensity of hydrocarbon material processing. ^ 1 ex, 1 tbl, 1 dwg
