METHOD OF OIL REFINING Russian patent published in 2008 - IPC C10G7/02 

FIELD: chemistry.

SUBSTANCE: method includes raw materials injection to the first rectification column and residuum of the first column to the second rectification column with steam feeding from the upper part of the column to gas separation with emission of gas and light-weight gasoline cut, which are delivered for refluxing, tapping of gasoline and diesel oil cuts through the steaming sections and tapping of oil residue from the bottom half of the second column, after separation gases are exposed to absorption with getting of dry and wet gases, notably that to get such gases before cooled top and bottom of the circulating reflux of the second column are used as an absorbent and after adsorption they are returned, at the same time after gas separation light-weight gasoline cuts are delivered to the second column refluxing.

EFFECT: quality improvement of separation products and decrease of energy consumption.
