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

FIELD: oil refining.

SUBSTANCE: method involves heating and input of raw materials into a column with release of vapours from the top of the column after partial condensation on gas separation with obtaining of a gas and a light petrol fraction and separation of petrol and diesel fractions by off stream through steaming sections. Oil residue is released from the bottom of the column. Live and circulating refluxes are used and heated streams are fed into column and steaming sections. The whole light petrol fraction from the bottom of the gas separator is fed to the top of the column as live reflux, and the gas undergoes absorption with use of an absorbent in the form of a pre-cooled circulating reflux of the column.

EFFECT: improved method of refining oil.
