METHOD OF OIL REFINING Russian patent published in 2012 - IPC C10G7/00 C10G7/02 

FIELD: oil and gas production.

SUBSTANCE: method includes heating and input of raw material into the column with steam supply from the top of the column after partial condensation to gas separation with obtaining gas and light petrol fraction and discharge of petrol and diesel fractions by side cuts of the column through the upper and lower steaming sections, and fuel oil from the bottom of the column, with the use of live and circulating reflux and input of heated streams into the column and steaming sections, gas supply from the top of gas separator to absorption with the use of preliminary cooled circulating reflux of the column as an absorbing agent, side cut from the bottom of the upper steaming section is steam stilled in reboiler and light petrol fraction from the bottom of gas separator is supplied to the top of the column and upper steaming section.

EFFECT: invention allows decreasing condensate quantity in dry gas, allows excluding the possibility of water phase formation on the trays of the column upper section, upper steaming section and in petrol fraction, thus improving the quality of obtained products - dry gas and stable gasoline that must be water free.
