INSTALLATION FOR REFINING OF OIL FEEDSTOCK Russian patent published in 1997 - IPC

FIELD: oil refining industry, production of light hydrocarbon fraction. SUBSTANCE: installation has rectifying column with lines to feed heated feedstock, to discharge liquid fraction and residue, heat exchangers with line to discharge condensate, condenser-dephlegmator, separator with line to discharge condensate, settling tank, gasoline collector and base. Installation is additionally equipped with horizontal four-row heat exchanger and settling tank has built-in heat exchanger and is connected by pipe-line to four-row heat exchanger. Rectifying column is installed on settling tank and has plates of cap type, condenser-dephlegmator is located in its upper part and is joined with pipe-line to centrifugal separator which is connected to small and large coolers located in sequence by means of steam line. Coolers are put vertically on gasoline collector. Installation allows light hydrocarbons with boiling finish of 120 C to be separated from condensate with simultaneous saving of energy by their heating and discharge with simultaneous rectification and condensation. Commercial automobile gasoline is produced on their bases and residual fraction including gasoline-naphtha-diesel fuel fraction which can be used as furnace fuel including domestic furnaces is also obtained. EFFECT: enhanced refining efficiency of installation. 1 dwg
