METHOD FOR RETARDED COKING OF OIL RESIDUES AND COKING REACTOR Russian patent published in 2008 - IPC C10B55/00 

FIELD: oil and gas industry.

SUBSTANCE: method includes heating of source raw material, mixing it with a re-circulator - heavy gas-oil of coking in a cube part of a rectification column, heating of produced secondary raw material to coking temperature and coking in a reactor with withdrawal of steam-gas products of coking, their cooling and separation in a cyclone with extraction of steam and liquid phases; at that, the steam phase if withdrawn into the concentration part of the rectification column for separation, while a liquid part is withdrawn directly from the cyclone into the reactor. The reactor for implementation of the suggested method includes a cylinder case with sleeves of secondary raw material input and withdrawal of steam-gas products of coking, at the upper portion of the cylinder the cyclone is installed, the inter-circular space of which is connected with the steam-gas withdrawal sleeve, while the lower part of the cyclone is connected with the reactor cavity; at that the cyclone is equipped with a sleeve for input of a cooling jet.

EFFECT: simplification of coke production process and increases service life of secondary raw material heating furnace.
