PROCEDURE FOR PROCESSING OIL RESIDUES BY DELAYED COKING AND COKING REACTOR Russian patent published in 2011 - IPC C10B55/00 

FIELD: gas and oil production.

SUBSTANCE: coking reactor consists of cylinder case 1 with upper 2 and lower 3 bottoms and of support 12 set on foundation 13 made in form of horizontal circular plate positioned inside case 1. Fixture elements in form of vertical trapezoid gusset plates 15 connecting support 12 with case 1 are arranged on circular support 12. The coking reactor also includes branches for tangential inlet 8 of one part of raw stock and branches for radial inlet 9 of another part of raw stock. The branches for tangential inlet 8 of raw stock into a lower section of the reactor are set either in shell 19 with vertical walls, or in an upper section of lower throat 5 of height 1.5-2.0 metres. Branches for radial inlet of raw stock 9 are arranged radially in a lower part of conic bottom 3 at right angle to its surface and above level of branches for tangential inlet of raw stock 8. Branch of outlet of liquid phase 10 from a bottom of the reactor is positioned in a lower side part of neck 5 of the reactor.

EFFECT: reduced amount of bound together fractions preventing efficient coke unloading.
