ABSTRACT:
A fractionation method and apparatus is disclosed for separating and recovering condensed and absorbed coke vapor from residual material leaving a coker combination tower to thereby obtain increased distillate yield. A resid flash down tower is positioned between the coker combination tower and a delayed coke furnace and operated to recover the higher value liquid product from the residual material containing absorbed coke vapor.
