Title: Inverted fractionation apparatus and use in a heavy oil catalytic cracking process

Abstract

This patent describes a process for fractionating a superheated, cracked vapor stream having a temperature above about 750{degrees} F. and comprising a full boiling range cracked product stream including normally gaseous hydrocarbons, at least normally liquid product streams selected from the group of naphtha boiling range hydrocarbons, light cycle oil boiling range hydrocarbons, heavy cycle oil boiling range hydrocarbons and mixtures thereof into liquid product fractions, the process comprising charging the superheated vapor to a vertical distillation apparatus having a height of at least 20 meters, and comprising an upper desuperheating zone and a lower fraction zone.
