摘要
In apparatus for fractionation of a superheated vapor from a riser cracking FCC reactor (4), the vapor is charged via transfer line (11) to the upper section (230) of a two-part fractionation column (130, 230). In the upper section (230), the superheated vapor contacts and vaporises a liquid fraction recycled from the lower section (130) of the column. The resultant vaporized liquid is discharged as a vapor fraction to the base of the lower section (130), where it is then fractionated to provide the required liquid hydrocarbon fractions. IMAGE
