Process and system for preparation of hydrocarbon feedstocks for catalytic cracking

A process, apparatus and system for forming light olefins, the process including heating a resid-containing hydrocarbon feedstock containing at least 10 ppmw of metals to vaporize at least 90 wt. % of said hydrocarbon feedstock; separating in a knockout drum a hydrocarbon vapor portion having less t...

Zusammenfassung:A process, apparatus and system for forming light olefins, the process including heating a resid-containing hydrocarbon feedstock containing at least 10 ppmw of metals to vaporize at least 90 wt. % of said hydrocarbon feedstock; separating in a knockout drum a hydrocarbon vapor portion having less than 10 ppmw metals from a non-vaporized resid-containing portion; and feeding said hydrocarbon vapor to a catalytic cracking process to form light olefins.
