Abstract
Processes and systems for converting a wide boiling hydrocarbon mixture to chemicals herein heating a hydrocarbon feedstock to form a heated hydrocarbon feedstock. The heated hydrocarbon feedstock is separated to recover a vaporized light portion and a remaining liquid portion. The vaporized light portion is superheated and thermally cracked to recover a first cracked effluent, and the remaining liquid portion is heated and stripped to recover a stripped vapor mixture and a residue liquid portion. The stripped vapor mixture is separated to recover a vapor comprising the stripping medium and a stream comprising volatilized hydrocarbons. The volatilized hydrocarbons are heated and mixed with hydrogen then hydroprocessed to form crackable heavy hydrocarbons. The hydroprocessed effluent is separated to recover a hydroprocessed liquid stream comprising crackable heavy hydrocarbons and a hydroprocessed vapor stream comprising unreacted hydrogen. The hydroprocessed liquid stream is superheated and thermally cracked to recover a second cracked effluent.
