Process for production of unsaturated hydrocarbons olefinicamente and integrated process for the production of unsaturated hydrocarbons and compounds aromaticos olefinicamente

摘要

Hydrocarbon feedstock containing petroleum residuum is catalytically cracked in a heavy oil cracking unit to produce a naphtha feed suitable for processing by steam pyrolysis to olefins. By the process integration disclosed, internal gas compression energy requirements for olefins recovery are furnished by steam generated in the heavy oil cracking unit.
