Abstract: The present disclosure relates to processes, apparatuses, and systems for the removal of sulfur compounds from a heavy hydrocarbon feed as part of steam cracking processes to produce light olefins. In at least one embodiment, the process includes introducing a hydrocarbon feed having a first sulfur content to a steam cracker to produce a steam cracker effluent having a second sulfur content less than the first sulfur content. The process includes introducing the steam cracker effluent to a fractionation system to produce a light hydrocarbon product stream having a third sulfur content less than the second sulfur content.

Abstract: The invention generally relates to processes for separating steam cracker products by fractional distillation, and to systems and apparatus useful in such processes. More specifically, the invention relates to decreasing the amount of fractionator fouling that can result from increasing the amount of hydrocarbon molecules in the steam cracker feed having four or fewer carbon atoms.
