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: Processes for upgrading a hydrocarbon for a predetermined period of time. The process can include determining an amount of one or more contaminant-containing compositions that will be present in a pyrolysis effluent based, at least in part, on a composition of a hydrocarbon feed to be steam cracked, a. temperature the hydrocarbon feed will be heated at during steam cracking, a residence time the hydrocarbon feed will be heated at the temperature during steam cracking, or a combination thereof. In some examples, the process can also include taking one or more steps to allow the hydrocarbon feed to be steam cracked for at least as long as a predetermined, period of time, such as controlling process conditions within one or more separation stages to favor certain product compositions and/or introducing a predetermined amount of one or more materials into various locations of the process, or any combination thereof.

Abstract: The present disclosure relates to hydrocarbon pyrolysis of advantaged feeds. The advantaged feeds can comprise hydrocarbon, at least one halogen-containing composition, and at least one metal-containing composition, where the halogen-containing composition and the metal-containing composition are substantially different compositions. The disclosure encompasses steam cracking of advanced feeds comprising hydrocarbon and one or more of chloride-containing compositions, nickel-containing compositions, and vanadium-containing compositions.

Abstract: Processes are provided for removing contaminants from a refinery gas. Such process can include recovering a process gas comprising ethylene and propylene from a steam cracker effluent recovered from a stream cracker in a steam cracker facility. A refinery gas can be recovered from a refinery facility. The process gas can be compressed in a plurality of compressor stages. A pressure of the refinery gas can be determined. A compressor stage in the plurality of compressor stages can be selected for introducing the refinery gas using the determined pressure of the refinery gas. The refinery gas can be introduced into the selected compressor stage to produce a combined gas that can include the process gas and the refinery gas. At least a portion of one or more impurities can be removed from the combined gas in the steam cracker facility to produce an upgraded combined gas.
