Abstract: Processes and systems for the integrated production of propylene and an alkylate, such as cumene, may include feeding a hydrocarbon feedstock containing propane to a propane dehydrogenation reaction zone to convert a portion of the propane to propylene. The propylene is separated in a separation system to form a polymer-grade propylene stream, a low purity propylene stream, and a propane stream. The low purity propylene stream is then fed to an alkylation reaction zone where the propylene is reacted to produce an alkylated product and generate a low pressure steam. The low pressure steam may then be fed to the separation system as a heat source, integrating the dehydrogenation system and the alkylation system.

Abstract: Processes and systems for recovery of a dilute ethylene stream are illustrated and described. More specifically, embodiments disclosed herein relate to processes and systems for separation of a dilute ethylene stream from an offgas or other vapor streams, where the ultra-low temperature refrigeration for the desired separations is provided by the offgas itself, and only moderately-low temperature externally supplied propylene refrigerants (for example, at −40° C. to 15° C.) are necessary.
