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.
