    Abstract: Vapor-liquid contacting apparatuses comprising both a primary absorption zone and a secondary absorption zone comprising a plurality of vortex contacting stages are described. The apparatuses provide improved heat and mass transfer between vapor and liquid phases in processes such as absorption, to selectively solubilize contaminants (e.g., acid gases) from an impure vapor (e.g., sour natural gas). Vortex contacting stage(s) in a zone of vapor-liquid contacting, such as a secondary or finishing absorption zone, are used following bulk absorption in a primary or main absorption zone.

    Abstract: Alkylation systems and processes are provided herein that include a slurry reactor. The slurry reactor receives a reactor feed slurry including catalyst and liquid isobutane, a olefin feed, and a circulating reactor vapor stream, where the slurry reactor produces a reactor liquid effluent stream, the reactor liquid effluent stream including catalyst, isobutane, and a liquid alkylate product. The catalyst in the reactor feed slurry can be regenerated catalyst from a catalyst regenerator. The catalyst can be regenerated after being removed from the liquid alkylate product and isobutane in the reactor liquid effluent stream.
