Abstract: A method for scrubbing flue gas, comprising: providing a rotating packed bed device onboard a ship or an offshore floating vessel; mixing seawater with the flue gas under centrifugal force in the rotating packed bed device to prevent blow-by and produce a scrubbed flue gas having low sulfur; and discharging the scrubbed flue gas; wherein the scrubbed flue gas has less than half of the sulfur that was originally present in the flue gas before the mixing. Also, a system for scrubbing the flue gas according to the method described. Also, a marine ship, comprising: an engine that combusts HSFO; a rotating packed bed device, in a hull or funnel of the ship, comprising a rotating shaft and a porous material that mixes seawater with flue gas and reduces sulfur in the flue gas; and a connector from the engine and the rotating packed bed device.

Abstract: We provide a process for regenerating a spent acidic ionic liquid, comprising contacting the spent acidic ionic liquid with hydrogen and without an addition of a hydrogenation catalyst; wherein a conjunct polymer content is decreased in the spent acidic ionic liquid to produce regenerated acidic ionic liquid. We also provide a process for making an alkylate gasoline blending component, comprising: a) alkylating a mixture of isoparaffins and olefins using an acidic ionic liquid and an alkyl halide or a hydrogen halide, wherein a conjunct polymer accumulates in a spent acidic ionic liquid; and b) feeding the spent acidic ionic liquid and a hydrogen, and without an addition of a hydrogenation catalyst, to a regeneration reactor operated under selected hydrogenation conditions to produce a regenerated acidic ionic liquid that is used for the alkylating, wherein the conjunct polymer in the regenerated acidic ionic liquid is decreased by at least 50 wt %.
