A method for separating a vapor from a carrier gas is disclosed. An air-sparged hydrocyclone is provided with a porous sparger covered by an outer gas plenum. A cryogenic liquid is provided to the tangential feed inlet at a velocity that induces a tangential flow and a cyclone vortex in the cyclone. The carrier gas is injected into the air-sparged hydrocyclone through the porous sparger. The vapor dissolves, condenses, desublimates, or a combination thereof, forming a vapor-depleted carrier gas and a vapor-enriched cryogenic liquid. The vapor-depleted gas is drawn through a vortex finder while the vapor-enriched cryogenic liquid is drawn through an apex nozzle outlet. In this manner, the vapor is removed from the carrier gas.
