Abstract: Devices, methods, and systems for stripping a vapor from a gas are disclosed. A carrier gas is bubbled through a liquid coolant in a vessel. The vessel contains a mesh screen, packing materials, or combinations thereof. The carrier gas has a vapor component. The vapor component condenses, freezes, deposits, desublimates, or a combination thereof out of the carrier gas onto the mesh screen, the packing material, or combinations thereof, as a solid component. The solid component dissolves into the coolant as the coolant passes through the mesh screen, the packing material, or combinations thereof.

Abstract: A device and a method for separating a vapor component from a gas is disclosed. A vessel comprising a top portion and a bottom portion is provided. The top portion comprises a gas outlet, a fluid inlet, and a direct-contact heat exchanger. The bottom portion comprises an indirect-contact heat exchanger, a gas inlet manifold, and a fluid outlet manifold. The indirect-contact heat exchanger is aligned vertically and comprises parallel exchange surfaces. Plenums between the exchange surfaces comprise alternating, adjacent ascending gas channels and descending fluid channels. The gas inlet manifold comprises one or more inlets adjacent to a top portion of each of the ascending gas channels. The fluid outlet manifold comprises one or more outlets adjacent to a bottom portion of each of the descending fluid channels.
