Abstract
Vapor-liquid contacting apparatuses and methods for removing contaminants from gas streams are provided. In an embodiment, a vapor-liquid contacting apparatus includes a vortex contacting stage having a contacting zone bound by a wall and defining an axis, a radially inner region surrounding the axis, and a radially outer region adjacent the wall. The vapor-liquid contacting apparatus also includes a feed conduit configured to direct flow of a feed gas into the radially outer region of the contacting zone in a direction tangential to the axis to form a vortex. Further, the vapor-liquid contacting apparatus includes a liquid conduit configured to deliver a liquid absorbent stream to the radially inner region in the contacting zone.
