Abstract
Abstract In order to provide improved gas-liquid contacting, such as isothermal absorption conditions, there is provided a continuous vertically elongated heat exchange conduit positioned to extend centrally through substantially the entire height of the contacting vessel. Thus, a suitable cooling stream flowing through the conduit can, for example, provide for removing the heat being released as certain components from a gaseous stream condense into a countercurrently flowing liquid absorption phase. A preferred vessel design positions the heat exchange conduit axially through the chamber and also has fins on the conduit wall to enhance its heat exchange efficiency in contacting the liquid phase.
