A non-adiabatic vapor-liquid contact device is disclosed which achieves high heat transfer effectiveness without sacrificing mass transfer effectiveness. Referring to the figure, a helical coil of crested tubing (84) is contained within the annular space between shrouds (82 and 83). Liquid flows downward through the annulus, and vapor flows countercurrently upward. The mass exchanging fluids pass through the space between tube crests and the shroud achieving very effective mixing. Heat transfer fluid is flowed through the tubing via connections (87 and 88). The heat and mass transfer is preferably additionally enhanced by interspersing contact media with the coiled tubing, longitudinally and radially.
