ABSTRACT:
A non-adiabatic vapor-liquid contact device is disclosed which achieves high heat transfer effectiveness without sacrificing mass transfer effictiveness. Referring to FIG. 2, a helical coil of crested tubing 84 is contained within the annualr 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.
