ABSTRACT:
A liquid-vapor contact apparatus has pairs of vertical outer walls disposed in the manner of the vertical faces of a cuboid. The apparatus includes a plurality of spaced, parallel, vertical plates. Between each pair of adjacent plates there is a packing comprising a vertical array of corrugated liquid-vapor contact elements of the type that are used in structured packing. The corrugations in each element slope from top to bottom in a direction opposed to that in which the corrugations in contiguous elements slope. The two outermost plates form the walls of the apparatus. The walls comprise alternate edge portions of plates and of spacer bars. The plates define first and second sets of passages, respectively. One set of passages performs a first fractionation duty, and the other set another fractionation duty.
