Vapour-liquid contactor, cryogenic air separation unit and method of gas separation

摘要

In an vapor.liquid contactor 4a for flowing down a liquid along the surface of a packing and contacting said liquid with the vapor while ascending the vapor, the improvement being characterized in that said packing is a non-promoting fluid-dispersion type structured packing A1, A2 in which various types of thin sheets or tubes for determining the flow direction of the above liquid or vapor is laminated and arranged in the perpendicular direction, and said contactor includes at least one fluid distribution unit E1, E2 formed of a rough distribution part C1, C2 to distribute the liquid roughly and a minute distribution part B1, B2 to distribute the liquid minutely and equally.
