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

A gas separation method which separates vapor mixture consisting of at least two components to its component using a vapor-liquid contactor in a column;

• wherein said vapor-liquid is comprised of:
• a) a “non-promoting-fluid dispersion type” structured packing formed of various types of thin-sheets or tubes which direct the flow of said mixture vertically,
• b) said “non-promoting-liquid-dispersion type” structured packing having specific surface area of 350 m2/m3 or more,
• c) to contact said vapor and liquid countercurrently on the surface of said packing under a pressure of from 0.08 to 0.4 MPa, and at the vapor and liquid loads of 1.8 m/s (kg/m3)½ or more in superficial F factor.
