Abstract
A gas/liquid interface structure for transport of a gas stream from an upstream source of same to a downstream processing unit, comprising first and second flow passage members defining an annular volume therebetween, with the second flow passage member extending downwardly to a lower elevation than the lower end of the first flow passage member, with an outer wall member enclosingly circumscribing the second flow passage member and defining therewith an enclosed interior annular volume, and with a liquid flow port in the outer wall member for introducing liquid into the enclosed interior annular volume. The second flow passage member includes an upper liquid-permeable portion in liquid flow communication with the enclosed interior annular volume, whereby liquid from such volume can "weep" through the permeable portion and form a falling liquid film on interior surface portions of the second flow passage member, as a protective liquid interface for the second flow passage member.
