Abstract:
1. A liquid mixing collector for capturing and mixing liquid descending from an overlying zone in a mass transfer or heat exchange column, the collector comprising: at least first and second sumps; at least one opening positioned in each of said first and second sumps through which liquid can drain when present in said first and second sumps; at least first and second liquid collection regions at least partially bounded by said first and second sumps; at least first and second sets of spaced apart liquid collection channels positioned in each of said first and second liquid collection regions, said first set of liquid collection channels being interspersed with said second set of liquid collection channels in each of said first and second liquid collection regions; drain openings positioned in said liquid collection channels to allow liquid to drain from said liquid collection channels, when present therein, into said sumps, said first set of liquid collection channels in both of said first and second liquid collection regions being associated with said first sump so that liquid when present in said first set of liquid collection channels preferentially flows through the drain openings of the first set of liquid collection channels into said first sump, said second set of liquid collection channels in both of said first and second liquid collection regions being associated with said second sump so that liquid when present in said second set of liquid collection channels preferentially flows through the drain openings of the second set of liquid collection channels into said second sump; ascending vapor flow channels in a spacing between the liquid collection channels in each of said liquid collection regions; and a plurality of upwardly extending deflectors having surfaces for directing liquid when descending from said overlying zone into said liquid collection channels.
