Abstract
Abstract The liquid distributor is provided with a main channel, a plurality of secondary channels for receiving liquid from the main channel and a plurality of flow channels which extend laterally from each secondary channel in order to discharge liquid in the form of liquid streams. The flow channel permits a uniform distribution of the liquid across the cross-section of a mass transfer/heat exchange section of a mass transfer/heat exchange column. The flow channels may be in the form of downwardly bent tubes, downwardly angled tubes or troughs with downwardly directed tubes at one end or orifices at one end.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
100 words
A liquid distributor for an exchange column comprising an open main channel for receiving a flow of liquid; a plurality of secondary open channels disposed at spaced apart intervals and in communication with said main channel to individually receive a flow of liquid therefrom; and a plurality of flow channels connected to at least some of said secondary channels for removing liquid therefrom laterally and uniformly in the form of downwardly directed liquid streams, said flow channels being disposed in at least two rows one about the other and extending from at least one side of a respective secondary channel.
Claim 2
Dependent Claim
100 words
A liquid distributor for an exchange column comprising an open main channel for receiving a flow of liquid; a plurality of secondary open channels disposed at spaced apart intervals and in communication with said main channel to individually receive a flow of liquid therefrom; and a plurality of flow channels connected to at least some of said secondary channels for removing liquid therefrom laterally and uniformly in the form of downwardly directed liquid streams, said flow channels being disposed in at least two rows one about the other and extending from at least one side of a respective secondary channel.
