ABSTRACT:
Fluid distribution systems, and particularly those for distributing liquids into apparatuses containing modules used to carry out vapor-liquid contacting, are described. Representative liquid distribution systems comprise an extended trough having a plurality of outlet spouts that are aligned for distribution into a plurality of downcomers. The downcomers may be in non-parallel (e.g., orthogonal) alignment with respect to the trough and/or the number of troughs may be less than the number of downcomers to which fluid is distributed.
