Abstract: A gas-liquid column and method having improved mist elimination particularly for the treatment of corrosive fluids which comprises directly introducing a liquid from a liquid distributor resting on a top structured packing layer into the upright flow passage of the structured packing to provide the initial gas-liquid contact within the top structured packing layer, thereby reducing mist and spray and particularly useful where corrosive fluids are used.

Abstract: A multiple level distributor and method for the distribution of a downwardly flowing liquid in a gas-liquid contact column and the upward flow of a gas within the gas-liquid column and which distributor comprises a trough type distributor having a plurality of holes therein, the holes arranged in at least two different levels of height from the bottom of the trough type distributor, the number and size of the holes and the height of the holes so arranged to provide for control of the liquid turndown and the liquid flow of the downwardly flowing liquid in the gas-liquid column.
