ABSTRACT:
In a system for recovering liquefiable components from well head gases and like gaseous mixtures, a vapor liquid contact apparatus which comprises a combination of a tower shell and liquid spray unit with an absorption unit inside of and supported by the shell so as to permit relative movement of the shell and component parts of the absorption unit.
The absorption unit is formed of a multiplicity of superposed plates connected by vertical gas and liquid conduits, a peripheral annular aperture surrounding each plate. In the absorption unit the chambers formed between plates are connected by the vertical liquid conduits for flow of liquid down through the chambers and by the vertical gas conduits for flow of gas up through the chambers, chamber to chamber, the gas conduits being located at the periphery of the plates and adjacent the tower shell.
Gas enters each chamber of the absorption unit at the chamber top, adjacent one side edge, and flows across and down the chamber to leave at the chamber bottom adjacent an opposing side edge. The liquid sprayed into the chamber is directed so as to divert gas flow toward the side and bottom walls of the chamber. Droplets entrained in the gas become absorbed in liquid films that are present on the side and bottom walls of the chamber. The gaseous mixtures passing up through the vapor liquid contact apparatus becomes reduced in liquefiable components.
