ABSTRACT OF THE DISCLOSURE A process for reacting a circulating liquid reaction solution with a gas in separate reaction zones within a single reaction vessel wherein the liquid reaction solution is con- tinuously circulated between a first reaction zone and a second reaction zone within the reaction vessel but providing at least two side-by-side reaction chambers in open flow communication at their upper and lower ends with a gas supply means associated with each said chamber for introducing a gas in a finely divided form into the lower ends of each control means whereby the rate of upwardly flow of gas in one of the chambers is greater than the rate of upwardly flow of gas in the other chamber so as to lower the density of the liquid reaction solution in the one chamber and provide continuous upwardly flow of liquid reaction solution and gas in the one chamber and downwardly flow of liquid reaction solution countercurrent to the flow of gas in the other chamber. The process and apparatus are particularly adapted for continuously carrying out two distinct chemical reactions between a liquid reaction solution and two different gases in a single reaction vessel, such as a catalytic oxidation-reduction process for removing hydrogen sulfide gas from a process gas stream.
