ABSTRACT:
Apparatus for contacting a liquid reaction solution with a gas in separate reaction chambers within a single reaction vessel wherein the liquid reaction solution is continuously circulated between a first reaction chamber and a second reaction chamber 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 said chamber, and said gas supply means including flow control means whereby the rate of upward flow of gas in one of the chambers is greater than the rate of upward 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 upward flow of liquid reaction solution and gas in the one chamber and downward 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.
