1. An apparatus comprising:
a first pressure vessel configured to generate a sweet gas from a sour gas stream via an oxidation-reduction reaction that results in formation of surface foam and a non-gaseous multi-phase mixture comprising an emulsion, the first pressure vessel comprising:
a first inlet for receiving the sour gas stream;
a first outlet for outputting the sweet gas; and
a primary stage phase separator comprising a second inlet disposed inside the first pressure vessel and a second outlet for outputting a separated non-gaseous multi-phase mixture, the second inlet located such that the surface foam and the separated non-gaseous multi-phase mixture flow into a partially gas-filled upper section of the primary stage phase separator and freefall under force of gravity into an aqueous multi-phase mixture maintained at a target level of a lower section of the primary stage phase separator, the target level selected such that the surface foam and the emulsion are mechanically broken down by abrupt deceleration upon contacting the aqueous multi-phase mixture at the target level.
