sufficient to cause a substantial amount of the hydrogen sulfide and volatile mercaptans to pass from the treated condensate 30 in the vessel to a gas phase generally speaking it will be sufficient to reduce the pressure to about or slightly above atmospheric pressure or 0 psig the temperature of the condensate is not believed to be critical to the invention and may vary within wide limits provided the temperature is not such that an excessive amount of carbon dioxide applied to conduit 14 is required to reduce the ph to the desired range condensate temperatures in the range of from about 18 u00b0 to about 99 u00b0 c are believed to be suitable a gaseous stream or vapor phase containing hydrogen sulfide volatile mercaptans and possibly an amount of carbon dioxide is collected from the treated condensate 30 and vented from the vessel 26 through conduit 32 and control valve 34 for further processing recycle or disposal the treated condensate 30 having a substantially reduced concentration of dissolved hydrogen sulfide volatile mercaptans and other volatile sulfurous components is fed from vessel 26 through conduit 36 to pump 38 for recycle further treatment or disposal in particular the treated condensate substantially freed of hydrogen sulfide and volatile mercaptans and at a substantially reduced.
