Apparatus for withdrawing a gas from a source and conditioning the gas for subsequent analysis for total reduced sulfur content comprising a gas probe having an inlet for a stream of gas and an outlet therefor, a conduit having means to provide heat to a gas stream flowing therein extending from the probe outlet to a condenser for cooling the gas and condensing out water, a second conduit from the condenser to a vacuum which causes a gas stream to enter the probe and flow through the heatable conduit to the condenser and then the second conduit, a third conduit for delivering a stream of gas from the second conduit to a scrubber to wash the gas stream with a scrubbing liquid, a demistor for removing the gas stream from the scrubber and separating entrained scrubbing liquid, and a pump for pumping the scrubbed gas stream, from which scrubbing liquid has been removed, to an analyzer and flow meter. A method of conditioning the gas for analysis using the apparatus is also disclosed.

Apparatus for withdrawing a gas from a source and conditioning the gas for subsequent analysis for total reduced sulfur content, which comprises: a gas probe having an inlet for a stream of gas and an outlet therefor, a conduit, having electrical resistance means to provide heat to a gas stream flowing therein, extending from the probe outlet to a condenser, said condenser having a passage through which a gas stream can flow and be cooled by indirect heat exchange with a cooling fluid and vapor in the gas condensed to liquid, a second conduit from the condensor passage to a means for producing a vacuum which causes a gas stream to enter the probe and flow through the heatable conduit to and through the condenser passage and the second conduit, a third conduit for delivering a stream of gas from the second conduit to a scrubber to wash the gas stream with a scrubbing liquid, means for removing the gas stream from the scrubber and separating entrained scrubbing liquid, and means for pumping the scrubbed gas stream, from which scrubbing liquid has been removed, to an analyzer and flow meter. A method comprising: withdrawing a stream of hot gas containing water vapor from a source believed to contain a gaseous reduced sulfur content, continuously maintaining the withdrawn stream of hot gas at a temperature above the dew point temperature of the gas, feeding the stream of hot gas to a condenser to condense the water vapor from the gas, removing the condensed water with the stream of previously hot but now cooled gas from the condenser, diverting a minor portion of the cooled gas stream, substantially devoid of water, to a scrubber, scrubbing the cooled gas stream in the scrubber with a scrubbing liquid, withdrawing the scrubbed gas stream from the scrubber, separating residual scrubbing liquid from the scrubbed gas stream, and feeding the scrubbed gas stream to an analyzer and flow meter to determine the total reduced sulfur content in the gas stream.
