1. A system for analyzing a hydrocarbon gas containing hydrogen sulfide (H2S), mercaptans, and one or more other sulfur compounds, the system comprising:
a branched fluid conduit that comprises a first branch and a second branch, wherein the branched fluid conduit splits the hydrocarbon gas into a first gas stream that flows through the first branch and a second gas stream that flows through the second branch;
a first scrubber that receives the first gas stream from the first branch, the first scrubber comprising a first non-aqueous scrubber material that removes the H2S from the first gas stream to produce a first scrubbed gas, wherein the first non-aqueous scrubber material comprises at least one of a carbonate salt, a bicarbonate salt, a metal oxide, and an amine; and
a second scrubber that receives the second gas stream from the second branch, the second scrubber comprising a second non-aqueous scrubber material that removes the H2S and mercaptans from the second gas stream to produce a second scrubbed gas, wherein the second non-aqueous scrubber material comprises at least one of an alkali metal hydroxide, an alkaline earth metal hydroxide, and an iodate salt;
at least one gas sensor in fluid communication with the first scrubber and the second scrubber, the at least one gas sensor sensing at least one sulfur compound of the one or more other sulfur compounds in the first scrubbed gas and the second scrubbed gas.
