941LS Liquid Sulfur Analyzer
Safety and environmental concerns require attention to the residual H2S present in Claus-produced liquid sulfur product. Whether or not sulfur degassing is utilized, it can be important to monitor the amount of H2S contained in the sulfur to assure safe shipping and handling. In conjunction with a major university, Brimstone has developed and now markets an analytical device capable of this measurement.
941LS Liquid Sulfur Analyzer
The measurement of H2S in liquid sulfur is complicated somewhat by the fact that it exists in two distinct forms, H2S {dissolved gas) and H2Sx (dissolved polymer), which are in equilibrium with each other and with-elemental sulfur (S8). The use of state-of-the-art Fourier transform an infrared spectrometer analytical system allows the resolution of the H2S and H2Sx absorptions giving accurate (±10% of the measured value) determinations of total H2S in the 0 - 350 ppmw range with quantification down to 2 ppmw. These analyzers are currently available in a lab-based version, but design has begun on an on stream field based analyzer system.
