Analysis and quantification of H2S during deodorisation process in steam reforming units

摘要

Steam reforming is a process used to produce high amounts of hydrogen from methane. In this case, a superior quality of methane is needed to be purified from all odorant compounds present in natural gas. To ensure the accuracy of the deodorisation process.it is necessary to monitor the quantity of sulphur compounds emitted while being separated from the natural gas, however, until now, analysing this compound in such a humid and complex matrix has been problematic.Chromatotec solutions quantify hydrogen sulphide at high concentration (low ppm) samples taken directly from natural gas pipes and very low concentrations (low ppb) sample taken after deodorisation. This dual-range system works with two different volumes of sampling loops. The analyser automatically switches between the two sampling loops to avoid the saturation of the system and/or signal.
