Both oxygen (O2) and hydrogen sulfide (H2S) are present in varying concentrations in unrefined natural gas. Although most of the oxygen and hydrogen sulfide are removed during the refining process, trace amounts still remain. These trace remnants and their levels must be monitored and controlled to ensure gas quality standards, as well as prevent corrosion of pipeline materials and damage to handling and utilization equipment. This module will serve as an introduction to the equipment and methods used in determining the presence and concentrations of oxygen and hydrogen sulfide in a gas sample.
