One way to remove H2S is to treat the water with chlorine, in which case the following reaction occurs: The rate of this reaction is first order in each reactant. The rate constant for the disappearance of H2S at 28 ∘C is 3.5×10−2 M−1s−1.
WebMeasurement of hydrogen sulfide (H2S) is a critical practice for quality control and safety purposes. Without precise quantification of H2S in a process, efficient processing of crude oil is not possible. To maintain safety when transporting crude oil and condensate, measurement of the H2S content is vitally important.
