Abstract

Method 11 (Federal Register, 39, pp. 9321-9323, March 8, 1974), 'Determination of Hydrogen Sulfide Emissions from Stationary Sources,' is subject to serious mercaptan interference. Several alternate absorbing reagents were evaluated, including several salts of cadmium and zinc. The solution pH was adjusted to obtain a high collection efficiency for H2S without also collecting mercaptans. The most selective absorbing solution was 0.16 M cadmium sulfate at a pH of 3.0. The H2S collection efficiency was 96 percent, and mercaptan concentration equal to the H2S gave results about 5 percent high. The effect of 14 variables on the analysis were evaluated in a ruggedness test. The optimized procedure was then field tested at three refineries under a variety of conditions. The laboratory and field tests were then used to write a final version of the procedure.
