| Abstract |
Several widely employed test methods for the iodimetric measurement of hydrogen sulfide in refinery fuel gases are shown to suffer from serious thiol interferences. An absorbing solution consisting of 0.16 M cadmium sulfate/sulfuric acid at pH 3.0 is shown to be effective for the collection of hydrogen sulfide in the 70-700 mg/cu m range and to be essentially free from interference by up to 1800 mg/cu m of methanethiol. When combined with a single 3 percent hydrogen peroxide impinger, sulfur dioxide interferences of up to 1,300 mg/cu m are also removed. No measureable interference results from the presence of carbon oxysulfide, ethene, dimethyl sulfoxide, or thiophene. Acetaldehyde and acetone are observed to interfere at the 2,400 and 48,000 mg/cu m level, respectively. It is proposed that the absorption solution described here be substituted for the cadmium hydroxide/cadmium sulfate mixture used in the EPA test method (Method 11) for determining the hydrogen sulfide content of refinery fuel gases. |
