Abstract |
A collaborative test was run of the revised Method 11 procedures that was developed in Volume I. Ten collaborators were selected from a total of 24 interested organizations. Part of the screening process was to require each potential collaborator to analyze a set of liquid samples in accordance with the procedure. A test manifold was constructed which could simulate typical refinery fuel gas streams. During February 22 to 27, 1976, a total of 16 runs at three different H2S levels were made, as well as a series of standard sample analyses. MRI then made a statistical analysis of the collaborators' results. Without mercaptans present, results averaged 4 percent low with a standard deviation of 2 percent for any single collaborator and a standard deviation between collaborators of 4 percent. With mercaptans present at 150 ppm, precision was unaffected but the results varied from 2 percent low to 14 percent high at H2S concentrations of 400 and 100 mg/dscm. The tentative procedure was found to be adequately written for those knowledgeable of sampling and analysis techniques. |
