Commodity natural gas is substantially free of sulfur compounds the terms sweet and sour are used to denote the absence or presence of H2S. Some wells, however, deliver gas containing levels of hydrogen sulfide and other sulfur compounds (e.g., thiophenes, mercaptans, and organic sulfides) that must be removed before transfer to commercial pipelines. Pipeline-company contracts typically specify maximum allowable limits of impurities H2S and total sulfur compounds seldom exceed 0.023 and 0.46 g/m (1.0 and 20.0 gr/100 std ft ), respectively. The majority of pipeline companies responding to a 1994 survey limited H2S to less than 0.007 g/m (0.3 gr/100 std ft ), but a slightly smaller number continued specifying 0.023 g/m, in accord with an American Gas Association 1971 recommendation.

Figure 1-28. Two versions of Warren Rehm s separate site theory illustrating the problem of accounting for the isotonicity of the acid secretion. On the left, the scheme proposes that chloride ions are secreted by the surface epithelial cells and hydrogen ions by the parietal cells. On the right, the scheme proposes that the hydrogen ions are secreted by the surface epithelial cells and the chloride ions by the parietal cells. See text for further explanation. (From Rehm WS.
