Author: Howard N. Lewis
Source: 1975 Appalachian Gas Measurement Short Course
Year Published: 1975
Abstract: I. Scope: Hydrogen Sulfide, H2S, in the natural gas stream is undesirable, as it is extremely corrosive to metal equipment with which it comes in contact. It has a deterious effect on catalysts in certain chemical processes and has a very offensive odor. There is a much greater toxic effect on people than with carbon monoxide, and the threshold limit value by American Conference of Governmental Industrial Hygienists (1972) is 10 PPM (7-8 hours). II. Methods of Field Testing A. Pump and detector tube method B. Lead acetate method C. Tutweiler method III. Pump and Detection Tube Method A. Basic apparatus 1. Included in the Unico No. 400 Gas Detector Kit are the pump, metal carrying case, spare parts, and operating manual.
