Study of the Properties of Numerous Odorants and Assessment of Their Effectiveness in Various Environmental Conditions to Alert People to the Presence of Natural Gas.

摘要

A study was conducted to provide present state-of-the-art information on the odorization of natural gas. The input data for the study came from three sources: A literature survey of past and present gas industry odorization practices, a questionnaire (Appendix A) submitted to those responsible for the gas industry's odorization programs,and a series of personal interviews with pertinent employees of individual gas companies and odorant suppliers. Tertiary butyl mercaptan blends are preferred over other commercial odorants. Nearly all companies check odor levels with odorometers. Titrators are most often used for continuous monitoring of odorant concentrations. Industry has indicated a general acceptance of present Federal regulations and recommends that further regulation be considered carefully in terms of its real contribution to safety.
