18、,-,- CGA G-122004 COMPRESSED GAS ASSOCIATION, INC. PAGE 1 1 Introduction This publication is one of a series compiled by the Compressed Gas Association, Inc. (CGA) in response to demand for information relating to the properties, transportation, storage, and handling of compressed gases. 2 Scope Thi
19、s publication provides information regarding the properties, manufacture, shipping, storage, handling, and use of hydrogen sulfide. It also describes many of the related regulatory requirements and safe practices in the United States and Canada. This information is intended to complement but not sup
20、plant national, state, provin- cial, territorial, municipal, and insurance company codes and requirements. The information in this publication is intended for use by hydrogen sulfide shippers, carriers, distributors, re- packagers, consumers, equipment designers or installers, safety administrators,
21、 and others desiring an intro- ductory knowledge to the subject. Anyone requiring more detailed or specialized information should consult their hydrogen sulfide supplier. Also see the references listed in Section 12. 3 Manufacture, properties, and uses 3.1 Manufacture Hydrogen sulfide is widespread
22、in nature, occurring to some extent in most petroleum and gas deposits, gey- sers and hot springs, and in some mines. Generally, it is associated with the anaerobic decay of dead organ- isms and is released from sewers, swamps, and lake bottoms in considerable amounts. Hydrogen sulfide does not rema
23、in in the atmosphere long because it is a part of the natural sulfur cycle and is quickly oxidized to sul- fate and returned to the soil and water. In the laboratory, hydrogen sulfide is generated by the action of an acid on iron sulfide or by warming a solution of a thioacetamide. Commercially, hyd
24、rogen sulfide is usually produced by one of the following methods: the reaction of a sulfide or bisulfide with an inorganic acid; the union of sulfur and hydrogen at high temperature and pressure; or the separation of the native compound from hydrocarbons in petroleum and natural gas processing.
