Inert Gas and Fuel Gas Influence on the Pressure Limits of Stability of Acetylene

Chemically unstable gases obtained in many processes of, for example, the chemical and petrochemical industries, can decompose explosively also in the absence of oxidizing agents. In order to avoid hazards resulting from explosion reactions, safety measures need to be developed. Key to such methods is the knowledge of stability limits of unstable gases. In the present paper, an experimental method for determining the pressure limits of stability of unstable gases and gas mixtures is presented. It has proved useful when examining C2H2/inert gas and C2H2/fuel gas mixtures.
