Measurement and Prediction of the Inert Gas Influence on Explosion Limits for Ethylene/Nitrogen/Air and Ethylene/Carbon‐Dioxide/Air Mixtures at Elevated Pressures

To determine the explosion limits of combustible gas/inert-gas/air mixtures at elevated initial pressures and/or temperatures, a high experimental effort is necessary. No standard test method exists and values are rarely to find in the literature. In order to reduce the large number of experiments, models suitable for simulating the inert gas influence on explosion limits at elevated pressure have been developed. In this work, an experimental method to determine the explosion limits at elevated pressures and the simulation of the inert gas influence of nitrogen and carbon dioxide on the explosion limits of C 2 H 4 /air mixtures are presented.
