Nuclear Magnetic Resonance for Measuring Gas Energy Content

摘要

The research is directed toward evaluating the feasibility of using nuclear magnetic resonance (NMR) to measure gas energy content and density. The hydrogen NMR properties of pure hydrocarbon gases, natural gases and mixtures of gases were measured over wide ranges of temperature and pressure. The data were analyzed to determine the potential and limitations of NMR for determining the calorific value of the gas, the composition and gas density. Results are very favorable to the practical use of simple NMR apparatus for online measurements of gas energy content, density and compressibility factors. References obtained during a literature search are listed.
