Heating value, relative density and compression factor for dry or wet natural gas from composition Academic Article uri icon


  • Calculation of the custody transfer properties of natural gas from compositional analysis is relatively straightforward but requires levels of understanding in practice. Several myths exist concerning these properties which are harmless for technicians, but cause difficulty for engineers. In addition, the question of water in the gas and the air used to burn the gas is a complicating factor which requires careful analysis. This paper presents a recipe for calculating these properties from gas composition, including a rigorous analysis of water content. The results contained in this work are generally consistent with ISO Standard 6976, except with respect to water content and the fact that ISO 6976 is an international standard which requires a great deal of information which is not necessary for current purposes. © 1995.
