Analysis of Delta In-Out of natural gas distribution networks

G. Ficco et al.

Summary: Estimation of Unaccounted for Gas in natural gas networks has been widely debated recently, and this paper presents a theoretical study on the causes and analysis methodologies of Delta In-Out in natural gas distribution networks, with a focus on Italian networks. The study reveals a national average value of Delta In-Out around +1%, with significant variations based on network size and climatic zone.

A rigorous model to compute thermodynamic properties of natural gas without applying full component analysis

Shaghayegh Nazari et al.

Summary: The study uses a standard EOS to predict natural gas compressibility factor and density, estimating component analysis with Genetic Algorithm for further thermodynamic properties calculations. The model's reliability and accuracy are validated by comparing calculated data with experimental results, showing uncertainty figures within acceptable ranges.
