ISO6976.2016: Calorific Values and Properties of Natural Gas per ISO 6976:2016

Description

Calculates calorific values (gross and net, molar, mass and volumetric bases), density, relative density, and Wobbe indices together with their standard uncertainties from natural gas composition, following ISO 6976:2016 "Natural Gas — Calculation of calorific values, density, relative density and Wobbe indices from composition".

Details

Uncertainty propagation is implemented according to Annex B of that standard (variance-covariance method).

**Application restrictions (ISO 6976:2016 §5):** * Combustion temperature: 0, 15, 15.55 (60 °F), 20, or 25 °C. * Volume reference temperature: 0, 15, 15.55 (60 °F), or 20 °C. * Reference pressure: 90–110 kPa. * Compression factor Z must be > 0.9.
