US Classification:

702 28

Abstract:

Thermodynamic properties of a natural gas stream can be determined in real time utilizing modeling algorithms in conjunction with one or more sensors for quantifying physical and chemical properties of the natural gas. A first data signal produced by a first sensor can include intensity as a function of wavelength. At least one region in the wavelength range outside of a selected absorption transition can be fitted to a function to obtain a zero-absorption baseline, and a carbon dioxide concentration can be determined based on a line strength at the selected absorption transition corrected by the zero-absorption baseline. A total hydrocarbon concentration in the gas stream can be inferred based on a database of characteristic natural gas concentrations, and an algorithm can be implemented that determines an energy content of the gas stream. Related techniques, apparatus, systems, and articles are also described.

G01N 33/28

Abstract:

Systems and methods for generating a Methane number for a compressed natural gas fuel by obtaining compositional data from one or more particular analyzers and applying the obtained compositional data to one or more selectable Methane number generation protocols. The systems and methods can include refining of the compressed natural gas fuel to meet a predetermined Methane number.
