Abstract

We have designed and implemented an analytical calculation model with which we can real-time determine the composition of gas mixtures. The model is based upon a multi-parameter flow measurement system, consisting of a Coriolis and thermal flow sensor, a density meter and a pressure sensor. The system enables direct measurement of flow rate and physical properties of gas mixtures, including density, viscosity and heat capacity. We demonstrated real-time composition determination of binary and ternary gas mixtures. For fuel gases, we demonstrated real-time determination of the energy content (Wobbe index) of the gas mixture from its composition and density.
