Abstract

This article presents a general description of the technical program of a work package related to the EMRP joint research project (JRP) ENG01 GAS supported by EURAMET and the European Commission as part of the targeted programme Energy (2009). The JRP “Characterisation of Energy Gases” proposes to put in place the necessary metrology infrastructure to enable the “interchangeability” of energy gases so that gaseous fuels from non-conventional sources can access gas grids across the EU. Four-funded European JRP partners participate to the work package dedicated to direct measurement of the energy content of non-conventional gases as biogas or coal bed methane by calorimetry. Energy content measurements with calorimetry ensure validation of the indirect method (gas chromatography) generally adopted by operators for on-site gas control. A reference gas calorimeter and different field calorimeters will be used to measure the energy content of real samples of non-conventional gases. Results will then be compared with indirect measurements. The work package will also focus on development of novel methods for density (needed for Wobbe index calculation) and thermophysical property as heat capacity of these gases.
