The overall aim of the project is to enable the large scale roll-out of liquefied natural gas (LNG) and liquefied biogas (LBG) as a transport fuel. It also presents an essential step towards the development of measurement traceability for large scale LNG custody transfer applications. The custody transfer measurements of flow and composition should therefore be underpinned in a clear and transparent metrological infrastructure, and properties which are important for the use as a fuel, especially the density and the methane number (MN).
The proposed project will combine the expertise from industry, instrument manufacturers and research institutes to establish the necessary test facilities and validation methods. The outcome will be implemented in various relevant written standards to enable and promote the use of LNG and LBG as a transport fuel.
The overall aim of the project is to enable the large scale roll-out of liquefied natural gas (LNG) and liquefied biogas (LBG) as a transport fuel.
The specific objectives of this JRP to reach this are:
- To reduce the uncertainty of LNG flow meter calibration as well as to study and quantify the effect of flow disturbances, installation effects and the presence of multiphase flows on the measurement uncertainty. This enables meeting the uncertainty demands in field measurements.
- To perform feasibility study to determine how the existing facility can be best upgraded to meet the customer demand in small and mid scale applications.
- • Build a cryogenic liquefier to produce metrologically traceable LNG reference standards for the calibration of cryogenic liquid mixture composition. New techniques for online density and speed of sound determination incl. the respective uncertainties will be established.
- To develop a method to provide traceable mass measurements for particles on a filter collected in a stream of LNG or LBG gas and to assess the effect of ambient particulates on filter preparation for particle measurements in LNG and/or LBG.
- Develop and validate sensors and new analytical methods for the determination of the methane number (MN) and methane slip (MS) and verify these methods with engine tests.
- To make available the latest developed expertise and knowledge in various ISO standards and OIML recommendations.
