Boundary conditions for passive gas detection quantified and applications identified

In order to perform remote gas detection of methane gas from distribution pipe systems or from the environment it is important to know gas leak behaviour during different thermal background and ambient weather conditions.

Using a combination of an especially constructed gas field test site, a stationary weather station at the site, and detailed field measurement of specific flow, delta T, weather and radiation conditions, direct at the gas leak source, it has been possible to create a field reference database of background conditions and limits for passive gas imaging. It should be noted that the passive gas imaging systems used are not constructed for passive gas imaging, but for surveillance applications. This means that the results could not be used to predict the advantages and limitations for passive gas imaging in general, but for the systems used.

However, the database created does provide adequate information about gas behaviour and could be used as input when constructing or testing remote detection systems or when developing methods and instructions how and when to use remote gas detection technologies. The results from the passive gas imaging surveys performed, and the data base have been incorporated in for instance the training packages described in another part of the project. The database will finally be upgraded with data from passive gas imaging of gas leaks simulated during snow conditions, performed during the extended 6-month period of the VOGUE-project.
