Leak Detection and Repair ( LDAR ) method constitutes a key element of strategies aimed at minimizing emissions of volatile organic compounds (VOCs) from industrial installations. Among potential emission sources, process valves play a particularly important role due to their large numbers, wide variety of designs, and placement within process lines, all of which result in a significant contribution to the overall emission balance. Leakages occurring in valves, flanged connections, and other valve components may lead to raw material losses as well as the release of hazardous substances into the atmosphere.
