As ever-expanding sources of natural gas converge on the industrialized world, companies and governments need to quickly and accurately assess the quality of gas flowing through the pipeline and/or being delivered to the consumer. Vergence is able to make this information accessible, in real-time like never before, so critical decisions can be made in a more timely and intelligent manner.
The Vergence GasPT2, designed by GL Industrial Services (GL) and licensed worldwide and exclusively to CUI Global, provides a low cost solution to measure gas quality. When connected to a natural gas system, the GASPT2 can provide a fast, accurate, close to real time measurement of physical gas properties such as thermal conductivity, speed of sound and carbon dioxide content. From these measurements it infers an effective gas mixture comprising five components: methane, ethane, propane, nitrogen, and measured carbon dioxide and then uses ISO6976 to calculate the gas quality characteristics of calorific value (CV), Wobbe index (WI), relative density (RD), and compression factor (Z).
