4-Way Inspection Services is currently inspecting various facilities and pipelines in and around the Alberta and BC regions with the use of industry leading FLIR equipment. The cameras use infrared imaging technology to produce video images in which invisible gases escaping from leak sources can be clearly identified.
What Are Fugitive Emissions?
Fugitive emissions are emissions of gases or vapors from pressurized equipment due to leaks and other unintended or irregular releases of gases, mostly from industrial activities. As well as the economic cost of lost commodities, fugitive emissions contribute to air pollution and climate change.
Where Can Fugitive Emissions Be Detected?
Leaks from pressurized process equipment generally occur through valves, pipe connections, mechanical seals, or related equipment. Fugitive emissions also occur at evaporative sources such as waste water treatment ponds and storage tanks. Because of the huge number of potential leak sources at large industrial facilities and the difficulties in detecting and repairing some leaks, fugitive emissions can be a significant proportion of total emissions.
