Craig O'Neill, Optical Gas Imaging and US Regulations,

From its inception nearly 15 years ago, Optical Gas Imaging (OGI) has steadily evolved from being classified as a little-known emerging technology to now being a well-understood and accepted fugitive emission solution. OGI has advanced beyond the classification of “alternative” regulatory technology to being widely accepted and regarded as one of the most cost-effective approaches for leak detection. OGI is even listed as a Best System for Emissions Reduction (BSER) in the 2016 NSPS OOOOa regulation. True cost-effectiveness has been shown in OGI’s ability to safely inspect difficult to monitor components, which have historically added to inspection man-hours and equipment expense, such as those required to build scaffolding or use personnel lift equipment. OGI has also been shown to reduce costs by allowing more components to be inspected in a shorter amount of time, effectively helping to find the larger (long-tail) leaks faster. Once known only as a qualitative leak detection technique, OGI can now quantify leaks via Quantitative Optical Gas Imaging (qOGI) analysis which further simplifies the visualization and measurement of gas emissions. Newer, lower-cost OGI detectors now allow for cost-effective continuous, autonomous leak detection complete with alarming and recording capabilities. Other advancements in OGI detectors have reduced power requirements which allow them to be used in UAV payloads where miles of pipe or other difficult to monitor components and equipment can be quickly and safely inspected. This paper will give more detail and insight into the progression and evolution of this exciting technology.
