Volume flow calculations on gas leaks imaged with infrared gas-correlation

Sandsten, Jonas LU and Andersson, Martin LU (2012) In Optics Express 20(18). p.20318-20329
Abstract
Two methods for volume flow calculation from images of methane leakages to the atmosphere are presented. The images contain calibrated gas concentration x path length pixel information, and are processed with a block matching method and a theoretical velocity field method. Results from known methane flow in two laboratory setups and one unknown real leakage from a gas processing plant are compared with the image processing methods. The methods are generic and can be implemented in common infrared systems for gas visualization. This work provides a new tool for estimating and reporting volume flow emissions from gas processing plants to the authorities. (C) 2012 Optical Society of America
