Infrared absorption chemical species tomography for monitoring fugitive emissions

加拿大巨大的化石燃料储备支撑着我们国家的经济繁荣。不幸的是，与上游石油和天然气行业相关的逃逸排放也占加拿大温室气体清单的很大一部分，并对石油和天然气工人以及广大加拿大人构成许多健康和安全风险。目前，工业依靠点源浓度测量来检测和定位逃逸排放，并依靠半经验算法来估计排放通量，但由于逃逸排放的高度局部性和间歇性，这些技术众所周知不可靠。因此，迫切需要一种新的工具，能够查明逃逸的排放源，并提供准确的排放通量估计，以便评估监管遵守情况并指导缓解战略。

Canada's enormous fossil fuel reserves underpin our national economic prosperity. Unfortunately, fugitive emissions associated with the upstream oil and gas industry also account a significant portion of Canada's greenhouse gas inventory, and pose numerous health and safety risks to oil and gas workers, and Canadians at large. Currently, industry relies on point source concentration measurements to detect and localize fugitive emissions, and semi-empirical algorithms to estimate emission fluxes, but these techniques are notoriously unreliable due to the highly localized and intermittent nature of fugitive emissions. Accordingly, there is a pressing need for a new tool that can pinpoint fugitive emission sources, and provide accurate emission flux estimates in order to assess regulatory compliance and guide mitigation strategies.
