An enclosure is positioned at a site with a fugitive gas source, such as a wellhead. A separator is located in the enclosure to remove liquid from the fugitive gas. A catalytic heater is located in the enclosure and coupled to the separator to react with the fugitive gas and produce heat in the enclosure. A pilot gas source can provide pilot gas to the catalytic heater. ## Claims ### Claim 1 A fugitive gas remediation (FGR) system for eliminating fugitive gas, the system comprising: a) an enclosure configured to be positionable at a site with a fugitive gas source;
