WebSep 29, 2024 · Soil vapor as methane can migrate underground, and accumulate inside buildings over time. Methane Soil Gas Tests are designed to screen the soil under properties for combustible hydrocarbon content. Based on the results of a methane soil test, a Methane Mitigation System can be designed to prevent its intrusion into buildings. WebHydrocarbon gas liquids (HGLs) are hydrocarbons that occur as gases at atmospheric pressure and as liquids under higher pressures. HGLs can also be liquefied by cooling. The specific pressures and temperatures at which the gases liquefy vary by the type of HGLs. HGLs may be described as being light or heavy according to the number of carbon ...
