Overview of Greenhouse Gases | Greenhouse Gas (GHG) Emissions

Apr 14, 2021 · Larger emissions of greenhouse gases lead to higher concentrations in the atmosphere. Greenhouse gas concentrations are measured in parts per million, parts per billion, and even parts per trillion. One part per million is equivalent to one drop of water diluted into about 13 gallons of liquid (roughly the fuel tank of a compact car).Get price

EPRI’s SF Management Program - US EPA

In 1996, EPRI purchased a custom-built version of a real-time Sulfr hexafluoride gas leak visualization system normally used for assembly line leak testing. The technology, known as “GasVue,” uses an infrared laser camera to visualize Sulfr hexafluoride gas, which is transparent in visible light but can be seen with infrared light.Get price

PGE Phases Out Sulfr hexafluoride Greenhouse Gas | TD World

Feb 21, 2019 · Like carbon dioxide, SF 6 is a greenhouse gas. While CO 2 has a global warming potential (GWP) of one, SF 6 has a GWP of 23,500. Although PGE reduced its SF 6 leak rate to nearly 1%, this came with an extreme operating cost. Eliminating the use of SF 6 would eliminate future leaks and result in reduced operating cost.Get price
