Argon makes up about percent of the Earth's atmosphere . Argon is not a greenhouse gas because it allows the sun light radiations to pass through them which
3. R-410A: This is a non-ozone-depleting refrigerant commonly used in newer air conditioning systems. It has a relatively low GWP compared to some other alternatives, but it is still a greenhouse gas and efforts are being made to develop even more sustainable options. ...
Thus although methane is a potent greenhouse gas, its effect is relatively short-lived. Nitrous oxide is destroyed in the stratosphere and removed from the atmosphere more slowly than methane, persisting for around 114 years. Compounds containing chlorine and/or fluorine (CFCs, HCFCs, HFCs, PFCs...
Chemically speaking, a hydrocarbon [HC] is an elemental compound of hydrogen and carbon that occurs naturally and is found in high concentrations in crude oil. Used as a modern refrigerant, non-toxic hydrocarbons are an environmentally friendly alternative to CFC/HCFC/HFC fluorocarbons linked to oz...
GREENHOUSE GASES Carbon dioxide, Methane, Nitrogen oxide, HCFCs: caused mainly by the burning of fossil fuels in electricity generation, transport, heating, industry and construction. Also caused by livestock, agriculture (mainly rice farming), wastewater treatment and landfills among others. ...
99.5% Purity Propane Gas C3H8 Product Description High-purity propane is mainly used as organic chemical raw materials, chemical solvents, electronic semiconductors and refrigerants. As a refrigerant, R290 has no damage to the ozone layer and has a very small greenhouse effect. It i...
Such a belief would stand unchallenged if only greenhouse gas emissions from production processes are concerned. This is because the electric and electronic industry emits far less green house gases during the manufacturing process than other industries. However as electric and electronic products are ...
In the study published inProceedings of the National Academy of Sciences, researchers used the IIASA Greenhouse Gas—Air Pollution Interactions and Synergies (GAINS) model to compare the baseline halogenated refrigerant emission scenarios with scenarios of switching to HFC-32 or propane. While the switch...
Water vapor is the most important greenhouse gas, and carbon dioxide is the second most important one. Methane, nitrous oxide, ozone and several other gases present in the atmosphere in small amounts also contribute to the greenhouse effect. ...
is adequate, easily accessible and flexible; and the Copenhagen agreement to help reduce concentrations of CO2 in the atmosphere to no more than 350 parts per million; implying the need for a 40% global greenhouse gas emissions reduction by 2020 from 1990 levels and an 80% emissions reduction ...
