Is methane Non Volatile?

Is methane Non Volatile?

Organic chemical compounds, excluding methane, that under normal conditions can vaporise and enter the atmosphere. NMVOCs include such compounds as benzene, xylene, propane and butane. NMVOCs are mainly emitted from transportation, industrial processes and use of organic solvents.

Is methanol a VOC?

Methanol is considered a volatile organic compound by the National Pollutant Inventory.

What is classified as a VOC?

” Volatile organic compounds (VOC) means any compound of carbon, excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, and ammonium carbonate, which participates in atmospheric photochemical reactions.

What are Nmvoc emissions?

NMVOCs are emitted to air as combustion products, as vapour arising from petrol and solvent use and from numerous other sources. NMVOCs are involved in the photochemical production of ozone and secondary organic aerosols in the atmosphere over a large spatial scale.

Do VOCs contribute to global warming?

A consequence of the uncontrolled emission of VOCs, in general, and solvents, in particular, is that they may act as greenhouse gases and hence there may be climate change consequences.

Why is methane not a VOC?

Essentially, NMVOCs are identical to volatile organic compounds (VOCs), but with methane excluded. The exclusion of methane is necessary due to its relatively high ambient concentration in comparison to other atmospheric species and its relative inertness.
