air
air pollutants
SO2
by volcani erruption cause acidic rain
SO3
by internal combustion engines cause acidic rain
NO2
by internal combustion engines cause acidic rain
NO
by lightning activity in air cause acidic rain
OZONE
by petrochemical reactions cause petrochemical smog
CH4
by decomposition of fossils of bacteria cause global warming
UNBURNT HYDROCARBONS
by internal combustion cause greenhouse effect and global warming
CO2
by complete combustion produce global warming and acidic rain
CFCS
by AC and refrigerators it convert O3 to O2
CO:
by incomplete cobustion produce poisonous gases
fractional distilation
air is compressed at 200 atm
joule thomson's effect: air is expanded and cooled and changed into liquid
removal of CO2 and H2O
compression and expansion is repeated
air is filtered
air is passed through fractional column where gases are seperated according to their B.P
components
nitrogen(78%)
oxygen(21%)
noble gases(1%)
Carbondioxide(0.03%)
boiling points of components of air
argon=-186C
oxygen=-183C
nitrogen=-196C
