Oxides of Sulphur

Oxides of Sulphur ( SOX)

Sources of Oxides of Sulphur ( SOX)
a) Combustion of coal
b) Combustion of petroleum products.
c) Burning of refuse
d) Oil refining
e) From power house
f) Sulphuric acid plant
g) Metallurgical operation.
h) Domestic burning of fuel.


Characterisrics of Oxides of Sulphur ( SOX)
a) Comprises of SO2 is 97 to 99 % and SO3 is 3 to 1 %.
b) SO2 is colourless, heavy, water soluble gas with pungent smell and irritating odour.
c) SO2 is rapidly diffusing, acid forming, oxidizing agent.
d) React with water forming H2SO3 and H2SO4 both of which can react with organic matter, metals and other materials.


Biochemical effects of Oxides of Sulphur ( SOX)
a) Absorbs quickly and irritates the upper respiratory tract.
b) Reacts with cellular constituent, example is enzyme.
c) The sulphuric acid forms lowers pH, which impairs enzymatic funtions and destroys various functional molecules.
d) Lung clearance and impaired pulmonary function are occurred.

Control of Oxides of Sulphur ( SOX)
a) Absorb SO2 is from the air.
b) Separate Sulphur from fuel.
c) Minimize the use of Sulphur fuel.
d) Use of natural gas instead of Sulphur fuel.
