A coal containing 2% sulfur is burned completely to ash in a brick kiln at a rate of 30 kg/min. The sulfur content in the ash was found to be 6% of the initial amount of sulfur present in the coal fed to the brick kiln. The molecular weights of S, H and O are 32, 1 and 16 g/mole, respectively. The annual rate of sulfur dioxide $ (S0_2) $ emission from the kiln (in tonnes/year, up to two decimal places) is ______
Pre-cursors to photochemical oxidants are
The concentration of Sulphur Dioxide (SO_{2}) in ambient atmosphere was measured as 30 $\mathrm{\mu}$g/m^{3}. Under the same conditions, the above SO_{2} concentration expressed in ppm is ___.
Given: P/(RT) = 41.6 mol/m^{3}; where, P = Pressure; T = Temperature; R = universal gas constant; Molecular Weight of SO_{2} = 64.
SO_{2} and CO adversely affect
