Oxides
Unlike PM and VOCs, control of sulfur oxides are largely chemical
rather than physical (cyclones, ESPs, filters, vapor capture,
condensation, adsorption). Sulfur and nitrogen oxides have many
sources and they are respiratory irritants, principal causes of
acid rain. 18:52 Elementary oxidation and reduction of S and
N

S is the sixteenth most abundant element in the earth crust (260
ppm) Sulfur in the earth crust exist mostly in the form of sulfates
CaSO4.2H2O: gypsum dihydrate Chemically inert, slightly water
soluble, nontoxic 18:52 Sulfur in the fuel Coal (0.5 to 3 %) Oil
