P. If it is assumed that air contains 23.15 percent oxygen by mass, then the amount of air required for the complete oxidation of 1 kg of carbon would be equal to 11.25kg.
Q. The anaerobic digestion will require an optimum C/N ratio of about 30 – 50.
R. Pulverization refers to the action of cutting and tearing, whereas shredding refers to the action of crushing and grinding.
S. Electrostatic precipitator is also installed in the incineration plant to reduce air pollution, particularly due to the emission of dioxin.
T. Pyrolysis is highly exothermic in nature and hence also known as destructive distillation.
