  1. An effluent gas from a food processing industry with a flow rate of 1000 mol/h is to be processed. It contains 10mol% SO2 and the remaining balance of an inert gas. Due to environmental restriction, the industry should absorb the SO2 in the original effluent with 92% of absorption efficiency before emission to the environment. For this task, pure water is employed as a solvent since SO2 is highly soluble in water. The equilibrium data is given hereunder in molar ratio. The operating line is a straight line and is represented  by

Determine:

  1. The amount of solute and inert gas in feed
  2. The inlet and outlet concentration of solute in mole ratio

 in the gas phase

  1. The inlet and outlet concentration of solute in mole ratio

 in the liquid phase

  1. Theoretical number of stages required
  2. In this case or generally in absorption, the operating line lays above the equilibrium curve/line whereas in distillation and stripping the reverse is true. Why?
