The exit gas from a drier in a chemical plant consists of an N2-CS2 mixture (30) containing 3.0 mole% CS2 . Using a tray column, 97% of CS2 is to be absorbed by countercurrent contact with an oil stream. The column operates isothermally at24°C, at which for dilute CS2, the equilibrium curve can be simplified as Y = 0.46 X. The N2-CS2 gas mixture enters the column at rate of 6.0 kmol/hr, and the oil enters the column free of CS2. If L'/V' is 1.3 times L'min/V', determine the required theoretical number of stages using the Algebraic or Kremser method.

Question

The exit gas from a drier in a chemical plant consists of an N2-CS2 mixture (30) containing 3.0 mole% CS2 . Using a tray column, 97% of CS2 is to be absorbed by countercurrent contact with an oil stream. The column operates isothermally at
24°C, at which for dilute CS2, the equilibrium curve can be simplified as Y = 0.46 X.

The N2-CS2 gas mixture enters the column at rate of 6.0 kmol/hr, and the oil enters the column free of CS2. If L'/V' is 1.3 times L'min/V', determine the required theoretical number of stages using the Algebraic or Kremser method.
