Mass Transfer
12.
Pick out the wrong statement.
When the concentration difference for the mass transfer becomes zero at the bottom of the gas absorption tower, then the upper end of the operating line touches the equilibrium curve.
The average distance between the operating line and equilibrium line is large, when the liquid-gas ratio is also large in case of a counter current gas absorption tower.
The operating line lies above the equilibrium curve in case of a gas desorber.
With decrease in the liquid flow rate for a fixed gas flow rate, the slope of the operating line decreases, in case of gas absorption process.

I think Option B is Not a correct statement.

As L/G increases, the operating line approaches equilibrium, → less average distance.

Yes, option B is wrong because the large ratio of L/G operating line is close to the equilibrium curve.
