A. 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
B. The average distance between the operating line and equilibrium line is large, when the liquidgas
ratio is also large in case of a counter current gas absorption tower
C. The operating line lies above the equilibrium curve in case of a gas desorber
D. 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
Correct Answer: The operating line lies above the equilibrium curve in case of a gas desorber ✔
