Mass Transfer - Engineering
Q1: The overall mass transfer co-efficient for the absorption of SO2 in air with dilute NaOH solution can be increased substantially byA increasing the gas film co-efficient.
B increasing the liquid film co-efficient.
C increasing the total pressure.
D decreasing the total pressure.
ANS:A - increasing the gas film co-efficient. Increasing the gas film coefficient involves enhancing the efficiency of mass transfer between the gas phase (containing SO2) and the liquid phase (containing dilute NaOH solution) by reducing the resistance to mass transfer in the gas film. Here's how increasing the gas film coefficient can be achieved and why it improves mass transfer:
