Question

For the Absorber design, the plotting with mole ratio helps to find the

(a) Slope of operating line

(b) Slope of equilibrium curve

(c) Minimum number of trays

(d) Maximum number of trays

I have been asked this question in a dream while sleeping

My question comes from Operating Line Concept for Absorption topic in section Gas Absorption of Mass Transfer

Answer 1

The correct option is (a) Slope of operating line

The best explanation: The plot with mole fraction will give an operating line as a curve; it will be very difficult to find the slope of the operating line. Therefore the use of mole ratio plot will give us a liner operating line.
