Mass Transfer If f = moles of vapour present per mole of feed, then the slope of feed line is - (f - 1)/f (1 - f)/f - 1/f - f/(1 - f) - (f - 1)/f (1 - f)/f - 1/f - f/(1 - f) ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer H₂S is being absorbed in a gas absorber unit. The height of the transfer unit based on the overall mass transfer coefficient on the gas side is 0.4 m. The equilibrium data is given by, y = 1.5 x. The bulk concentration of H₂S has to be reduced from 0.05 to 0.001 mole fraction in the gas side. The height of the tower (in metres) corresponding to an operating line given by, y = 5x + 0.001 is 2 1 1.56 0.56 2 1 1.56 0.56 ANSWER DOWNLOAD EXAMIANS APP
