Mass Transfer In a moderately sized packed absorption tower, channeling (which is most severe with stacked packings) can be minimised by taking the ratio of tower diameter to packing diameter > 4 :1 < 6:1 < 8 : 1 > 8:1 > 4 :1 < 6:1 < 8 : 1 > 8:1 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 0.56 1.56 1 2 0.56 1.56 1 2 ANSWER DOWNLOAD EXAMIANS APP
