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 1 2 1.56 0.56 1 2 1.56 0.56 ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer If a two phase system is in physical equilibrium; then it means that, the Temperature of the liquid phase is equal to that of the vapor phase Total pressure throughout the liquid phase is equal to that throughout the vapor phase Escaping tendency of each component from the liquid phase to the vapor phase is exactly equal to that from vapor phase to liquid phase All of these Temperature of the liquid phase is equal to that of the vapor phase Total pressure throughout the liquid phase is equal to that throughout the vapor phase Escaping tendency of each component from the liquid phase to the vapor phase is exactly equal to that from vapor phase to liquid phase All of these ANSWER DOWNLOAD EXAMIANS APP
