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 > 8:1 < 8 : 1 < 6:1 > 4 :1 > 8:1 < 8 : 1 < 6:1 > 4 :1 ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Though, theoretically the adsorption & desorption isotherms is expected to coincide but sometimes at least a part of the isotherms does not coincide and this phenomenon is known as adsorption hysterisis. In such cases, the desorption equilibrium pressure is __________ that obtained for adsorption. Same as Either same or higher than Lower than Higher than Same as Either same or higher than Lower than Higher than ANSWER DOWNLOAD EXAMIANS APP
