Mass Transfer Plate towers are preferred to packed towers, when large temperature changes are involved, because of the reason that the Pressure drop in the equipment will be very high Packing may be crushed due to thermal expansion/contraction of the components of the equipments None of these Viscosity variation of the fluids may cause channeling/flooding Pressure drop in the equipment will be very high Packing may be crushed due to thermal expansion/contraction of the components of the equipments None of these Viscosity variation of the fluids may cause channeling/flooding ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Solvent extraction is the terminology applied to the liquid-liquid extraction, which is preferred for the separation of the components of liquids, when Viscosity of liquid components is very high One of the liquid components is heat sensitive One of the liquid components has very high affinity towards the solvent Extracting solvent is cheaply & abundantly available Viscosity of liquid components is very high One of the liquid components is heat sensitive One of the liquid components has very high affinity towards the solvent Extracting solvent is cheaply & abundantly available ANSWER DOWNLOAD EXAMIANS APP
