Mass Transfer For gas absorption, low viscosity solvents are preferred, because of their Better flow characteristics Low pumping pressure drop All of these Rapid absorption rates Better flow characteristics Low pumping pressure drop All of these Rapid absorption rates ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Steam distillation is not recommended to be used, if the Material to be distilled is thermally unstable or has the tendency to react with other components associated with it, at the boiling temperature Azeotropic mixture is to be separated and the final product is miscible with water Material can not be distilled by indirect heating even under low pressure, because of the high boiling temperature Liquids decompose, if distilled directly at atmospheric pressure Material to be distilled is thermally unstable or has the tendency to react with other components associated with it, at the boiling temperature Azeotropic mixture is to be separated and the final product is miscible with water Material can not be distilled by indirect heating even under low pressure, because of the high boiling temperature Liquids decompose, if distilled directly at atmospheric pressure ANSWER DOWNLOAD EXAMIANS APP
