Mass Transfer A distillation column with N plates is being operated under normal conditions. At some point of time, the operation is shifted to total reflux condition (i.e., no product and residue are being withdrawn and feed to the column is stopped). At the new steady state, The top and bottom compositions are unchanged with and without total reflux The top and bottom compositions correspond to the maximum enrichment available Composition of vapors and that of liquid do not vary throughout the column Reboiler load and condenser load are minimum The top and bottom compositions are unchanged with and without total reflux The top and bottom compositions correspond to the maximum enrichment available Composition of vapors and that of liquid do not vary throughout the column Reboiler load and condenser load are minimum ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Steam distillation is not recommended to be used, if the 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 Material to be distilled is thermally unstable or has the tendency to react with other components associated with it, at the boiling temperature Liquids decompose, if distilled directly at atmospheric pressure 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 Material to be distilled is thermally unstable or has the tendency to react with other components associated with it, at the boiling temperature Liquids decompose, if distilled directly at atmospheric pressure ANSWER DOWNLOAD EXAMIANS APP
