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 At some point of time, the operation is shifted to total reflux condition (i.e., no product and residue are being withdrawn and feed to the column is stopped).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, Reboiler load and condenser load are minimum Composition of vapors and that of liquid do not vary throughout the column The top and bottom compositions correspond to the maximum enrichment available The top and bottom compositions are unchanged with and without total reflux Reboiler load and condenser load are minimum Composition of vapors and that of liquid do not vary throughout the column The top and bottom compositions correspond to the maximum enrichment available The top and bottom compositions are unchanged with and without total reflux ANSWER DOWNLOAD EXAMIANS APP
