Mass Transfer If a₁ and a₂ are the relative volatilities when the pressure in the distillation column is 1 and 2 atm respectively. Pick out the correct statement. a₁ = a₂ a₁ = 0.5 a₂ a₁ = 2a₂ None of these a₁ = a₂ a₁ = 0.5 a₂ a₁ = 2a₂ None of these ANSWER DOWNLOAD EXAMIANS APP
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 At some point of time, the operation is shifted to total reflux condition (i.e., no product and residue are being withdrawn and feed to the column is stopped).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
