Mass Transfer Fenske's equation for determining the minimum number of theoretical stages in distillation column holds good, when the Multicomponent distillation is involved Mixture (to be separated) shows negative deviation from ideality Mixture (to be separated) shows positive deviation from ideality Relative volatility is reasonably constant Multicomponent distillation is involved Mixture (to be separated) shows negative deviation from ideality Mixture (to be separated) shows positive deviation from ideality Relative volatility is reasonably constant ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer In distillation column design, the McCabe-Thiele procedure is inadequate and a Ponchan-Savarit procedure is needed, when The latent heat of vaporisation of the more and less volatile components are greatly different An azeotrope forms A total condenser is used Saturated feed is not used The latent heat of vaporisation of the more and less volatile components are greatly different An azeotrope forms A total condenser is used Saturated feed is not used ANSWER DOWNLOAD EXAMIANS APP
