Mass Transfer In liquid extraction, if the selectivity is unity, then Solvent flow rate should be very low Separation of the constituents is the most effective No separation will occur Amount of solvent required will be minimum Solvent flow rate should be very low Separation of the constituents is the most effective No separation will occur Amount of solvent required will be minimum ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer In case of steam distillation, the steam leaving the liquid is not completely saturated with distillate vapour, because Saturated steam is used for steam distillation Mixing of steam with the material being vaporised is not so intimate as to result in equilibrium condition Total pressure is less Temperature is less Saturated steam is used for steam distillation Mixing of steam with the material being vaporised is not so intimate as to result in equilibrium condition Total pressure is less Temperature is less ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Cox chart, which is useful in the design of distillation column particularly for petroleum hydrocarbons, is a plot of (where, P = vapor pressure, T = temperature) P vs . log T T vs .
