Mass Transfer In liquid extraction, if the selectivity is unity, then No separation will occur Separation of the constituents is the most effective Amount of solvent required will be minimum Solvent flow rate should be very low No separation will occur Separation of the constituents is the most effective Amount of solvent required will be minimum Solvent flow rate should be very low ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer Compound A is extracted from a solution of A + B into a pure solvent S. A Co-current unit is used for the liquid-liquid extraction. The inlet rate of the solution containing A is 200 moles of B/hr.m² and the solvent flow, rate is 400 moles of S/m². hr. The equilibrium data is represented by Y = 3X² , where Y is in moles of a A/moles of B and X is in moles A/moles of S. The maximum percentage extraction achieved in the unit is 0.9 0.7 0.25 0.5 0.9 0.7 0.25 0.5 ANSWER DOWNLOAD EXAMIANS APP
