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 0.7 0.5 0.9 0.25 0.7 0.5 0.9 0.25 ANSWER DOWNLOAD EXAMIANS APP

Mass Transfer An aqueous solution of methanol is to be distilled in a tray column. High pressure steam is available as a source of heat. For a given reflux ratio and overhead composition, two options are being explored; (i) a reboiler is used and (ii) no reboiler is used but steam is fed directly to the bottom of the column. As compared to option (i), in option (ii) More number of trays are required but the residue composition remains unchanged Composition of the residue remains unchanged More number of trays are required and the residue composition is more dilute in methanol Less number of trays are required More number of trays are required but the residue composition remains unchanged Composition of the residue remains unchanged More number of trays are required and the residue composition is more dilute in methanol Less number of trays are required ANSWER DOWNLOAD EXAMIANS APP
