Mass Transfer In a single stage extraction process, 10 kg of pure solvent S (containing no solute A) is mixed with 30 kg of feed F containing A at a mass fraction xf = 0.2. The mixture splits into an extract phase E and a raf-finate phase R containing A at xB = 0.5 and xR = 0.05 respectively. The total mass of the extract phase is (in Kg) 8.89 8.25 6.89 10 8.89 8.25 6.89 10 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) Less number of trays are required More number of trays are required and the residue composition is more dilute in methanol Composition of the residue remains unchanged More number of trays are required but the residue composition remains unchanged Less number of trays are required More number of trays are required and the residue composition is more dilute in methanol Composition of the residue remains unchanged More number of trays are required but the residue composition remains unchanged ANSWER DOWNLOAD EXAMIANS APP
