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 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 ANSWER DOWNLOAD EXAMIANS APP
