It has been shown that a liquid membrane of aqueous ferrous ethylenediaminetetraacetic acid, maintained between two sets of micro porous, hydrophobic, hollow fibers that are packed in a permeator cell, can selectively and continuously remove sulfur dioxide and nitrogen oxides from the flue gas of power-generating plants, Prepare a detailed drawing of a possible device to carry out such a separation. Show all locations of inlet and outlet streams, the arrangement of the hollow fibers, and a method for handling the membrane liquid. Should the membrane liquid be left in the cell or circulated? Would a sweep fluid be needed to remove the oxides?
