ABSORPTION OF NO AND SO₂ IN FE(II)-EDTA SOLUTIONS II. PACKED COLUMN SIMULATION

Abstract

Two methods were applied in simulating the height of a packed column required for the removal of NO and SO₂ by absorption into Fe(II)-EDTA solutions. The first method used a double-stirred cell to simulate a packed column by matching the gas- and liquid-phase mass transfer coefficients of the two device. The second method used the differential mass balance including reaction kinetics. Data taken in an 8 cm diameter, 40 cm packed height column and in a double-stirred cell were employed in illustrating the methodology. The two methods of prediction were quite satisfactory.
