| Abstract: | The performances of Raschig rings, Pall rings, Intalox saddles, and Berl saddles were compared in respect to pressure drop and mass transfer efficiency, in a 6-in. I. D. tower having a packed height of 4-ft., over a matrix of gas and liquid flowrates representing the irrigating and loading flow regimes. The mass transfer experiments were conducted employing a gas absorption system in which both phase films control the overall rate of mass transfer, an improvement in terms of industrial applicability over many previous studies. The Berl saddles were observed to yield the lowest pressure drops of the four. The Intalox saddles yielded the highest overall mass transfer coefficients, followed closely by the Berl saddles and Raschig rings. |
