Abstract

The stripping of volatile organic compounds plays an important role in ground water remediation and modern packings give increased column performance. An experimental comparison is made of the performance of two modern random dumped packings, Rauschert Hi-flow and Lantec Lanpac in stripping ethanol or acetone from aqueous solution by counter current flow. The studies were carried out in a 1.5 ft diameter column packed to a depth of 9.5 ft with the gas flow varying from 500 Ib./hr.fP to 2450 Ib./hr.fP and the liquid flow from 1950 Ib./hr.fP to 4500 Ib./hr.fP. Temperature was varied from 13 °C to 36 °C. The gas flow rate was measured using an anemometer and the liquid flow with a
