The performance of a new high intensity contactor in stripping dissolved aromatics from water is compared experimentally with that of a packed column. Interest in this application comes from the offshore oil and gas industry where the very large flows of produced water discharged to sea contain environmentally harmful aromatics. Processing intensity in the new contactor can be over two orders of magnitude higher than in a column due to the high liquid fluxes and lower equivalent HTU values. HTU values decrease with gas rate, G, according to HTU a G-n where n here is 0.53. Ancillary measurements of bubble size distributions and preliminary theoretical analysis show that the improved performance with salt water can be attributed to the decrease in bubble size caused by suppression of bubble coalescence.
