Abstract (en)
[origin: WO9521682A1] A method for the treatment of a gaseous acidic substance which includes delivering the said substance to a packed tower (3) or scrubber in which the gaseous acidic substance is intimately contacted with a supply of a dilute aqueous extractant solution, the tower being in an extractant solution recirculation loop in which extractant solution is delivered to the tower and is removed from the tower and the concentration of acid in solution in the loop is maintained in an acid concentration range by addition of dilute aqueous solution to the loop and the extraction of aqueous solution of greater acidic concentration from the loop.
