Abstract

A method for the treatment of a solution of glycol and water e.g. automotive anti-freeze, aircraft de-icing fluid, industrial HVAC coolants and heat transfer fluids, to effect separation of glycol therefrom. The method comprises feeding air into a chamber (2) and spraying a solution of glycol and water into the chamber (2). A solution enriched in glycol is obtained and air is discharged. Steps may be taken to remove contaminants from the solution prior to the teatment.
