Apparatus and method to remove acid gases from a flue gas containing sulphur dioxide and oxides of nitrogen. The apparatus includes a heat exchanger to reduce incoming flue gas temperatures. An oxidation chamber receives gases from the heat exchanger and oxidises the oxide of sulphur and nitrogen in the flue gases to the highest valency state. A reaction tower receives gases from the oxidizing chamber. The reaction tower includes a reaction surface. There is a first inlet for gas adjacent the base of the reaction tower and a second inlet for a basic compound in the reaction tower, above the first inlet. This arrangement allows counter-current flow of the gas and the basic compound to enable scrubbing of the gas. There is an outlet for scrubbed gases and an outlet for liquids at the tower base.
