An improved, integrated exhaust gas cooling system and method. The system includes an expansion joint linking the integrated exhaust gas cooling system to an upstream source of exhaust gas and a pre-oxidation section through which exhaust gas travels. A hot temperature zone in which the exhaust gas is maintained at a temperature in a temperature range that is optimal for an oxidation process extends through the pre-oxidation section. The system further includes an oxidation catalyst, in the hot temperature zone extending from the pre-oxidation section and downstream from the pre-oxidation section. The exhaust gas passes through the oxidation catalyst. The system includes a post-oxidation section downstream of the oxidation catalyst and through which the oxidized exhaust gas passes.
