Integrated exhaust gas cooling system and corresponding method

摘要

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.
