The present invention relates to a complex comprising an oxidative dehydrogenation unit. The present invention discloses a chemical complex and method for the oxidative dehydrogenation (ODH) of paraffins to olefins. The chemical complex comprises a steam cracker, a C2 splitter and an acetylene removal hydrogenation unit, wherein the oxidative dehydrogenation unit is integrated with the C2 splitter or the acetylene removal hydrogenation unit. The oxidative dehydrogenation process can be integrated into the back end separation process of a conventional steam cracker to increase production capacity and/or provide a lower energy route to olefin production, thereby reducing costs. The oxidative dehydrogenation process can be integrated with some processes in chemical plants, such as polymerization processes and preparation of diols, carboxylic acids and esters. |
