Chemical complexes and processes for the oxidative dehydrogenation (ODH) of paraffins to olefins are disclosed. Said chemical complexes comprise a steam cracker, a C2 splitter, and a hydrogenation unit to remove acetylene wherein an oxidative dehydrogenation unit is integrated with the C2 splitter or the hydrogenation unit to remove acetylene. The oxidative dehydrogenation process can be integrated into back end separation processes of a conventional steam cracker to increase capacity and/or to provide a lower energy route to produce olefins, thus reducing costs. Oxidative dehydrogenation processes may be integrated with a number of processes in a chemical plant such as polymerization processes, and the manufacture of glycols, carboxylic acids and esters.
揭示了用于将烷烃氧化脱氢(ODH)制成烯烃的化学复合物和过程。所述化学复合物包括蒸汽裂解炉、C2分馏塔和氢化装置,用于去除乙炔,其中氧化脱氢装置与C2分馏塔或氢化装置集成在一起,以去除乙炔。氧化脱氢过程可以集成到传统蒸汽裂解炉的后端分离过程中,以增加产能和/或提供更低能耗的生产烯烃途径,从而降低成本。氧化脱氢过程可以与化工厂中的许多过程集成,如聚合过程,以及甘醇、羧酸和酯的制造过程。
