Abstract:
Oxidative dehydrogenation is an alternative to the energy extensive steam cracking process presently used for the production of olefins from paraffins, but has not been implemented commercially partially due to the unstable nature of hydrocarbon/oxygen mixtures, and partially due to the cost involved in the construction of new facilities. An oxidative dehydrogenation chemical complex designed to reduce costs by including integration of an oxygen separation module that also addresses safety concerns and reduces emission of greenhouse gases is described.

Claim (Index 14):
A process for the oxidative dehydrogenation of a lower alkane into a corresponding alkene, the process comprising:\n i) contacting, in at least one oxidative dehydrogenation reactor, optionally in the presence of an inert diluent, an oxygen containing gas and a lower alkane containing gas, with an oxidative dehydrogenation catalyst to produce a product stream comprising said corresponding alkene, and possibly one or more of:\n a. unreacted lower alkane; \n b. oxygen; \n c. inert diluent; \n d. carbon oxides, including carbon dioxide and carbon monoxide; \n e. oxygenates, including but not limited to, one or more of acetic acid, acrylic acid and maleic acid; and \n f. water; \n ii) passing said product stream from i) through a quench tower to remove oxygenates and water from said product stream; iii) passing said product stream from ii) through an amine wash to remove carbon dioxide from said product stream; iv) passing said product stream from iii) through a dryer to remove water; v) passing said product stream from iv) through a distillation tower to separate an overhead stream comprising C1 hydrocarbons and any other compounds lighter than C2/C2+ hydrocarbons; vi) passing said overhead stream from v) and optionally a combustible fuel into one or both of a retentate side and a permeate side of an oxygen separation module comprising an oxygen transport membrane; vii) introducing atmospheric air into said retentate side allowing for generation of heat by combustion of said overhead stream and said optional fuel within said retentate side to increase the temperature of said oxygen transport membrane to at least 850\u00b0 C. permitting unreacted oxygen from said atmospheric air to cross said oxygen transport membrane into said permeate side producing an oxygen enriched gas on said permeate side and leaving an oxygen depleted air containing combustion products on said retentate side; viii) expelling said oxygen depleted air from said retentate side through an exhaust on said oxygen separation module; and x) removing said oxygen enriched gas through an oxygen rich outlet on said oxygen separation module; optionally, said oxygen enriched gas is directed back to i) as, or a portion of, said oxygen containing gas introduced into said oxidative dehydrogenation reactor.
