| titleOfInvention | Method for producing 1,3-butadiene from n-butenes by oxidative dehydrogenation |
| abstract | The present invention relates to a process for the preparation of a feed gaseous feedstock (a) comprising A) a feed gaseous feedstock comprising n-butene; B) feeding a feed gaseous feedstock (a) containing n-butene and an oxygen-containing gas to at least one oxidative dehydrogenation zone and oxidizing dehydrogenating n-butene to form butadiene to form butadiene, unreacted n- Obtaining a product gas oil b) containing butene, water vapor, oxygen, low boiling hydrocarbons, secondary components boiling at high temperatures, optionally carbon oxides and optionally inert gases; Ca) product gas by contacting an animal (b) with an organic solvent as a coolant; Cb) product gas oil The animal (b) is compressed in one or more compression stages to remove at least one aqueous condensate oil (c1) and the butadiene, n-butene, water vapor, oxygen, low boiling hydrocarbons, optionally carbon oxides and optionally inert gases (C2) which contains the gaseous oily animal (c2); D) absorbing C4-hydrocarbons containing butadiene and n-butene into the absorption means to obtain C4-hydrocarbon-loaded sorbent feedstocks and gaseous feedstuffs (d2), thereby producing oxygen, a low boiling hydrocarbon, The portion of the non-condensable low boiling point gas component containing the inert gas is separated from the gas oil animal (c2) as the gas oil animal (d2), and subsequently, the C4 hydrocarbon is desorbed from the charged sorbent oil animal to produce the C4- (d1); E) By means of an extractive distillation using a solvent selective for butadiene, the C4-product milk animal (d1) was added to a material milk (e1) containing butadiene and a selective solvent and a material milk (e1) containing n-butene e2); F) distillation of material milk (e1) containing butadiene and optional solvent to obtain material milk (f2) comprising material milk animal (f1) and butadiene consisting essentially of a selective solvent, n ≪ RTI ID = 0.0 > butadiene < / RTI > |
