| titleOfInvention | Method for producing 1,3-butadiene by dehydrogenating n-butenes from the c4 fraction of a steam cracker |
| abstract | The method has the steps of A) providing a feed gas flow a, which contains butanes, 1,3-butadiene, n-butenes, and isobutane, from a steam cracker; B) separating the feed gas flow a by means of an extractive distillation process using a solvent, which is selective for 1,3-butadiene, into a material flow b1, which contains 1,3-butadiene and the selective solvent, and a material flow b2, which contains butanes, n-butenes, and isobutane; C) separating isobutane from the material flow b2, a material flow c being obtained which contains butanes and n-butenes; D) feeding the n-butene-containing material flow c, optionally an oxygen-containing gas, and optionally steam into at least one dehydrogenation zone and dehydrogenating n-butenes into 1,3-butadiene, a product gas flow d being obtained which contains 1,3 butadiene, non-converted n-butenes, butanes, steam, low-boiling point hydrocarbons, high-boiling point auxiliary components, optionally oxygen, optionally carbon oxides, and optionally inert gases; E) cooling and compressing the product gas flow d, at least one aqueous condensate flow e1 and a gas flow e2, which contains 1,3-butadiene, n-butenes, butanes, steam, optionally oxygen, low-boiling point hydrocarbons, optionally carbon oxides, and optionally inert gases, being obtained; Fa) separating non-condensable and low-boiling point gas components, which comprise optionally oxygen, low-boiling point hydrocarbons, optionally carbon oxides, and optionally inert gases, as gas flow f2 from the gas flow e2 by absorbing the C 4 -hydrocarbons, which comprise 1,3-butadiene and n-butenes, in an absorption agent, wherein an absorption agent flow, which is loaded with C 4 -hydrocarbons, and the gas flow f2 are obtained, and Fb) subsequently desorbing the C 4 -hydrocarbons from the loaded absorption agent flow, a C 4 -hydrocarbon flow f1 being obtained; G) separating the C 4 -hydrocarbon flow f1 by means of an extractive distillation process using a solvent, which is selective for 1,3-butadiene, into a material flow g1, which contains 1,3-butadiene and the selective solvent, and a material flow g2, which contains butanes and n-butenes. |
