    摘要: An integrated process for the production of acetic acid, ethylene and vinyl acetate monomer comprising the steps of: (a) evaporating at least part of an ethanol feed stock (b) producing in a first reaction zone a first product stream comprising acetic acid by oxidative or partly oxidative dehydrogenation of ethanol feed stock; (c) producing in a second reaction zone a second product stream comprising ethylene from an ethanol feed stock; (d) reacting in a third reaction zone an acetic acid reaction stream containing at least a portion of the acetic acid from the first reaction zone with an ethylene reaction stream containing at least a portion of the ethylene product from the second reaction zone and with oxygen to a third product stream comprising vinyl acetate monomer; (e) passing at least a portion of the third product stream to a distillation section and isolating at least a portion of the vinyl acetate monomer; (f) supplying at least part of reaction heat from the third reaction zone to provide heat for evaporating at least part of the ethanol feed stock in step (a); (g) supplying at least part of reaction heat from the first reaction zone to provide heat for producing the second product stream in the second reaction zone in step (c) and for distilling of the third product stream in the distillation section in step (e).

    摘要: A process and reactor for the production of acetic acid comprising the steps of: passing a feed stream containing ethanol and water together with a predetermined feed rate of an oxygen containing atmosphere in presence of one or more catalysts being active in simultaneous non-oxidative and oxidative conversion of ethanol to a product stream with acetic acid; recovering from the product stream a stream of acetic acid; optionally recovering reactive derivatives of acetic acid and recycling these to step (a).
