Title: METHOD AND PLANT FOR PRODUCING OLEFINS
Abstract:
A method (100, 200) is proposed for producing olefins, wherein a methane-containing first reaction feedstock is subjected to at least one oxidative coupling of methane (2) to give a first product mixture containing methane, higher hydrocarbons and also hydrogen, carbon monoxide and carbon dioxide, and, using at least part of the first product mixture, a first fraction, containing predominantly or exclusively carbon dioxide, and a second fraction, containing predominantly or exclusively methane, hydrogen and carbon monoxide, are formed. Using at least part of the first fraction and at least part of the second fraction, a second reaction feedstock is formed and is subjected to oxygenate synthesis (15) to give a second product mixture containing at least one oxygenate, and, using at least part of the second product mixture, a third reaction feedstock is formed and is subjected to oxygenate-to-olefin conversion (17).
