    摘要： A method (100) for producing olefins is proposed, wherein a first gas mixture (b) is produced by means of a steam cracking process (1) and a second gas mixture (s) is produced by means of an oxygenate-to-olefin process (2), the first gas mixture (b) and the second gas mixture (s) each containing at least hydrocarbons with one to four carbon atoms. It is proposed that from the first gas mixture (b) a first fraction (h) is formed which contains at least the great majority of the hydrocarbons with four carbon atoms previously contained in the first gas mixture (b), from the second gas mixture (s) a second fraction (y) is formed which contains at least the great majority of the hydrocarbons with four carbon atoms previously contained in the second gas mixture (s), and that the hydrocarbons contained in the second fraction (y) and previously in the second gas mixture (s) are predominantly subjected in the steam cracking process (1) to cracking conditions under which any n-butane present is reacted by less than 92%. The invention further relates to an apparatus for this purpose.

    摘要： A method (100) for obtaining olefins is proposed, wherein a first gas mixture (b), which is produced by a steam cracking process (1), is at least partially used to form a first separation feedstock (f) which contains hydrocarbons with one to five carbon atoms, and from which at least a first separation product (g) and a second separation product (h, o) are produced, the first separation product (g) containing at least the greater proportion of the hydrocarbons with one carbon atom and of the hydrocarbons with two carbon atoms contained in the first separation feedstock (f), and the second separation product (h, o) containing at least the greater proportion of the hydrocarbons with four carbon atoms and of the hydrocarbons with five carbon atoms contained in the first separation feedstock (f), and wherein a second gas mixture (r) which is produced by an oxygenate-to-olefin process (2) is used at least partially to form a second separation feedstock (t) which contains hydrocarbons with one to five carbon atoms, and from which at least a third separation product (e, y) and a fourth separation product (l, z) are produced, the third separation product (e, y) containing at least the greater proportion of the hydrocarbons with one carbon atom and of the hydrocarbons with two carbon atoms contained in the second separation feedstock (t), and the fourth separation product (l, z) containing at least the greater proportion of the hydrocarbons with four or five carbon atoms contained in the second separation feedstock (t). The third separation product (e, y) is also at least partially used to form the first separation feedstock (f), and a third separation feedstock (h, l) (o, z) is formed from at least part of the fourth separation product (l, z) and of the second separation product (h, o) and is subjected to a separation (14).
