METHOD FOR OBTAINING OLEFINS FROM FURNACE GASES OF STEEL WORKS

The invention relates to a method for processing furnace gas (4) from a steel and/or iron works wherein said furnace gas (4) contains carbon dioxide and/or carbon monoxide and is at least partially integrated into a method (7) for the formation of dimethyl ether in conjunction with a hydrogen contai...

Beschreibung
Zusammenfassung:	The invention relates to a method for processing furnace gas (4) from a steel and/or iron works wherein said furnace gas (4) contains carbon dioxide and/or carbon monoxide and is at least partially integrated into a method (7) for the formation of dimethyl ether in conjunction with a hydrogen containing gas (2) whereby a DME containing product gas (8) is formed. At the outset of the method (7) for forming dimethyl ether a ratio of hydrogen to carbon monoxide weighted with the carbon dioxide concentration (formula (I)) of 0.9 to 1.1 is set and dimethyl ether is formed. The DME containing product gas (8) is integrated into a method (9) for converting dimethyl ether to olefins whereby an olefin containing product gas (10) is formed and wherein olefins (12) in particular ethylene and/or propylene is/are separated from the olefin containing product gas (10) by means of separating methods (11).
