| 摘要 |
<p>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).</p> |
