| abstract |
The present invention provides a process for producing olefins, comprising:n a. cracking an ethane-comprising feed in a cracking zone under cracking conditions to obtain at least olefins and hydrogen; b. converting an oxygenate feedstock in an oxygenate-to-olefin zone to obtain at least olefins; wherein at least part of the oxygenate feedstock is obtained by providing hydrogen obtained in step a) and a feed containing carbon monoxide and/or carbon dioxide to an oxygenate synthesis zone and synthesizing oxygenates. nn In another aspect the invention provides an integrated system for producing olefins. |
