  • Publication number: 20230399275
    Abstract: A process for producing olefins includes subjecting a first feed stream to dehydrogenation to obtain a first product stream, and subjecting part of the first product stream to a first separation sequence. The first separation sequence comprises a first separation step to which part of the first product stream is fed and in which a gas fraction and a liquid fraction are formed. The first separation sequence comprises a second separation step to which part of the liquid fraction is fed and in which the transfer fraction is formed. A second feed stream is subjected to steam cracking to obtain a second product stream. part of which is subjected to crude gas compression and thereafter to a second separation sequence. In the first separation sequence a transfer fraction is formed. At least part of the transfer fraction is transferred to the steam cracking or the crude gas compression.
