Document Type and Number:

WIPO Patent Application WO/2009/108280

Kind Code:

A3

Abstract:

Systems and processes for producing one or more olefins. A feed containing 90% by weight or more C4 and higher hydrocarbons can be cracked at conditions sufficient to provide an olefinic mixture and an aromatic mixture. The olefinic mixture can comprise 90% by weight or more Ci to C3 hydrocarbons. The aromatic mixture can comprise 90% by weight or more C4 and higher hydrocarbons and one or more aromatics. The aromatic mixture can be contacted with one or more solvents to selectively separate at least a portion of the one or more aromatics therefrom to provide an aromatic-rich mixture and an aromatic-lean mixture. At least a portion of the aromatic-lean mixture can be recycled to the feed prior to cracking.
