Abstract
Light olefins may be produced from a hydrocarbon feed by a method that includes separating the hydrocarbon feed into at least a light gas fraction stream comprising C-Calkanes, a light fraction stream comprising Calkanes, and a heavy fraction stream. The temperature cut between the light fraction stream and the heavy fraction stream may be at 280° C. to 320° C. The method may further include steam cracking at least a portion of the light gas fraction stream to produce a steam cracked effluent stream and catalytically cracking at least a portion of the light fraction stream and the heavy fraction stream in a steam enhanced catalytic cracker (SECC) to produce a catalytically cracked effluent stream. The steam cracked effluent stream and the catalytically cracked effluent stream may be sent to a product separator to produce the light olefins.
