Abstract: The process relates to the use of any naphtha-range stream containing a portion of C8+ aromatics combined with benzene, toluene, and other non-aromatics in the same boiling range to produce toluene. By feeding the A8+ containing stream to a dealkylation/transalkylation/cracking reactor to increase the concentration of toluene in the stream, a more suitable feedstock for the methylation reaction can be produced. This stream can be obtained from a variety of sources, including the pygas stream from a steam cracker, “cat naphtha” from a fluid catalytic cracker, or the heavier portion of reformate.

Abstract: A method and system are disclosed for co-production of olefins and electric power. The method includes determining a separation level, separating a hydrocarbon feed into a light fraction stream and a heavy fraction stream based on the determined separation level; generating electric power from the heavy fraction stream; and cracking the light fraction stream in a pyrolysis unit to produce an effluent comprising olefins. The separation level may be based on olefin production requirements and electric power requirements or specific split of the hydrocarbon feed to be utilized for power generation and olefin production.
