Abstract
Processing schemes and arrangements for application of a dividing wall separation column in the processing of an effluent resulting from FCC processing modified for increased light olefin production. The dividing wall separation column desirably splits a naphtha feedstock produced or resulting from such modified FCC processing to produce or form a light fraction containing C5-C6 compounds, an intermediate fraction containing C7-C8 compounds and a heavy fraction containing C9+ compounds.
