Abstract:
1. An integrated system for catalytically cracking a hydrocarbon feedstock, obtaining selected hydrocarbon fractions including a combined propane/propylene stream and reacting the propylene of the combined propane/propylene stream with benzene to produce a cumene product stream, the integrated system comprising: a fluidized reactor zone wherein the hydrocarbon feedstock contacts a catalyst to produce an effluent stream including propane and propylene, a separation zone for separating the effluent stream into at least one separator liquid stream comprising propane and propylene and a separator vapor stream; at least one treatment zone to remove impurities from the separator liquid stream to provide a combined propane/propylene stream; a process line feeding the combined propane/propylene stream to an alkylation reactor of an alkylation zone for reacting at least some of the propylene in the combined propane/propylene stream with benzene to form cumene; a stripper for stripping C at least one heat exchanger for transferring heat from the alkylation reactor to the stripper.
