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