    摘要: Processing schemes and arrangements are provided for obtaining propylene and propane via the catalytic cracking of a heavy hydrocarbon feedstock and converting the propylene into cumene without separating the propane from the propane/propylene feed stream. The disclosed processing schemes and arrangements advantageously eliminate any separation of propylene from propane produced by a FCC process prior to using the combined propane/propane stream as a feed for a cumene alkylation process. A bottoms stream from the cumene column of the cumene alkylation process can be used and an absorption solvent in the FCC process thereby eliminating the need for a transalkylation reactor and a DIPB/TIPB column.

    摘要: 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.

    摘要: A sprayable wash-and-wax composition which includes biodegradable surfactants and water repelling sealants. The sprayable composition preferably is packaged in an aerosol can and is dispensed as a foamed composition onto the car surface to be cleaned. The foamed composition is thereafter wiped from the car surface to produce a cleaned surface which is then buffed to a high gloss.

    摘要: This ethylbenzene process involves contacting, in an alkylation zone, a first benzene recycle stream and an ethylene feed stream with an alkylation catalyst to form ethylbenzene. In a transalkylation zone, a polyethylbenzene recycle stream and a second benzene recycle stream are contacted with a transalkylation catalyst to form additional ethylbenzene. The effluents are passed into a benzene distillation column. From the benzene distillation column, a first benzene recycle stream is removed as overhead; a second benzene recycle stream is removed as a side draw; and a bottoms stream comprising polyethylbenzene, ethylbenzene, and flux oil is removed from an end. The bottoms stream is passed to a dividing wall distillation column where the polyethylbenzene recycle stream is removed from an intermediate point; an ethylbenzene product stream is removed from a first end, and a heavy oil stream is removed from a second end.
