摘要： This cumene process involves contacting, in an alkylation zone, a first benzene recycle stream and a propylene feed stream with an alkylation catalyst to form cumene. In a transalkylation zone, a polyisopropyl benzene recycle stream and a second benzene recycle stream are contacted with a transalkylation catalyst to form additional cumene. The effluents are passed into a dividing wall distillation column. A cumene stream is removed from an intermediate point of the dividing wall fractionation column; a first benzene recycle stream is removed from a first end and a heavy aromatics stream is removed from a second end. A second benzene recycle stream is removed from an intermediate point located between the first end and the cumene stream. A polyisopropyl benzene stream is removed from an intermediate point of located between the second end and the cumene stream.

摘要： In processes for recovering one or more xylene isomers and isomerizing the remaining isomers for recycle, the isomerate is distilled to provide a toluene-containing overhead, a mid-boiling fraction containing C8 aromatics and a bottoms fraction containing C8 aromatics and C9+ aromatics. The mid-boiling fraction is recycled to the unit for recovering the sought xylene isomers and has sufficiently low content of C9+ aromatics that the separation feed to the unit for recovering the sought xylene isomers contains up to about 500 ppm-mass C9+ aromatics. The processes provide a high quality xylene isomer product while achieving at least one of debottlenecking, energy savings and capital savings.

摘要： A control apparatus and control method for controlling the separation in a dividing wall distillation column of at least two feeds into at least three products is disclosed. The apparatus uses a temperature measuring device to measure the temperature of fluid in the column, a controller, and a means for adjusting the temperature of fluid in the column. The temperature measuring device may be on either side of the dividing wall or above or below the dividing wall, and more than one such device may be used. The apparatus and method may be used in the production of alkylaromatic hydrocarbons by alkylating aromatic hydrocarbons with olefinic hydrocarbons.

摘要： A process to increase the octane number of a naphtha boiling range feed stock has been developed. Using a dividing wall column, the feed stock is separated into a light fraction comprising compounds containing five carbon atoms or less, an intermediate fraction containing largely compounds having six carbon atoms, and a heavy fraction which comprises compounds containing more than six carbon atoms. The light and heavy fractions are passes to a gasoline blending pool. The intermediate fraction is isomerized to increase the octane number of the intermediate fraction and form an isomerate. The isomerate is passed to the gasoline bending pool.

摘要： Savings in the processing of a naphtha boiling range feed containing a thiophene are achieved by fractionating the feed stream in a single dividing wall column to yield a C6-minus overhead stream, a side-draw containing the majority of the C6 and C7 paraffins and olefins, and a bottoms stream comprising C7 and heavier hydrocarbons. A dividing wall column provides better control of the concentration of both thiophene and toluene in the side-draw. Less of the valuable naphtha is lost and the amount of thiophene in the overhead product is minimized.
