Abstract:
1. A combined xylene isomerization and transalkylation process comprising: isomerizing a feed stream in an isomerization reactor under isomerization conditions to produce an isomerization product; transalkylating a feed stream in a transalkylation reactor under transalkylating conditions to produce a transalkylation product; providing a split separator having a baffle separating the separator into two sides, the separator having an isomerization inlet on the isomerization side of the baffle and a transalkylation inlet on the transalkylation side of the baffle, the baffle extending from a bottom of the separator to a location above a highest inlet; introducing the isomerization product into the isomerization side of the separator through the isomerization inlet; introducing the transalkylation product into the transalkylation side of the separator through the transalkylation inlet; separating the isomerization product in the isomerization side of the separator to produce a separator isomerization bottoms stream; separating the transalkylation product in the transalkylation side of the separator to produce a separator transalkylation bottoms stream; and fractionating the separator isomerization bottoms stream and the separator transalkylation bottoms stream in a fractionation column to produce a fractionation column bottoms stream.
