Patent abstract

Improved processes and apparatus use a finishing column with a mid-cut that provides alkylbenzene products of high purity containing less than about 1 ppmw benzene and less than about 50 ppmw heavies while accommodating enhancements in the efficiencies and the capacities of the distillation train to recover alkylbenzene from alkylation reaction product and while enabling the use of catalytic treatments to reduce olefinic-component content.
