The pure linear alkylbenzenes (LAB) are widely used in detergent manufacture, which are generally obtained by alkylation of benzene with linear C 9 ‐C 13 olefins How to decrease the loss of LAB during the distillation process is always the focus of manufacturers' attention In this paper, a mathematic model of a newly rebuilt LAB distillation process is established and some operation and control problems are studied by simulation and analysis we not only find the bottleneck and the optimal operating conditions of the distillation process, but also locate the new sensitive plates with optimal ranges of temperature The simulation results indicate that the loss of LAB can be reduced from 1.0% to 0.05%, simultaneously with the distillate of regular LAB product (>99.5% mass fraction) increases of 600 kg/h under the optimal operating conditions
