This study developed an innovative configuration for cumene production process from an energy efficiency point of view by investigating the feasibility of self-heat recuperation technology to the process using a reactive top dividing wall column. The optimization was done for the structure of the reactive top dividing wall column so that lower energy requirement could be obtained. Later on heat-integrated arrangement was proposed and a side-reboiler was placed on the reactive distillation column part. The innovative configuration provided preferable conditions for the self-heat recuperation by avoiding the remixing effect and reducing the energy requirement. The result showed that the innovative configuration could save up 30% of the overall energy requirement, compared to the conventional sequence.
