  • Abstract Benzene and cyclohexane form an azeotrope (Benzene, 49.7 w.t%, 1 atm), which can be separated by extractive distillation. In this study, o-xylene is added into the sulfolane entrainer for mixed entrainer to make the operation conditions more convenient and controllable. The TAC (total annual cost, generally utilized in global economic optimization) of the process with o-xylene as mixed entrainer is less than that of the process with SULF as entrainer. In addition, as the most energy… CONTINUE READING
