Abstract
The system of propanol-butanol-(3-methyl-l-butanol)- (2-ethyl-l-butanol) in fully thermally coupled distillation column ( FTCD) was discussed, and the modeling and simulation for the energy-saving distillation process were described. The freedom degrees of FTCD and optimal column segments were given. Some operational variables were corresponded with the optimal thermodynamics in FTCD. By means of chemical process simulation software Aspen Plus 11. 1, the results of complex FTCD were analyzed in order to indicate the advanced characteristics of dividing wall column. The energy saving of dividing wall column is 15. 1% and the cost saving of equipment material is 38% compared with the conventional sequence distillation process, which shows a remarkable energy-saving effect. The exergy loss and the thermal target of the total column were imaged by some figures, and the material of dividing wall was proposed to satisfy the thermal recovery in column.关键词
