| Abstract: | High energy consume for recovery of DMF by convention distalliation, a multi-effect heat pump distillation for recovery DMF was proposed. Base on the energy equilibrium model of multi-effect heat pump distillation,optimization simulations for the proposed technologies were performed by ASPEN PLUS software which RADFRAC blocks and UNIQUAC physical property were used,and the optimum operation conditions were determined. Base on the results, cost-effectiveness analysis were performed for the proposed technologies, the best recovery technology was confirmed in response to the objective function of the net economy benefit. |
