Abstract
The NFM (N-formylmorpholine) extractive distillation process is used for the purpose of recovering aromatics, such as benzene, toluene, and xylene. The thermodynamic equation used in the simulation is the NRTL equation, and NRTL interaction binary parameters were obtained by experimental data. The missing thermodynamic properties are predicted by group contribution method. Simulation results of the extractive distillation column were in good agreement with the operation data.
