A multicomponent distillation column for propylene purification was optimized in order to increase its energetic effectively. The ©-method coupled with the Soave-Redlich-Kwong equation of state for generating K-values and enthalpies was used. The optimal combination of pressure, temperature and reflux flow provided the decrease of steam consumption and loss of propylene with bottom flow
