Compétences visées

Distillation is the most widely used method and the key operation in any oil refinery. The aim of this course is to present basic tools (equilibrium systems) and theoretical knowledge on distillation. - deal with liquid/vapor equilibrium data - perform heat and mass balance on a distillation unit - determine the number of theoritical plates of a distillation column for a given seperation depending on the reflux ratio - calculate the minimum number of of theoritical plates of a distillation column for a given seperation - calculate a minimum ratio reflux for a given separation.
