Optimization of distillation process, based on the real operating data taken from the factory,
was carried out using Aspen Plus simulation engine. The right combination of reflux rate and
product purity was to be found in order to minimize energy consumption in reboiler and
condenser. In order to check the real column flexibility, flooding factor as function of plate
number for different flow rates was studied. Also the effect of overall efficiency of column on
product quality has been studied and the optimum feed tray location was found out based on …

Optimization of distillation process, based on the real operating data taken from the factory,
was carried out using Aspen Plus simulation engine. A need for the optimization came from
the fact that the feed stream quality had been significantly changed recently, together with
some of the process parameters. The right combination of pressure and reflux rate was to be
found in order to minimize the energy consumption in the reboiler and to obtain the required
product purity. The real column efficiency was found and the possibility of column capacity …
