Analysis of heat cost for rectification was performed taking into account the phase state of the original mixture. It was proved theoretically that increasing feed vapor fraction leads to decreasing energy consumption in conventional distillation process. With a low excess factor of reflux. total energy consumption by the reboiler and feed heater is greater than for a distillation col... https://lecoureures.shop/product-category/course-a-pied-femme-vetements-manteau-nylon/
