Intensification of heat removal in diabatic columns

Diabatic units having heat exchanger tubes functioning as dephlegmators on trays, which allow to reduce the cost of the process, are considered. It is shown that the most efficient approach is to arrange heat removal with the film flow of the heat carrier in the diabatic column dephlegmator. Heat transfer intensification in a gravitationally flowing film, as well as to in an upward and downward parallel flow during the heating and boiling of the heat carrier was analyzed. Dependences for determining the value of the heat transfer factor are presented.
