<p>A distillation system includes a distillation column (10) having a plurality of thermostatted trays (11), each of the trays (11), having a cylindrical vessel (12) wrapped with heat exchange coils (13), are maintained at a sequence of temperatures specified by finding the optimal control for an irreversible process. The specified temperatures at each tray are achieved with the help of a tandem heat pump which works over the range of required temperaturres and which delivers the specific heat demands.</p> |
