Abstract
The method and system of the present invention is designed to minimize exergy consumption consistent with a given level of product purity. For example, in a distillation system, the design employs a plurality of thermostatted trays which are maintained at a sequence of temperatures specified by finding the optimal control for an irreversible thermodynamic process. The specified temperatures at each tray are achieved with the help of a tandem heat pump which works over the range of required temperatures and which delivers the specified heat demands.
Claims6
A method of minimizing exergy consumption in a distillation system comprising the step of thermostatically maintaining substantially equal thermodynamic distances between each tray in the system by controlling heat delivered to or extracted from each tray.
A method of minimizing exergy consumption in a distillation system comprising the step of thermostatically maintaining substantially equal thermodynamic distances between each tray in the system by controlling pressure at each tray.
A method of minimizing exergy consumption in a distillation system comprising the step of thermostatically maintaining substantially equal thermodynamic distances between each tray in the system by controlling concentration of a chemical component at each tray.
