A New Method for Energy-Saving Tray Design

With the enhancement of people's awareness of protecting our resources and environment, it becomes an urgent subject to make effective use of resources and to reduce process energy consumption. Distillation, a major energy-consumption unit operation in chemical process, has been analyzed intensively in terms of entropy generation rate. By using various kinds of thermodynamic analysis methods, chemical engineers have gained many valuable results. These researches, however, merely focused on different technological processes and various process conditions. The effect of tray structural parameter on process entropy generation has largely been neglected.
