| Abstract: | The entransy principle and dissipation extremum have opened a new direction for energy saving in chemical process systems. Recent development of entransy theory was briefly discussed on definition, physical meaning and finding as a process parameter. Application of entransy theory in energy saving of chemical processes was summarized from several aspects, such as heat exchanger design, irreversibility of thermodynamics process and heat exchanger network synthesis. Scientific characteristics of entransy theory were explored through comparison of entropy generation rate and entransy dissipation rate as well as combination of entransy dissipation extremum principle to heat exchanger network synthesis. |
