Model of Energy Transmission-Conversion for Styrene Production |
| |
| Abstract: | This paper deals with the model of energy transmission—conversion for styrene production. The model is formulated on the basis of the concept of energy unit and systems engineering. The expression of exergy efficiency of the system is derived from this model. Thus the main direction of energy saving reformation can be settled according to the contribution coefficient of unit exergy efficiency. The analysis results of this paper accord with those from factory practice. |
