【Abstract】 In order to reduce energy consumption, thermal analysis is applied to a TDA refining process, in which both heat equilibrium and exergy analysis methods have been used. The analysis shows that the exergy analysis method is more instructive than the heat equilibrium analysis. Through exergy analysis, the key subsystems that consume more energy than others are found and improvement is suggested, and the exergy consumption per ton of product may be reduced by 45%. The result of cost analysis shows that the suggested improvement will bring about more economic profit.更多还原
