芳烃分离装置物流热能(火用)值计算

A Case of Heat Energy(Exergy) Calculation in Balance in the Aromatics Separation

运用热能(火用)平衡理论于芳烃分离装置各物流热能(火用)值计算。计算结果表明:此芳烃分离装置的热能利用效率(实际)为61.65%、热(火用)利用效率(实际)为59.77%、热力学第一定律效率和热力学第二定律效率分别为23.93%和7.76%。

Using heat energy （exergy） analysis method into aromatics separation unit. The results of energy （exergy） analysis showed that： the heat energy efficiency （actual state） and the heat exergy efficiency （ actual state） of the aromatics separation unit were separately 61.65% and 59.77% , and the first law of thermodynamics efficiency and the second law of thermodynamics were separately 23.93% and 7.76%.
