| Abstract: | Energy saving in refineries needs to be carried out based on the scientifically energy analysis and evaluation of the processing units.The atmospheric and vacuum distillation unit in a refinery was taken as an example,its energy and exergy balances were then worked out through calculation according to the three link method for process integration following the First Law and the Second Law of thermodynamics.The results were analyzed,and the corresponding measures for energy saving were proposed. |

| Keywords: | atmospheric and vacuum distillation unit energy saving three link energy method energy and exergy balance analysis |
