In order to save the electric energy and reduce the cost of crude oil consumption and make full use of the waste heat of flue gas and associated gas in a terminal,the latest research progress of domestic and overseas study about waste heat recovery technology are tracked,and the advantages and disadvantages of several waste heat recovery methods are analyzed and compared.Combined with the status of waste heat of flue gas,associated gas and the analysis of energy consumption in a terminal,the low grade waste heat of flue gas and associated gas are recycled by double-effect lithium bromide unit.And the process is simulated by HYSYS software to make thermodynamic calculation meet the summer cooling and winter heating demands of the terminal buildings.The results show that through the application of double-effect lithium bromide unit and improvement of the process,electric energy and crude oil consumption can be saved and reduced remarkably by making full use of the waste heat of flue gas and associated gas.The unit can improve the overall energy utilization efficiency,reduce the thermal pollution and energy waste of the waste heat of flue gas and associated gas,reduce carbon dioxide emissions,and ultimately achieve the purpose of energy saving and emission reduction.
