A novel integrated system consisting of a high-temperature heat pump providing 120–130 °C heat and a gas separation unit was developed to recover the industrial waste heat and replace the low-pressure steam used in traditional refinery process. An energy, exergy, economic, and environmental analysis was carried out to evaluate the performance of such integrated system according to the running data of the project. Energy and exergy analyses provide an insight into the quantity and quality of the energy conversion of the integrated system. And the results indicate that the integrated system operates with a high performance and provides significant economic and environmental benefits. |
