| Abstract: | The process of Dimethylether (DME) was simulated with Aspen Plus. A new programme of heat match among streams in the process of dimethylether production was put forward. The cool and heat utilities can be saved by 26.04xl0~6kJ/h either after the heat match. DME producing process was optimized according to the result of the heat match. The cool and heat utilities can be saved by 44.82% and 52.14% respectively if the new programme of the heat match is adopted in the DME producing process. |
