| Abstract: | The energy saving more and more attention has been paid, pinch technology is the most widely used thermal integration technologies. In the paper, pinch technology synthesis of dimethyl carbonate was used to analyze the system, identified with the energy situation is not quite reasonable between. The synthesis and distillation of dimethyl carbonate as a system of four modules in their entirety, presented dimethyl carbonate synthesis and distillation unit of the heat exchanger network optimization. Optimized the low pressure steam system can save 33.7 %, 93.6 %cooling water conservation. |
