提出包含冷凝器和再沸器的扩展总复合曲线 ,把冷凝器和再沸器按热负荷和温位折算成相应的冷热物流 ,运用夹点分析技术使之与过程系统进行热集成 ,并把该技术用于某厂环己酮精馏系统的扩产改造。实践表明 ,能耗节约31 %。
An extended total composite curve including a condenser and a reboiler is proposed. The condenser and the reboiler are converted into corresponding hot and cold streams according to the heat load and the temperature, and the heatsink is integrated with the process system using pinch analysis The technology for a plant cyclohexanone distillation system expansion transformation. Practice shows that energy consumption savings of 31%.
