| 摘 要： | 放热反应的反应-分离系统,可通过工艺设计实现能量集成的效果,改变其工艺条件,调整系统能量利用需求。本文提出反应-分离系统逐步优化的能量集成策略,以连续反应合成乙二醇丁醚醋酸酯的生产工艺为例,利用Aspen Plus软件对其进行模拟计算,采用过程模拟技术与夹点技术相结合的办法,以温焓图(T-H图)上冷、热物流之间的匹配关系为尺度,以尽可能减少公用工程能耗为目标,通过调整分离塔塔压实现能量集成。计算结果表明,优化后系统额外添加的冷、热公用工程能耗由原来的185.8 kW降至105.8 kW,仅为优化前的56.9%,全系统能量的利用效率提高,达到系统精馏塔与换热网络能量集成的目的。本文的研究利用模拟软件科学计算与系统整体匹配相结合的方法,对过程工业企业的能量集成有着很大的推广潜力和应用价值。
