| 摘 要： | 二氧化碳的分离与纯化是当前的研究热点，而随着环保要求的提高，传统单一的分离手段难以满足行业要求，多种分离方法的集成逐渐得到研究者的重视。以整体煤气化联合循环发电系统（IGCC）流程中二氧化碳的分离与回收环节为例，在流程模拟的基础上，拟合出该体系状态方程的多项式形式。进一步，构建耦合膜-闪蒸超结构数学模型，在设定最低产物纯度和回收率的情况下，以最小化年度费用为目标，筛选出最优的分离序列。

| Abstract: | Separation and purification of carbon dioxide is current research hotspot. With increasing needs for environmental protection, traditional single separation techniques are difficult to meet these discharge specifications. Integration of multiple separation methods has gradually gained research attention. Separation and recovery of carbon dioxide in the integrated gasification combined cycle (IGCC) process was studied by process simulation and polynomial state equations were obtained for such system. Furthermore, a mathematical superstructure model of hybrid membrane-cryogenic flash distillation was established. Optimal separation sequence was found by targeting minimal annual cost at pre-set lower specification of product purity and recovery. The optimized process show excellent separating performance of membrane after flash configuration and multistage membrane structure. Compared to control process, optimized process not only guarantees product recovery and purity but also decreases total annual cost by almost 27%. |
