有效回收挥发性有机物（VOCs）不仅可以防止大气污染，还可以获得潜在的经济效益。然而，传统的VOCs回收技术面临着能耗高、回收率低的挑战。本文分别采用分子模拟和过程模拟对膜材料和膜-低温组合工艺进行了优化设计。通过分子模拟，预测了152种MOFs/PDMS和MOFs/PTMSP混合膜。结果表明，PCN-48/PDMS和ZIF-12/PTMSP混合膜的选择性分别为56.6和31.9，渗透率分别为7.1 × 103和7.0 × 104 Barrer。流程模拟结果表明，优化后的两段膜-深冷（Mem-Cry-Mem）组合工艺可将操作费用从1.28-2.24$/kg降低到0.41-0.54$/kg，冷凝温度从−131 ℃ −110 ℃提高到−105 ℃ −72 ℃。优化后的Mem-Cry-Mem组合工艺可获得纯度大于99%mol/mol的丙烷，能耗降低48.5- 73.8%。基于MMM的复合工艺在VOCs回收领域具有显著的技术经济潜力。
Efficient volatile organic compounds (VOCs) recovery could not only prevent air pollution, but also achieve potential economic benefits. However, the traditional VOCs recovery technology faces the challenges of high energy consumption and low recovery rate. In this work, membrane materials and the membrane-cryogenic hybrid process for propane recovery was designed and optimized by using molecular and process simulation, respectively. In detail, 152 kinds of MOFs/PDMS and MOFs/PTMSP mixed matrix membranes were predicted through molecular simulation. PCN-48/PDMS and ZIF-12/PTMSP mixed matrix membranes (MMM) with high selectivity up to 56.6 and 31.9 and permeability up to 7.1 × 103and 7.0 × 104Barrer were obtained. The process simulation results indicated that optimized two-stage membrane-cryogenic (Mem-Cry-Mem) hybrid process could reduce operating expenditure from 1.28–2.24$/kg to 0.41–0.54$/kg and increase condensation temperature from −131∼ −110 °C to −105∼ −72 °C. Furthermore, the optimized Mem-Cry-Mem hybrid process could get high purity (>99% mol/mol) propane with energy consumption reduced by 48.5–73.8%. The hybrid process based on MMM presented significant techno-economic potential in the field of VOCs recovery.
