摘要
渗透汽化是一种绿色、高效的膜分离技术。为了能研制出性能理想的渗透汽化膜,渗透汽化过程的传质机理成为研究的热点。本文综述了渗透汽化传质过程的多种模型和理论,包括溶解扩散模型及其改进模型、孔流模型、Maxwell-Stephan理论、分子模拟方法等。比较了这些模型和理论的特点及应用范围,介绍了目前这些模型和理论的应用现状,并对其发展趋势进行了展望。
Pervaporation is a green, highly efficient technology of membrane separation. In order to develop the ideal membrane of pervaporation, the mass transfer mechanism for pervaporation becomes a research focus. This paper reviews several models and theories of the mass transfer process for pervaporation, including conventional and modified solution-diffusion model, pore flow model, Maxwell-Stephan theory, and molecular simulation. The characteristics and applicability of the models are compared. And the application status of the models and theories are also introduced. The research progress of the models is discussed.
