Abstract

With the development of membrane separation technology, some traditional separation and purification methods have been replaced by membrane technology. Compared to traditional method, the membrane method has the advantages of small footprint, low energy consumption, safe operation and high removal rate. At present, membrane degassing has become a crucial step in ultra-pure water production for semiconductor industries, and it is also used in ink bubble removal and various wastewater treatment. This paper summarizes the advantages of membrane degassing compared with other gas-liquid separation methods, and introduces polymeric membrane materials used for degassing and their merits and drawbacks. The greatest challenge encountered in membrane degassing is the resistance to wetting phenomenon. This paper provides solutions to wetting phenomenon, which increases the possibility of widespread application of membrane degassing technology and the adaptability of membrane degassing technology to more demanding use scenarios. Finally, the application scenarios of membrane degassing technology are summarized and future prespectives are provided.

膜脱气技术的开发和新兴应用

随着膜分离技术的发展，一些传统的分离提纯方法已被膜技术所取代。与传统方法相比，膜法具有占地面积小、能耗低、操作安全、去除率高等优点。目前，膜法脱气已成为半导体工业超纯水生产的关键步骤，也被用于去除油墨气泡和各种废水处理。本文总结了膜脱气与其他气液分离方法相比的优势，并介绍了用于脱气的高分子膜材料及其优缺点。膜脱气过程中遇到的最大挑战是抗润湿现象。本文提供了解决湿润现象的方法，这增加了膜脱气技术广泛应用的可能性，并使膜脱气技术能够适应更苛刻的使用场景。最后，总结了膜脱气技术的应用场景，并对未来进行了展望。
