Abstract

This paper provides an overview and analysis of the current research on swirl separators in the field of gas-liquid separation, emphasizing their utility in processes such as pre-degassing of produced liquids. The review encompasses the development, fundamental design, internal flow characteristics, and operational mechanisms of swirl separators. A comparative analysis of different swirl separator designs is also presented, highlighting the limitations of single-structure parameter optimization and static system analysis in capturing the intricacies of actual operational conditions. The study notes that enhancements in separation efficiency have been achieved through modifications to the external structure and internal flow field of swirl separators by researchers globally, thereby potentially increasing industrial productivity. With the expanding application of gas-liquid swirl separation technology, quantitative numerical research on swirl separators and their internal flow fields is deemed essential for engineering applications. The findings of this research are intended to inform the design and application of gas-liquid swirl separators.
