Abstract
A swirl plate is widely used in industry for gas-liquid mass transfer, reaction and removal of droplets from gas flow. The maximum efficiency superficial gas velocity is a key parameter in the design and application of swirl plate demisters, but currently there is no calculation method available. In this paper, a set of swirl plate demister experimental device was built, the separation efficiency, maximum efficiency and the corresponding superficial gas velocity of water and DOS droplets using three types of swirl plate demisters were determined. Furthermore, based on the calculation of critical gas velocity for droplet re-entrainment, a calculation formula for predicting this maximum efficiency superficial gas velocity was proposed. The results show that the predictions are in good agreement with literature data and experimental results. The research provides essential support for predicting the maximum efficiency superficial gas velocity during the design and application of a swirl plate demister.
期刊介绍：
ChERD aims to be the principal international journal for publication of high quality, original papers in chemical engineering.
Papers showing how research results can be used in chemical engineering design, and accounts of experimental or theoretical research work bringing new perspectives to established principles, highlighting unsolved problems or indicating directions for future research, are particularly welcome. Contributions that deal with new developments in plant or processes and that can be given quantitative expression are encouraged. The journal is especially interested in papers that extend the boundaries of traditional chemical engineering.
