Abstract

Abstract: A two-dimensional mass transfer-mixing unit model for tray efficiency in the spray regime was proposed in this paper. By means of this model, the influence of the parameters such as single unit drag-up,inter-unit exchange fraction and circulating fraction of liquid on tray efficiency can be easily simulated. It provides a theoretical basis for the development and design of trays operating in the spray regime.
