Application of the Pulse Tracer Injection Method for Estimating the Mass Transfer Efficiency at Extremely Low Irrigation Densities for the Case of Structured CY Sulzer Packing

摘要

The liquid flow pattern of the countercurrent phase water isotope exchange process used for the removal of tritiated water vapor from gases has been studied via the pulse injection of a tracer into a liquid flow. A specific feature of this process is an extremely low water irrigation density in a column. Based on the performed experiments, the liquid holdups have been calculated and the liquid flow pattern has been determined. It has been demonstrated that the standard estimation of the longitudinal mixing effect on the masstransfer characteristics of this process has a limited character and may result in incorrect conclusions at a low irrigation density on packings.
