摘要

Abstract

The application of spray towers for CO

capture is a development trend in recent years. However

most of the previous jobs were conducted in a cylindrical tower by using a single spray nozzle

whose configuration and performance is not good enough for industrial application. To solve this problem

the present work proposed a diameter-varying spray tower and a new spray mode of dual-nozzle opposed impinging spray to enhance the heat and mass transfer of CO

absorption process. Experiments were performed to investigate the mass transfer performance (in terms of the CO

removal rate (

) and the overall mass transfer coefficient (

which affect the absorption performance and the maximums of

respectively

under the experimental conditions. Furthermore

new correlations to predict the mass transfer coefficient of the proposed spray tower are developed in various CO

concentrations with a Pearson Correlation Coefficient over 90%.
