Abstract

Abstract

Static vortex was a way for progress intensification in wet flue gas desulfurization, and its status and trend were studied. The gas-phase flow field and the principle of the progress intensification were introduced. Various types of gas-liquid contact were compared, and the characteristics of various absorbents were analysed. The effects of the absorbent concentration, gas and liquid flow rate and SO₂ concentration on the desulfurization efficiency (η) and the overall gas phase mass transfer coefficient(K_ga) were determined and the mechanisms were explained. The research on cyclone absorber using mass transfer theory and development of mass transfer theory were analyzed, and the industrial applications were introduced. The results showed that static vortex flow was useful to improve desulfurization efficiency and mass transfer rate, and η and K_ga increased with the increase of absorbent concentration and gas-liquid flow rate; but with the increase of SO₂ concentration, η and K_ga decreased slightly(with maximum value of 7.1% and 0.75 s^-1, namely), and the range of η and K_ga in all operation conditions were 68.58%~97.63% and 5.08~8.46 s^-1, respectively. The results of the research could offer references for the industrial use of vortex flow technology for desulfurization.
