Effects of fine particulate matters on the wet-process desulfurized flue gas on CO2 adsorption by membrane
摘要
Abstract
The outlet of wet flue gas desulfurization(WFGD) system is the best location in the application of using membrane adsorption equipment in the removal of carbon dioxide from flue gas in coal-fired power plants. Wet-process desulfurized flue gas contains fine particulate matters which may deteriorate the performances of membrane. In order to obtain a better understanding on the influences of particulate matters on CO2 adsorption,this research investigated the capture process of carbon dioxide using polypropylene(PP) hollow fiber membrane from flue gas containing three kinds of particles(coal-fired fly ash,calcium sulfate,ammonium sulfate). The results showed that fine particulate matters reduced carbon dioxide removal efficiency due to deposition on the membrane surface. The results also demonstrated a negative correlation between the performance of CO2 adsorption by membrane and the deposit degree of fine particulate matters. Calcium sulfate affected the performances of CO2 adsorption by membrane the most among the three materials,and coal-fired fly ash had least influences on CO2 adsorption. It was difficult to back flush the fine particulate matters adsorbed on the surface of membrane,resulting invalid membrane.关键词
