Abstract:
-Carbon capture has been an emerging technology for the past few years. Chemical absorption, one of the recognized methods in carbon capture, is the focus of the study. Aqueous ammonia has been established as a suitable solvent for chemical absorption. The study aims to determine Results show that both the percent absorption and the over-all gas mass transfer coefficient increases as the temperature increases from 5 to 13°C but decreasing beyond 13°C to 15°Cthe effect of temperature on the amount of carbon dioxide recovered from simulated flue gas in a wetted wall column using aqueous ammonia as absorbent. The temperature was varied in two-degree increments, from 5 to 15°C while maintaining a constant concentration. The percent absorption and the over-all gas mass transfer coefficient were calculated. It was observed that varying the temperature has an insignificant effect on both the percent CO2 absorption and the over-all gas mass transfer coefficient.
