The paper proposes a new technology of CO 2 capture which is based on a 350MW coal-fired power plant. The traditional and the new CO 2 capture model was built by using software Aspen plus. To study the effect of operating parameters on CO 2 capture efficiency, ammonia escape and the CO 2 capture volume of the two techniques, a further comparative analysis was performed. Getting the following conclusion that the new technology has an obvious advantage on the process of carbon absorption and

On the other hand, the capture volume of CO 2 of the new technology is 31% more than the traditional technology in desorption process. Moreover, the regeneration power consumption of the new technology is only 42.6% of the traditional one. So, the new technology is more energy-saving and efficient.
