【 摘 要 】

The paper proposes a new technology of CO2 capture which is based on a 350MW coal-fired power plant. The traditional and the new CO2 capture model was built by using software Aspen plus. To study the effect of operating parameters on CO2 capture efficiency, ammonia escape and the CO2 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 desorption. The new technology leads to the high rate of reaction as well as the high NH3 utilization in absorption process. On the other hand, the capture volume of CO2 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.
