【 摘 要 】

The paper simulate the traditional and the new technologies of carbon capture on the basis of the 330 MW power plant unit by using Aspen plus. Meanwhile, by checking linear relationship between load and steam flow rate, the model of the unit steam cycle is set up, verifying the accuracy of the model. And put the two kinds of process equipment into the unit steam cycle, to analyze the factors affecting the steam cycle of the two technologies. The main conclusions are drawn as follows: The new technology has lower heat consumption than the traditional technology as well as the extent of the impact of the unit output power. So the new technology has advantages on energy saving. Also, the study of the characteristics of the integrated system is conducted, obtaining that it has different impacts on the unit output power when extracting from different steam turbine pressure ports to heat the carbon capture system, which will give a reference for units operation with the new carbon capture system.
