Abstract:

CO2 is the main greenhouse gas. The reduction of CO2 emissions to cope with climate change has become an international consensus. Industrial flue gas is considered to be an important source of CO2 emissions. The characteristics of industrial flue gas CO2 emission, the main test and treatment technology were studied and analyzed. The CO2 concentrations in power plant, steel and cement flue gas are 9.7%-15%, 2%-28% and 11%-29%, respectively. CO2 testing methods mainly include non-dispersive infrared absorption, gas chromatography, spectroscopy, and chemical absorption, etc. Among these, the non-dispersive infrared absorption method is the most mature in application and is the mainstream technology for fixed source CO2 testing at present. CO2 capture technologies mainly include absorption, adsorption, membrane separation, and cryogenic methods. Among these, the chemical absorption method is widely used for capturing low concentration CO2 (volume concentration ≤30%). The purpose of this study is to provide reference for the subsequent large-scale industrial carbon reduction.

Key words: industrial flue gas, CO2 emission, capture technology, test method
