Abstract: The carbon dioxide emission reduction is drawing increasing concerns globally. Particularly, the CO₂ capture technology applied in coal-fired power plants is one of the main methods to reduce CO₂ emissions from power plants on a large scale and the capture process is the basis of the technology. From the aspect of process design, the flue gas pretreatment and absorption processes of amine-based absorption are introduced, and the impacts of further desulfurization, flue gas cooling, absorption rate, plant adaptability, operational control and energy-saving technologies on CO₂ capture are analyzed, which can provide reference for large-scale CO₂ capture system design.

Key words: thermal power plant, flue gas, carbon capture, amine-based absorption, process design
