This article calculates the carbon dioxide emissions intensity of coal-fired power plants

proposes the scale of the new generation coal-fired power generation unit carbon dioxide capture device

introduces the application of alcohol amine absorption method in large-scale carbon dioxide capture and storage utilization(CCUS/CCS) and the main technical and economic parameters. The CCUS/CCS technology route that reduces the carbon dioxide emissions intensity lower than 600 gCO2/kWh

detailed analysis is conducted on the impact on the original system and optimization schemes for steam and cooling water systems are proposed. The operating costs of CCUS/CCS under the condition of reducing carbon emission intensity lower than 600 gCO2/kWh and its impact on the unit's cost of electricity are estimated.
