Abstract

Abstract: The economics of the carbon capture, utilization and storage(CCUS) technology is determined by the suitable technologies selected in the stages of the whole process of CCUS in coal-fired power plants. In this paper, the technologies adopted in the CO₂ capture, compression, transportation and enhanced oil recovery under different conditions are derived through itemized comparison. Then the influencing factors of the technologies are analyzed in the aspects of construction investment and operation costs with some optimization measures proposed. Through the comparison between three CCUS schemes assuming each with the capacity of 1 million tons per year for different power plant and oil field compositions, it is concluded that the CO₂ transmission distance is the major factor influencing the total construction cost. However, the cost increase from the average transmission distance may be compensated by the completion of medium-long term plan for common CO₂ transmission piping networks.

Key words: coal-fired power generation, carbon dioxide(CO2), capture, compression, transportation, enhanced oil recovery, technologies and economics, CCUS
