Abstract
The world's largest 2 million tons/year CO2 capture project from flue gas of coal power plants for EOR at Shengli oilfield of China was introduced. The blend amine absorbent performance, chemical absorption process, energy-saving method, and the layout area of engineering were interpreted. The health, safety, and environmental affect was analyzed and economic analysis was also carried out. The conclusion showed that the project has technical and economic feasibility. The study showed that the total energy consumption per unit product is 121.4 kg (standard coal equivalent (SCE))/tCO2, and the comprehensive regeneration energy consumption of the project is less than 2.2GJ/tCO2. The total investment of the project is 1329.4 million CNY; the after-tax internal rate of return reaches 8% when the ex-factory price of CO2 is 301.84 CNY /t(excluding tax).
