Introduction and Background Information

Recently the worsening global warming issue caused by emissions and accumulation of greenhouse gases in the atmosphere has become a subject of public concern. Carbon dioxide (CO₂) is widely considered as the predominant contributor of greenhouse gases. The post combustion CO₂ capture technology is one of the commonly used technologies for dealing with CO₂ emissions. The absorption of CO₂ into aqueous amine solution is regarded to be one of the most promising technologies for post combustion CO₂ capture due to its maturity, cost effectiveness, and capacity to handle large amounts of exhaust streams. In this chapter, the general information about the CO₂ capture is present. The comparison of the several technologies for CO₂ capture is also discussed in order to give the detail about the advantages and disadvantages for each technology. In addition, the detailed introduction about the post combustion CO₂ capture by using the amine based solvent is provided in this chapter.
