Abstract
Carbon dioxide has been identified as a major greenhouse gas responsible for a large part of the enhancement of global warming. CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> capture and storage (CCS) from power plants is drawing increasing interest as a potential method for the control of greenhouse gas emissions. Technically, the capture of CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> from the flue gas of power plants, using a monoethanolamine (MEA) absorption process is a viable shortcut to medium term strategy for the mitigation of the atmospheric CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> emissions from large point sources. An economical performance study for a CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> removal plant from flue gas of a NGCC syngas-fired power plant was performed, based on absorption/regeneration process with MEA solutions, using ASPEN Plus. The conclusion is that the efficiency drop due to CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> removal plant is approximately 12.9%; and the cost of CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> captured and the cost of CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> avoided are respectively 13 euros/tCO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> and 18 euros/tCO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> . In order to popularize large-scale CCS to power plants, technology improvement is greatly needed.
