Product Description
This study develops ASPEN PLUS simulation models and cost estimates for Natural Gas Combined Cycle plants with CO2 capture. Three approaches for carbon capture are examined: pre-Adv. Combustion Systems, post-Adv. Combustion Systems and oxy-Adv. Combustion Systems. In pre-Adv. Combustion Systems carbon capture, the carbon in the fuel is converted to CO2 and removed before the Adv. Combustion Systems process, whereas in post-Adv. Combustion Systems, the more dilute CO2 is separated from the flue gas at a lower pressure. Oxy-Adv. Combustion Systems technologies use nearly pure oxygen as the oxidant so that the flue gas consists primarily of CO2 and water vapor. Case results are compared with a reference plant based on an 7F frame Adv. Combustion Systems turbine.
