General comment This dataset is part of a set of LCI datasets for CCUS (carbon capture, utilisation and storage) technologies developed in Korea. This dataset represents 1 kg of CO2 captured from the flue gas of a Korean natural gas combined cycle (NGCC) power plant by post-combustion capture with an aqueous amine solvent, modelled as a CO2 feedstock. The power plant with capture supplies two functions, electricity and captured CO2. Following an underlying physical relationship, the changes caused by capture (additional natural gas to compensate the energy penalty and the reduced CO2 emission) are allocated to the captured CO2; the dataset therefore contains a negative fossil CO2 emission. Capture rate about 90%; CO2 purity at least 95 mol% (wet). CO2 compression, liquefaction, transport and storage are not included. The capture data are based on a feasibility study of a 3,000 t/d capture plant for NGCC flue gas (MEA solvent), cross-checked with Korean test results and international FEED studies. |
