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 kiln flue gas of a Korean cement clinker plant by post-combustion capture with an aqueous amine solvent, modelled as a CO2 feedstock. The clinker plant with capture supplies two functions, clinker and captured CO2. Following an underlying physical relationship, the changes caused by capture (capture plant inputs and the reduced CO2 emission of the kiln) are allocated to the captured CO2; the dataset therefore contains a negative fossil CO2 emission. Low-pressure steam and electricity for capture are supplied independently of the clinker plant. Capture rate about 90%. CO2 compression, liquefaction, transport and storage are not included. The capture data are based on a 5 t/d demonstration plant at a Korean cement plant, cross-checked with international cement capture projects. |
