Decarbonization generally involves physical absorption and chemical absorption processes (such as the thermal potassium alkali method, the alcohol amine method, and NaOH solution). In which fields are these different processes suitable for use? As far as I understand, physical absorption is commonly used for carbon capture in power plants, while chemical absorption is more frequently used in chemical plants. However, refineries and ethylene plants seem to employ different chemical absorption processes – for example, ethylene plants tend to use the alcohol amine method and NaOH solutions, whereas refineries and fertilizer plants use the thermal potassium alkali method. I’m not sure what causes this difference This post was last edited by lymountain on 2009-4-14 14:52]
