A preliminary assessment of the initial compression power requirement in CO2 pipeline “Carbon Capture and Storage (CCS) technologies" [PDF]

open access: yes, 2016
CO2 captured from fossil-fueled power generation plants is said to be economically transported via pipelines over long distances. The CO2 must be compressed to pipeline specifications using compressors and pumps that are driven by gas turbine (GT) or ...
