Opportunities and Challenges Associated with CO2 Compression and Transportation During CCS Activities
The majority of research on carbon capture and storage has been on capture, injection,and subsequent monitoring of the CO2 plume in a secure geologic setting, with little attentionpaid to compression or pipeline transport. Opportunities for improved compression and transportefficiency and cost include precise compressor design made possible through a more thoroughunderstanding of the behavior of mixed CO2 streams near the critical point of CO2; betterintegration of CO2 capture and compression, especially with respect to the use of the heatgenerated during interstage cooling; improvement of compression efficiency through theexploration of compression pathways that also include liquefaction and pumping of the CO2;advanced compressor design, such as the shockwave technology under development by Ramgen;development of compressor electric drives and associated components that can operate at higherpower rankings more reliably and efficiently; and development of a large-scale CO2 pipelinenetwork and the establishment of common carrier CO2 stream composition requirements.;;View/Download Document
