Progress in Technology of Pipeline Transportation of Carbon Dioxide

Briefed here in the essay are the development of the carbon capture and storage technology as the key technology for carbon dioxide emission reduction over the recent years,and the superiority of the pipeline transportation of carbon dioxide. Elaborated are the present development situations of the technologies concerning pipeline transportation of carbon dioxide both at home and abroad,and relevant standards in association of the pipeline for carbon dioxide transportation. The physical properties of carbon dioxide,and the advantages and disadvantages of different transportation phase states are compared. And the fracture toughness control,corrosion and corrosion prevention technique of the CO₂ transportation pipeline are expounded. It is demonstrated via the research that owing to the obvious differences between the carbon dioxide's physical properties and the fracture toughness control of the carbon dioxide transportation pipeline and those of the natural gas transportation pipeline,it is needed to re-establish the prediction model for fracture expansion and fracture arrest of the carbon dioxide transprotation pipeline. Also needed is to properly control the contents of water and any other gas exclusion in the carbon dioxide transportation pipeline so as to prevent corrosion thereof.
