An Economic Comparison of CO2 Pipeline Transport Processes for Dongfang 1-1 Gas Field EGR Program
As more and more natural gas fields with high content of CO2 have been exploited, it is a strategic significance to capture and take good use of the waste gas while reducing CO2 emission to atmosphere. Pipelines have been identified as the primary means of transporting CO2 from point-of-capture to storage sites, but there is little published work on the economics of CO2 pipeline transport study either exclude transport costs or assume a given cost per tonne of CO2 in addition to capture costs.This paper simulates the CO2 pipeline transport processes of different diameters by liquid and supercritical phase, and estimates the total costs of different transport cases. By comparing the economic value of different cases comprehensively, the optimal transport option for Dongfang 1-1 gas field EGR program has been analyzed.
