This paper investigates the effects of impurities on pipeline sizing for dense phase and gaseous phase pipeline transportation using a series of twelve CO2 impurity scenario compositions. The scenarios have been selected as worst-case compositions that are representative of plausible CO2 streams from different capture technologies and industry sources. Two analyses are presented:
i) an initial hydraulic analysis, conducted for a single point-to-point pipeline transporting a fixed flow rate of CO2 in either the dense phase or gaseous phase and
ii) a sensitivity analysis to evaluate the effects of inlet pressure, ambient temperature and mass flow rate and pipeline size and identify an optimum pipeline size to handle each scenario in a hydraulically efficient manner.
The inlet and outlet temperature and pressure ranges for each pipeline were selected based on a detailed analysis of the thermodynamic properties of the different streams, which is also discussed. As a result of the study, conclusions are drawn regarding the compositions that present the most challenge with respect to hydraulic efficiency and pipeline costs. In addition, guidance is provided on the specification of inlet conditions to improve the hydraulic performance of the pipeline.
This work forms part of a study supported by IEAGHG on the “Impact of CO2 Impurity on CO2 Compression, Liquefaction and Transportation”. The study was commissioned to identify potential impurities and address the consequences of their impact on CO2 transportation.
