A study of the effects of friction, heat transfer, and stream impurities on the decompression behavior in CO2 pipelines

A transient multi‐phase outflow model is employed to study the effects of heat transfer and friction on the decompression behavior in CO 2 pipelines. The model's predictions are compared to measurements obtained from a number of shock tube experiments for gaseous phase CO 2 as well its various mixtures, typical of those found in the different capture technologies. Particular attention is paid to studying the impact of the stream impurities on the CO 2 mixtures saturation pressures and the decompression wave speeds given their direct influence on the pipeline's propensity to running ductile fractures. © 2012 Society of Chemical Industry and John Wiley & Sons, Ltd
