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

Authors


Abstract

A transient multi-phase outflow model is employed to study the effects of heat transfer and friction on the decompression behavior in CO2 pipelines. The model's predictions are compared to measurements obtained from a number of shock tube experiments for gaseous phase CO2 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 CO2 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
