Evolution and Size Distribution of Solid CO<sub>2</sub> Particles\nin Supercritical CO<sub>2</sub> Releases

Abstract

CO<sub>2</sub> transportation safety is important for the successful\nimplementation of carbon capture and storage (CCS) projects. The formation\nof solid CO<sub>2</sub> is a unique phenomenon in high-pressure CO<sub>2</sub> release. The evolution and size distribution of dry ice particles\nhave a significant impact on assessment of the consequences of accidental\nrelease of supercritical CO<sub>2</sub> from a pipeline. The motivation\nis to investigate the particle behavior and size distribution and\nunderstand how the impact factors affect them. An experiment with\nvarious measurement methods was developed to carry out controllable\nCO<sub>2</sub> release from a high-pressure vessel. The macroparameters\nsuch as jet configuration, temperature, and velocity were recorded.\nMeanwhile, motion of the microparticles was also analyzed. In addition,\nthe effects of initial pressure and temperature on the particle size\ndistribution were investigated. The results showed that the agglomeration\ninfluenced the size distribution at different positions of the jet.
