Abstract

During the carbon-dioxide capture and storage(CCS) process, is captured from large point source, and then injected and stored in stable geological structure for thousands and more years. Inside the captured flow, various impurities, such as , , argon, etc, are included inevitably. These impurities affect on the CCS process on various aspects. In this study, we designed and built experimental facility to evaluate the various impurity effect on the pipeline flow, and analyzed the effect of argon ratio and pressure variation on the pressure drop of flow. By comparing experimental data with 4 kinds of pressure drop model, we figured out and recommended the Cicchitti's model since it showed most accurate result among compared models in this study.
