Abstract
This paper is the continuation of our previous paper, which we refer to as numerical analysis of phase behavior and flow properties in an injection tubing during gas phase CO2 injection. Our study in this paper show the results during supercritcal CO2 injection under the same project. Geological CO2 storage technology is one of the most effective method to decrease climate change due to high injectivity and storage capacity and economics. A demonstration-scale CO2 storage project was performed in a deep aquifer in the Pohang basin, Korea for a technological development in a large-scale CO2 storage project. A problem to consider in the early stage design of the project was to analyze CO2 phase change and flow characteristics during CO2 injection. To solve this problem, injection conditions were decided by calculating injection rate, pressure, temperature, and thermodynamic properties. For this research, we simulated and numerically analyzed CO2 phase change from liquid to supercritical phase and flow characteristics in injection tubing using OLGA program. Our results provide discharge pressure and temperature conditions of CO2 injection combined with a pressure of an aquifer.
