Date Issued:

Summary:
Geologic storage of carbon dioxide (CO2) into deep saline aquifers is a promising strategy for mitigation of global atmospheric CO2 levels-a main cause of climate change. These aquifers have the capacity to safely store significant amounts of CO2 and are available worldwide. As such, reaction dynamics and multiphase transport accompanying CO2 injection in deep aquifers are important to understanding CO2 sequestration processes and therefore they have been extensively studied. Despite the comprehensive findings, there are still urgent needs for understanding of interactions between injected CO2 and resident fluids since these interactions could determine the total CO2 storage rate and capacity. The objective of this study is to investigate fundamental physics of water evaporation at different salinities under the CO2-rich environment. Microfluidic techniques visualize and quantify evaporation behavior of water in real-time in a simple 1D microchannel geometry. The detailed CO2-water interactions and underlying physics will be discussed.
