Full visual PVT system for CO2 solubility trapping studies


 The FULL VISUAL 300-HC FLUID-EVAL ANALYSER is specifically designed for brine-CO2 thermodynamics studies in CCUS programs. With a sapphire window and a short-wave infrared (SWIR) video system, it enables visual observation and precise determination of the bubble point of the CO2-brine complex. Diffusion rate of CO2 in brine can also be determined. It provides a controlled environment for in-depth investigations into CO2-brine interactions and phase behavior. This cell is valuable for CCUS research, providing insights into CO2 behavior. It contributes to decision-making in carbon capture, utilization and storage. The Full Visual PVT cell is most probably the most accurate method to measure the solubility of CO2 in aquifer reservoir, which is a key step to calculate the CO2 storage capacity of a specific site (solubility trapping).
The system can also be equipped with a Salt Crystallization System (SCS) to detect salt deposition in CO2 brine complexes by measuring visible light transmittance through fiber optic probes in a PVT cell. It helps identify the onset conditions for salt precipitation, aiding in understanding and mitigating potential issues in CO2 storage and related applications.
