HPC-PE (NO2.7)

This is a static-analytical phase equilibrium setup designed for accurate measurements at a wide temperature and pressure range and for a variety of fluids including toxic, explosive, sulphur containing, and corrosive mixtures at a wide pressure and temperature range. Both online and offline analysis of samples are facilitated.

Jannick Jooss gives ut a tour of the HPC-PE Rig, focusing on CO2 phase equilibrium and its impurities. Understanding CO2 behavior is crucial for its capture, transport, and storage: <iframe width="340" height="315" src="https://www.youtube.com/embed/8KdgCYw2k4s" title="🎥 Behind the Scenes from the HPC-PE Rig" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share" referrerpolicy="strict-origin-when-cross-origin" allowfullscreen></iframe>

In the design of the facility, there was an emphasis on accuracy, safety, and chemical compatibility with relevant components.

The temperature of the cell is accurately controlled using liquid thermal baths. Accurate syringe pumps will be used to inject the fluids under test and to set their pressure. A GC with thermal conductivity (TCD) and flame ionization detectors (FID) facilitates accurate composition analysis of most fluids. The novel sampling system is also prepared for electrolytes and more tricky components for which external analytical techniques can be applied. Some mixture systems will form multiple liquid phases. Hence, the cell has three sampling points with adjustable height.

The facility is located in the thermal laboratories of NTNU/SINTEF with its available infrastructures and services. Specifically, it could be a great advantage to utilize the ECCSEL TA8.3 CO2Mix setup for accurate gravimetric preparation of CO2-rich mixtures for calibration of the composition measurement systems. The facility is also directly adjacent to the offices of leading scientists in the field of SINTEF and NTNU.

Summary of specifications:

• Temperature: -60 – 150 (200) °C
• Pressure: 4 – 1 000 bar
• Have capabilities for electrolytes / brines
• Ideal for equilibria with multiple phases

The cell is specifically made for CCS, with a wide pressure range and robust material choices. It is expected that the cell will provide very high accuracy considering the wide pressure range.
