High-pressure flow cell

The High-Pressure flow cell is set up for testing the diffusivity and permeability of gases, especially H₂, CO₂ and CH₄ through porous media at elevated pressures and temperatures of up to 35 MPa and 150 °C, respectively. Further on, the capillary breakthrough pressure of gases in water-saturated porous media can be detected. The flow cell is equipped with a sapphire window and an endoscopic camera to facilitate the visualization of gas permeation through the water-filled pores at breakthrough. An inline Raman spectroscope is applied to record changes in gas mixture compositions. The integrity of completion and sealing systems for hydrogen and carbon dioxide storage is the main focus of the studies being carried out. The setup comprises high precision pressure transducers on the upstream and downstream side. The setup is placed in an environment that is secured for working with compressed hydrogen.
