Investigation of the Phase‐Separation Point During CO2 Absorption in the DETA–Sulfolane–Water System

Carbon and Hydrogen, EarlyView.
Optical scattering diagnostics combined with generalized solubility product modeling enables quantitative prediction of phase separation in DETA–sulfolane–water biphasic CO2 absorbents. ABSTRACT The phase‐separation behavior of liquid–liquid biphasic amine absorbents is typically identified using bubbling reactors, where visual observation is employed ...

Digital documentation of railway tunnel inspection in Austria

Civil Engineering Design, Volume 7, Issue 1, Page 3-8, March 2025.
Abstract Infrastructure, especially railway tunnels, require continuous inspection to ensure their safety. Furthermore, the detection of damages at an early stage can improve their service life. These tasks represent a major challenge for those involved and the tunnel down time is a disruption in operation.

Experimental study on burning rate and flame geometry in construction tunnel fires under high geothermal conditions

Deep Underground Science and Engineering, EarlyView.
Abstract As tunnel construction advances in lengths and depths, the construction of tunnels in high geothermal environments has become increasingly common, raising significant fire risks. In this study, a 1:20 scale model tunnel test platform was constructed to investigate the effects of a high geothermal environment on fire behavior in tunnels during ...
