Thermodynamic models to accurately describe the PVT xy-behavior of water / carbon dioxide mixtures
Carbon dioxide/water (CO2/H2O) mixtures are of much interest in carbon capture and storage, atmospheric science, in the description of human lungs and in the processing of food and beverages. We present a comprehensive comparison of thermodynamic models for describing their PVTxyPVTxy behavior, i.e....
Thermodynamic modeling with equations of state: present challenges with established methods
Equations of state (EoS) are essential in the modeling of a wide range of industrial and natural processes. Desired qualities of EoS are accuracy, consistency, computational speed, robustness and predictive ability outside of the domain where they have been fitted. In this work, we review present ch...
Key findings and recommendations from the IMPACTS project
The IMPACTS project investigated how impurities affect the design and operation of CO2 transport and storage processes. Experimental work and modelling have advanced the state of the art in the areas of how impurities in CO2 affect thermo-physical properties, fluid flow, corrosion, and reservoir che...
Techno-economic evaluation of the effects of impurities on conditioning and transport of CO2 by pipeline
This paper describes a detailed technical and economic assessment of conditioning and transporting 13.1 MTPA CO2 with impurities in an on-shore pipe-line over a distance of 500 km. The impurities that are included in the study represents 5 mol% residuals from air-components (N2 and O2) and 10 mol% r...
From droplets to process: Multilevel research approach to reduce emissions from LNG processes
Investigation of non-ideal behavior of plate-fin heat exchangers in LNG services
Using a heat exchanger with several parallel channels in boiling services, static instabilities like the Ledinegg instabilities can occur, resulting from a combination of unfortunate operating conditions and the heat exchanger design. Ledinegg instability is characterized by different flow rates in ...
The Next Generation Reference Equations of State
An Extended Corresponding States Equation of State (EoS) for CCS Industry
For a good design of all the processes in Carbon Capture and Storage, the thermodynamics of the CO2 and CO2 mixtures should be accurately predicted. Among these mixtures are CO2-water systems that are very difficult to deal with due to the polar nature. In this work we suggest a new extended corresp...
