Novel refrigerants for hydrogen liquefaction Vapor-liquid-liquid phase equilibrium of CO2-H2O. Most of the models developed in that work are now made available, open-source, as part of Thermopack. The figure below shows a comparison of experimental data that was available at the time (symbols) and predictions from one of the equations of state (solid line), where there is coexistence between vapor and liquid at low pressures, and coexistence of two liquid phases at high pressures. In 2017, we carried out a comprehensive comparison and parameter regression of a variety of models to describe the thermodynamic properties of CO 2-H 2O. To recognize the process conditions where these risks may occur, a precise thermodynamic description of CO 2-water mixtures is needed.

Some of the risks in transport of dense-phase CO 2 are possible formation of hydrates that can plug equipment, and formation of free water that can cause corrosion. In the next few paragraphs, we will showcase a few examples (out of many), where Thermopack has been a crucial building block.Ī precise description of CO 2-H 2O mixturesĬO 2 capture, transport and storage (CCS) must be deployed on a large scale to mitigate global warming. Our hope and aim is that Thermopack can be helpful to our colleagues both in academia and in the industry that share our ambitions of contributing to a sustainable future for our children.

The software will be continuously updated as we make progress on the description of fluid properties. Thermopack can be downloaded from and can be compiled using the GNU and Intel FORTRAN compilers.

The graphical user interface is currently running on the Windows and Linux operating systems. The Python interface is also a building block for the Thermopack graphical user interface, where it is possible to plot thermodynamic phase diagrams with the most frequently used equations of state. The thermodynamic framework is easily interfaced from C/C++ and contains a flexible Python wrapper to make plotting easy. Thermopack is written in modern FORTRAN to handle heavy numerical computations associated with process and computational fluid dynamics (CFD) simulations. With the slogan of SINTEF in mind: “Technology for a better society” we want to share Thermopack with everybody, free of charge through the MIT open-source license. November 2020 – Thermopack – open source thermodynamics library Thus far, Thermopack has only been available to us, and it has been a much-appreciated powerhouse. Most of these equations of state have been developed by other research groups around the world, but some of them have been developed by us. A large selection of equations of state has been implemented in this software. Through decades of research, we have developed a software that performs thermodynamic calculations. The best choice of equation of state depends on the applications.īlog authors: Morten Hammer, Øivind Wilhelmsen og Ailo Aasen Thermopack software that perfoms thermodynamics calculation now available to all Some equations of state are very good when you have salts in your mixture, yet other equations of state are well suited to describe polymer solutions. Some have high precision but take time to provide the answer, while other are reasonably precise and very fast. There are many types of equations of state. Visualisation of a molecular dynamic simulation, by Åsmund Ervik, SINTEFĪll this information can be obtained from performing calculations with an equation of state, which is one of the main tools of thermodynamics. A typical task one is faced with in thermodynamics is that the temperature, pressure and composition of a fluid are known, but how dense the fluid is, how much energy it contains, or how much heat that must be supplied to change its temperature are unknown. Thermodynamics is a core topic used to describe the nature around us, or process equipment in the industry.
