Simulis Thermodynamics extends its calculation and interoperability capabilities, useful for heat exchanger design and manufacture

ProSim, the process simulation software house, release a new version of Simulis Thermodynamics, its software component dedicated to thermo-physical properties calculation, and available as an MS-Excel add-in, a MATLAB toolbox or as a module pluggable in any other software that requires quality thermo-physical properties. This new version integrates additional calculation capabilities for properties (fugacity, internal energy), news flashes (temperature-volume, enthalpy-internal energy, internal energy-volume), as well as derivatives of available properties, with respect to temperature, pressure, or mole number. Additionally, Simulis Thermodynamics now offers the ability to automatically generate PSF (Process Simulation File) files, directly usable by the Aspen TASC (HTFS) software, for heat exchanger calculations.

These files contain properties for liquid and vapour phases such as specific heat, molecular weight, viscosity, thermal conductivity or surface tension, tabled with respect to temperature and pressure.

For diphasic mixtures, Simulis Thermodynamics provides enthalpy data such as temperature, pressure, enthalpy and vapour ratio.

Particularly relevant for exchanger manufacturers and their customers, this new feature allows TASC users with a limited thermodynamic database to access one of the richest thermodynamic packages available and enhance the quality of their exchangers design calculations at reasonable price.
