All chemicals default to 298.15 K and 101325 Pa onĬreation, unless specified. The library is designed around base SI units only for developmentĬonvenience. There are no solid models implemented in this interface at this time. There is also a N-phase flash algorithm available, FlashVLN.

Perform a flash calculation at 300 K and 1 bar, and obtain a variety of properties from the resulting object: > from thermo import ChemicalConstantsPackage, PRMIX, CEOSLiquid, CEOSGas, FlashPureVLS > # Load the constant properties and correlation properties > constants, correlations = ChemicalConstantsPackage. Create a pure-component flash object for the compound “decane”, using the Peng-Robinson equation of state.
