ProCOSMO

PSE for SPEED has started developing the ProCOSMO software, which allows users to estimate the properties of chemical compounds based on their sigma profiles by entering the compound name, CAS number, or molecular formula.

ProCOSMO can predict various properties, including vapor pressure, activity coefficient (gamma), vapor-liquid equilibrium (VLE), and solid-liquid equilibrium (SLE).

ProCOSMO Feature Examples

1. Selecting Database and Compound

  • There are two ways to search for compounds in our database;
    • Search Criteria
      • To choose a compound for further analysis, users can search by entering the CAS number, chemical name, or molecular formula.
    • Search Properties
      • Used for finding compounds based on molecular weight or boiling point, in case users want to specify the range of molecular weight or boiling point for analysis.

2. Vapor Pressure Calculation, Gamma Calculation, VLE, and SLE

  • Vapor Pressure Calculation
  • Gamma Calculation
    • Single point – to determine the gamma value for each component at a specified liquid mole fraction and given temperature.
    • Multiple points – to display the gamma and ln gamma values of each component at various liquid mole fractions.
  • VLE
    • Txy – to depict the phase behavior of binary mixtures by plotting temperature (T) against mole fraction (x) at a specified pressure.
    • Pxy – to depict the phase behavior of binary mixtures by plotting pressure (P) against mole fraction (x) at a specified temperature.
  • SLE
    • Ideal – to demonstrate the solubility behavior of a solute in a solvent, under the assumption that gamma equals 1.
    • Non-Ideal – to demonstrate the solubility behavior of a solute in a solvent, where gamma represents the actual value.
