Physical Property Data Services (PPDS)

Access to over 1,500 quality assured chemical compounds

Our PPDS Thermodynamic Properties Database and Calculation Suite provides accurate physical property data for use in a vast range of process engineering applications.

What is Physical Property Data Services (PPDS)?

Used daily throughout the world for over 30 years, whether for the chemical, process, energy or pharmaceuticals sectors, PPDS allows users access to over 1,500 quality assured chemical compounds based on actual measured data. Its sophisticated calculation package has the flexibility to perform anything from quick and basic everyday calculations to more complex thermodynamic problems.

what are the common applications for PPDS? 

  • Fluid properties
  • Separation
  • Petroleum fractions
  • Equipment sizing
  • Fluid flow
  • Phase envelopes
  • Heat transfer
  • Safety critical data


  • Determine how the vapour pressure of an organic solvent varies with temperature
  • Find the enthalpy-temperature curve for a multi-component mixture
  • Derive the mutual solubility of a hydrocarbon in water
  • Display the T-x and y-x plots for a binary mixture
  • Determine the phase envelope for a natural gas
  • Estimate, correlate and store the properties of a new chemical compound
  • Calculate the binary parameters for a thermodynamic model from experimental phase-equilibrium data
