The PPDS Suite of software packages and databases is used daily throughout the world to provide quality-assured physical property data (numeric values with associated uncertainties) for a wide range of process engineering applications.
For over 35 years, this suite has used proven methods in conjunction with validated data to answer common questions such as:
- How does the vapour pressure of an organic solvent vary with temperature?
- Find the enthalpy-temperature curve for a multi-component mixture.
- What is 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.
- Determine the binary parameters for a thermodynamic model from experimental phase-equilibrium data.
Ease-of-use has always been an important feature of these packages. The current versions combine the underlying technology with Windows GUIs to provide flexible packages, available as either stand alone or client/server versions.
PPDS provides traceability on the data returned by the software by giving uncertainty estimates on the numerical values of the properties.
With the ability to create and maintain user databanks for pure components and binary systems, the PPDS Thermodynamic Properties Suite allows users to use new and existing measured data into their everyday calculations.
There are three main modules in the suite:
- PPDS for Windows- The thermodynamic calculation package
- DataExpert- The Pure Component property regression tool
- PFit- The BIP fitting tool
With a variety of interfaces available to suit almost every situation, PPDS is the ideal solution for a more cost effective use of key thermodynamic information across a company.
In addition, the PPDS web browser application provides on-line access to thermophysical properties calculations.
