Aspen Properties Physical Property Database

By using a consistent physical property database that is extensive, flexible, and reliable, we ensure the accuracy of the model and reduce engineering time.

The Aspen Properties database and its supporting development tools have led the industry for the past 40 years by providing thermodynamic properties throughout the entire lifecycle of chemical processes. When Aspen Properties was first launched in 1983, the online provision of property data for chemistry and chemical engineering brought about a significant transformation in the discovery, development, and operation of chemical processes. AspenTech continues to lead the application of digital properties through ongoing additions of new property methods, innovations such as electrolyte property systems, strong partnerships with the global research community through close relationships with the National Institute of Standards and Technology (NIST), innovations in generalizing workflows to enable users to develop new property models, and improvements in properties related to carbon capture amine systems.

basic information

Recently, we have been incorporating an increasingly rich set of physical property data for modeling bio-based raw materials and bio-derived chemical products. AspenTech has not only expanded the range of Aspen Properties to support AspenTech software across all simulation tools (Aspen Plus family, Aspen HYSYS family, Exchanger Design & Rating), but has also included the Aspen Unified PIMS environment to enable the construction of a consistent workflow between design overviews and digital twin environments, as well as operational planning and optimization systems.
