ProSim announces the release of DIPPR L08+

ProSim announces the release of DIPPR L08+, an extended database providing thermodynamic and physical properties of a large number of chemical components.

The properties covered include data for 29 fixed-value properties (molar weight, critical temperature, critical pressure, etc.) and correlation coefficients for 15 temperature-dependent properties (liquid and vapor heat capacity, vapor pressure, liquid and vapor viscosity, etc).

DIPPR L08+ is based on the 2008 public release of AIChE's (American Institute of Chemical Engineers) DIPPR® 801 (Design Institute for Physical Properties) database, the main reference for the thermophysical properties of pure components. The data stored went through rigorous a review and validation process that ensures their quality and reliability. Following an agreement with BYU (Brigham Young University) in 2003, ProSim joined the very few companies allowed to distribute the original DIPPR® 801 database worldwide, within its thermodynamic properties calculation or process simulation software.

The last public DIPPR® 801 database contains the properties of 1 944 compounds, including all industrially relevant components. ProSim's DIPPR L08+ is an enriched version of this database, providing the latest data for 2 128 components. Additional information was gathered and tested through in-depth research projects and studies conducted by ProSim thermodynamic experts. "With DIPPR L08+, users have access to accurate and complete pure components thermodynamic and physical properties. This guarantees the most reliable results when performing thermodynamic calculations and process simulation, in particular with ProSim's software", explains Olivier Baudouin, Process Manager of ProSim.

DIPPR L08+ completes the numerous features of ProSim's thermodynamic package, already regarded as one of the most flexible and reliable on the market. DIPPR L08+ is available as standalone software, provided with Component Plus and Simulis Properties (ProSim's free pure component properties database management software) or as an option to any ProSim's package, in which it can be used seamlessly.

The standalone version can be purchased online from ProSim's web site ( For more information please visit the DIPPR page.
