DIPPR 801 - Evaluated Process Design Data

The DIPPR 801 database, used by engineers and scientists around the world, is an evaluated database of pure-component thermophysical properties. It includes over 2000 compounds of industrial importance. Thirty-two constant properties and fifteen temperature-dependent properties are included for each compound.

The DIPPR project was initiated in 1980 as a cooperative effort between many industrial companies. A brief history of the project will be presented along with a discussion of its foundational and guiding principals.

The evaluation process used in the project seeks to ensure thermodynamic consistency among related properties. Examples of the procedures used will be presented.
