Dippr 801 [2021] -

Whether you are a student learning Aspen Plus, a process engineer checking a pump curve, or a researcher developing a new solvent, DIPPR 801 is the benchmark you can trust.

For decades, engineers have sought a single, reliable source for these critical properties. Enter —the industry’s gold standard database for thermophysical properties of pure compounds. If you simulate a distillation column, size a pump, or design a reactor, chances are high that your work relies on DIPPR data. dippr 801

With DIPPR 801, you have equations fitted to the best experimental data available—often with uncertainties under 1-2%. The result is a design that works the first time, saving millions in rework and downtime. Whether you are a student learning Aspen Plus,

Imagine designing a heat exchanger for a new refrigerant. The heat transfer coefficient depends on liquid thermal conductivity and viscosity. Using a generic estimation method (like a group contribution model) might give errors of 10-20% in these properties. That error compounds into undersized or oversized equipment. If you simulate a distillation column, size a

DIPPR 801: The Gold Standard Database for Physical Properties in Process Engineering

The result is the , a critically evaluated collection of over 2,000 pure compounds, ranging from common solvents and hydrocarbons to specialty refrigerants and monomers. For each compound, the database provides temperature-dependent prediction equations for 36 distinct properties.
