API Data Book


Refinery Thermodynamics



Powerful Features

The API Data Book™ is the only official API standard that is a fully interactive software program. Read the standards, check the referenced methods, and run computations based on these methods.  The API  Data Book, co-published and updated annually by the American Petroleum Institute and EPCON, is the source for the latest, most accurate technical data, methods, and standards on petroleum refining officially sanctioned by the American Petroleum Institute.


Computation Capabilities

If you need to run calculations for characterization properties, distillation interconversions, pure component properties, mixture properties, or property estimation, the API Data Book is the complete solution. There is no longer a need to use a complicated simulation software package to  get the physical property data you need for process equipment sizing, fluid flow computations, etc.  Other software included in the API Data Book are flash point blending, natural gas mixture critical properties, reacting systems, liquid viscosity blending, and API conversions.


3-Phase Flash Calculations

THERMA Pro™ software included in the API Data Book 10th Edition provides an extremely accurate prediction of the second liquid (aqueous) phase versus using a process simulator.  This is due to the superior computation methods and integrated binary interaction parameters for all commonly used hydrocarbons and water.  Quickly obtain accurate prediction of the presence of a liquid aqueous phase which is vital to identify and avoid compressor damage and equipment corrosion problems.



Petro Fraction Properties

Characterization of petroleum fractions is vital to the petroleum refining industry for the accurate design and operation of process systems.  The API Data Book is the leading source for the latest, most accurate standards and methods for petro fractions and characterization properties.



Pure Component Properties

The API Data Book also includes pure component properties for nearly 700 components powered by the AIChE DIPPR Database®.  This provides the best available physical constants, temperature dependent and pressure dependent properties for use in your engineering work.
