API Tech Data Book 9

API Tech Data Book 9

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

Whether you need to run calculations for characterization properties, distillation interconversions, pure component properties, mixture properties, or property estimation, the API Technical Data Book provides 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 applications include flash point blending, natural gas mixture critical properties, reacting systems, liquid viscosity blending, and special unit conversions, just to name a few.


The EPCON THERMA Flash software included in the API Tech Data Book 9th 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 Fractions Properties

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

Pure Component Properties

The API Technical 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.
