API, the API Technical Data Committee, and EPCON International are pleased to provide the publication of the 10th Edition of the essential API Tech Data Book.  API has sponsored this important flagship project since the first edition of the API Tech Data Book was released in 1966.  For 50 years, the project has been managed by the API Technical Data committee, whose members include the petroleum industry's leading experts in thermodynamics and chemical engineering.  API member companies and EPCON International have worked  on improving the API Technical Data Book into a full electronic software and printed reference manual product for the past 18 years for the benefit of engineers working in the petroleum industry.  This is one of the many projects that API is pursuing to benefit its member companies.


Included is a property simulation software package with rigorous 3-phase flash capabilities that delivers over 130 API recommended methods.  The Data Book Explorer software interface enables quick searching of any text or phase within a specific chapter of the Data Book with single click access for direct calculation of these API methods within the property simulation software.


The purpose of the API Technical Data Book is to provide a critically reviewed compilation of the physical and thermodynamic data and correlations that are of most interest to petroleum refiners for practical application to process evaluation and equipment design.  Chapters on the following topics are provided in electronic, search-able software format along with software applications for implementation of recommended Data Book methods.
