API - TDB CHAPTER 4
Technical Data Book Chapter 4 - Critical Properties
|Publication Date:||1 January 1982|
In 1966 the first edition of the Technical Data Book--Petroleum Refining was published by the American Petroleum Institute and included a chapter on the estimation of the critical properties of hydrocarbons. The Subcommittee on Technical Data of the Division of Refining, which was responsible for the publication, noted at that time that there was a paucity of both data and correlations for the critical properties of mixtures. This resulted in a project being initiated under Professor Webster B. Kay at The Ohio State University to determine critical properties of hydrocarbon mixtures. This project continued for six years and obtained data on 120 different systems and in itself dwarfed all previous data available.
From 1970 to 1973, using all new data and correlations available, the Data Book group in the Department of Chemical Engineering at The Pennsylvania State University revised and extended Chapter 4. Detailed results of the methods and of the evaluations using the experimental data are available in Documentation Report No. 4-73 available from University Microfilms, Ann Arbor, Michigan. In 1980 Figures 4D3.1, 4D3.2, and 4D4.1 were replaced with Procedures 4D3.1 and 4D4.1. These procedures are documented in Documentation Report No. 2-81 also available from University Microfilms.
The major work on this chapter was carried out by Mr. Calvin F. Spencer, Research Assistant in Chemical Engineering, reporting to Drs. Thomas E. Daubert and Ronald P. Danner. Miriam K. Maslanik, Research Assistant in Chemical Engineering, aided in preparing the 1980 update. The chapter coordinator for the Subcommittee on Technical Data was Joseph E. Wolf of Amoco Oil Company.
From 1983 to 1985, methods for prediction of critical properties for pure hydrocarbons and defined hydrocarbon mixtures were reevaluated leading to the current revision. Mr. J. Richard Elliott, Research Assistant in Chemical Engineering, carried out much of the work. The revisions are documented in Documentation Report No. 4-85 available from University Microfilms. Dr. J.G. Spiro, Gulf Canada, Ltd. was the chapter coordinator for the Technical Data Committee.
In 1985 methods for prediction of critical properties of undefined mixtures were reviewed and revised. Dr. M. R. Riazi, Assistant Professor of Chemical Engineering, carried out this work. Revisions are documented in Documentation Report No. 2, 3-86 available from University Microfilms. Dr. T. E. Daubert directed the work and Dr. J. G. Spiro was coordinator for this portion of the work.
