Infos

Compiled by an expert in the field, the book provides an engineer with data they can trust. Spanning gases, liquids, and solids, all critical properties (including viscosity, thermal conductivity, and diffusion coefficient) are covered. From C1 to C100 organics and Ac to Zr inorganics, the data in this handbook is a perfect quick reference for field, lab or classroom usage. By collecting a large - but relevant - amount of information in one source, the handbook enables engineers to spend more time developing new designs and processes, and less time collecting vital properties data. This is not a theoretical treatise, but an aid to the practicing engineer in the field, on day-to-day operations and long range projects. - Simplifies research and significantly reduces the amount of time spent collecting properties data - Compiled by an expert in the field, the book provides an engineer with data they can trust in design, research, development and manufacturing - A single, easy reference for critical temperature dependent properties for a wide range of hydrocarbons, including C1 to ClOO organics and Ac to Zr inorganics

Carl L. Yaws, PhD is Professor of chemical engineering (retired) at Lamar University, in Beaumont, Texas. He has industrial experience in process engineering, development, modeling, and design at Exxon, Ethyl, and Texas Instruments. He is the author of 36 books and more than 1000 technical publications (papers, presentations, and chapters in books) in process engineering, property data, and pollution prevention. He is a leading authority on property data of chemical compounds for use by practicing engineers and scientists.

Critical Properties and Acentric Factor – Organic Compounds

Tabulation results

The tabulation is arranged by carbon number (C, C2, C3, … …) to provide ease of use in quickly locating the data by using the chemical formula. The compound name and CAS No (Chemical Abstracts Registry Number) are next provided. Values for molecular weight, boiling point, critical temperature, pressure, volume, density, and compressibility factor are given in the adjacent columns. The code for each property is also given. The last column provides the acentric factor.

In preparing the tabulation, a literature search was conducted to identify data source publications (1–93). Both experimental values for the property under consideration and parameter values for estimation of the property are included in the source publications. The publications were screened and copies of appropriate data were made. These data were then keyed into the computer to provide a database of values for compounds for which experimental data are available. The database also served as a basis to check the accuracy of the estimation methods. Upon completion of data collection, estimation of values for the remaining compounds was performed.

The estimates are primarily based on literature methods and proprietary procedures developed by the author. If initial analysis using the estimates is favorable, follow-up experimental determination is recommended.

A comparison of estimated and data values for critical temperature are shown in Figure 1 for a representative chemical family (alkanes). The graph shows favorable agreement of equation and data.

Example

In an engineering analysis, the critical properties and acentric factor are needed for ethylene (C2H4). Determine the critical properties and acentric factor for ethylene.

Inspection of the tabulation for critical properties and acentric factor yields:

Tc = 282.34 K

Pc = 50.41 bar

Vc = 131.0 ml/mol

rhoc = 0.2142 g/ml

Zc = 0.281

omega = 0.086
