Covering more than 7,800 organic and inorganic chemicals and hydrocarbons, Transport Properties of Chemical and Hydrocarbons, Second Edition is an essential volume for any chemist or chemical engineer. Spanning gases, liquids, and solids, the book covers all critical properties (including viscosity, thermal conductivity, and diffusion coefficient).

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 use. By collecting a massive - 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 engineers with data they can trust
All critical properties are covered for ease of reference, including viscosity, thermal conductivity, and diffusion coefficient

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.

Viscosity of Gas – 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 regression coefficients are given in the adjacent columns. The temperature range for use is given in the next columns (TMIN and TMAX). The equation should not be used for temperatures outside this range. The next column provides the code for the tabulation. The last three columns provide values for gas viscosity at representative temperatures. The tabulation is applicable to gas at low pressure.

In preparing the tabulation, a literature search was conducted to identify data source publications (1–100). 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 empirical procedures developed by the author. If initial analysis using the estimates is favorable, follow-up experimental determination is recommended. This is especially true for highly polar and high-molecular-weight compounds.

A comparison of calculated and data values is shown in Figure 1 for a representative compound. The graph shows favorable agreement of equation and data.

Figure 1Viscosity of Gas for Carbon Monoxide

Example

In an engineering analysis, gas viscosity is needed for carbon monoxide (CO) at 400 K. Determine the gas viscosity of carbon monoxide at this temperature.

Substitution of the coefficients from the tabulation and temperature yields:

ngas = 18.0493 + 6.3753E-01 × 400 – 3.5748E-04 × 4002 + 1.0287E-07 × 4003

ngas = 221.83 micropoise
