SECTION 23

Physical Properties This section contains a number of charts, correlations, and procedures for the prediction of physical properties of hydrocarbons and components found with them. Fig. 23-1 lists the nomenclature used in this section. Fig. 23-2 is a table containing frequently used physical properties for a number of hydrocarbons and other selected components. Immediately following is a detailed list of references and footnoted explanation for the values in Fig. 23-2. 23-2. Physical properties for eighteen selected compounds can be found in GPA Standard 2145, “Table of Physical Constants of Paraffin Hydrocarbons and Other Components of Natural Gas.”
