SECTION 23Physical 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. 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.”

Ecuación para el Cálculo de la Separación Instantánea de los Hidrocarburos

F = L + V F = 1,0 L + V = 1,0

F.z i = moles del componente “i” en la carga.

V.y i = moles del componente “i” en el gas.

L.x i = moles del componente “i” en el líquido

F*z i = L*x i + V*y i
