3F. Effect of T and P on the Density of Liquid Hydrocarbon Mixtures Back to Main

This page is used to determine the effect of Temperature and Pressure on a hydrocarbon mixture using the Effect of Temperature and Pressure on the Density of Hydrocarbon Liquids graph (Figure 3.13). Figure 3.13 is a plot of C (density correlation factor), a density factor as a function of and . The density factor is used to correct the known density, , at one condition, to a density, , at another condition using the equation

Equation (3.20)

To calculate the density of the liquid hydrocarbons the Temperature, Pressure and Density of Known Conditions, the Temperature and Pressure of the Unknown conditions, and either the Critical Temperature and Pressure or the Mole % of the liquid must be entered into their entry spaces. To do so use the mouse to click the curser in the entry spaces and input the data. If the critical temperature and pressure are known click and shade the Known critical properties box and enter the critical values. If the critical temperature and pressure are not known click and deselect the known critical properties box and enter the Mole %. Once this has been done, select Run to execute the solution.

Please refer to Example 3.1 in page 57, Volume 1 for more information about critical temperature and critical pressure.
