Analysis of Permanent Gases and Noncondensable Hydrocarbons by Gas Phase Chromatography

1 Analysis of Permanent Gases and Noncondensable Hydrocarbons by Gas Phase Chromatography 

The most commonly encountered permanent gases are CO2, H2S, and N2 associated with gas or crude oil production and N2, CO, H2, and O2 found in refining and petrochemicals. 

The noncondensable hydrocarbons comprise the hydrocarbons having less than five carbon atoms methane, ethane, propane and butanes encountered in production refining will add the olefins and diolefins  

Chapter 3. CHARACTERIZATION OF CRUDE OlLS AND PETROLEUM FRACTIONS 

We will give two examples of analysis of these components, bearing in mind that the distinction between condensable and noncondensable hydrocarbons rarely holds in actual refining streams, most of them producing both classes of hydrocarbons simultaneously.
