gas mixture thermal properties 1

[tj73]

I am trying to calculate the thermal properties of oxygen rich flue gas. If I know the composition of the gas (mole fraction of N2, O2, Co2, SO2, etc.), temperature and pressure, how could I calculate the thermal conductivity, heat capacity, heat transfer coefficient and viscosity, etc.? Could anyone know some website having these kinds of information. Thanks very much for your help in advance.

tj73,

If you have a copy of the TEMA (Tubular Exchangers Manufacturers Association) book, it has formulas for calculating mixed properties of gases.

Beware also that most of these quantities are mass-based, so you'll need to convert your mole fractions to mass fractions before averaging.

Thanks for the information. Unfortunately, I don't have this book at the moment. I will try to find if there is one in the company. Thanks. TJ

These properties are proportional to volume (or moles) except of course for heat capacity which is mass based.

GPSA 2145 has all the properties, just set up you own spreadsheet and convert and go.

You can have a look into

Go to the Calculators submenu on the left and the Gas Properties submenu will give you the calculation.
