Density of flue gases

Densit of flue gases The density of the flue gases is affected by pressure and temperature. In case of small differences in pressure, the density at different gas temperatures can be calculated (kg/m3):

where is the gas-mix density at 0 C, 100kPa is the gas mix temperature

Densit of molecules in the flue gas mi The total density of a flue gas mix can be calculated from the sum of (partial pressure of component * component density) Densities of part components (kg/Nm3) Component CO2
