CO2 Vol.% Is converted to mg / Nm3 using molecular weight 44,009 taken from http://www.kayelaby.npl.co.uk/chemistry/3_1/3_1_2.html after which it is multiplied by flow at STA level
Thereby the calculation becomes: CO2 Vol.% * Molecular weight * Flow Nm3 / h * 0.001 * 0.001 = [kg]
The above information about molecular weight can be found under Company Info
