Glass production carbonate methodology


The category /business/processes/production/glass/carbonate contains data and a methodology for calculating the greenhouse gas emissions associated with the production of glass.

The category uses specific quantities of various carbonate species - used as feedstock in the glass industry and the primary source of carbon - for calculating CO2 emissions, and represents the IPCC Tier 3 methodology.

To use this category, simply create a profile item (there are no drill options to specify). Next, specify the quantities of each carbonate mineral using the massCalcite, massMagnesite, massDolomite, massSiderite, massAnkerite, massRhodochrosite, and massSodaAsh, profile item values. Any carbonate types not used need not be specified. The calculation returns the quantity of CO2 emitted assuming 100% calcination of each.

Users can override this assumption by specifying the actual calcination fraction (as a decimal between 0-1) using the fractionCalcite, fractionMagnesite, fractionDolomite, fractionSiderite, fractionAnkerite, fractionRhodochrosite, and fractionSodaAsh profile item values.

Note: the stoichiometric ratio for Ankerite => CO2 has be taken as the midpoint (0.44197) of the range (0.40822 − 0.47572) specified in the IPCC documentation.
