Lime carbonate composition

[edit / update model]
This category contains data and methodology for calculating the greenhouse gas emissions from lime manufacturing using the carbonate composition of the raw material that enters the kiln. Emissions are disaggregated on the basis of the types of carbonates used and are corrected for LKD and the fraction of each carbonate species that remains uncalcined following lime production.

This methodology and associated data is sourced from the WRI Greenhouse Gas protocol worksheets but ultimately follows the IPCC 2006 Guidelines for National Greenhouse Gas Inventories. This cateogry represents the IPCC's Tier 3 approach.

Use the drill-down carbonateType and enter the required profile item values listed below.

Carbonate specific 'emissions factor'. The mass ratio of carbonate-sourced carbon to CO2 produced during calcination
Fraction calcination achieved for carbonate (decimal fraction; 0-1). Default of 1.0 assumed if none explicitly specified
Fraction calcination achieved for carbonate type within lime kiln dust (decimal fraction; 0-1). Default of 1.0 assumed if none explicitly specified
Quantity of carbonate calcined
Quantity of lime kiln dust generated. By default, this quantity is assumed to represent the dust generated specifically in association with the carbonate type under consideration. Alternatively, this value can be used to represent the total quantity of lime kiln dust (i.e. across all carbonate types), with the fraction for the specific carbonate type under consideration specified separately.
Weight fraction of the carbonate type in lime kiln dust (decimal fraction; 0-1). If not specified, a default value of 1 is assumed, which implies that the entire quantity of lime kiln dust specified represents the carbonate type under consideration. If no specific data on the breakdown of lime kiln dust by carbonate type is available, the fractions of each type within the raw kiln feed can be used as a proxy measure
