Annex VIII
United Kingdom
Annex VIII is amended as follows:
- (1)
The title of Annex VIII is replaced by the following:
‘ Activity-specific guidelines for the production of lime or calcination of dolomite or magnesite as listed in Annex I to Directive 2003/87/EC ’;
- (2)
Section 2 is amended as follows:
- (a)
in the first paragraph, the introductory phrase is replaced as follows: ‘In the production of lime or calcination of dolomite or magnesite, CO2 emissions result from the following emission sources and source streams:’;
- (b)
in the first paragraph, first indent, the wording is replaced as follows: ‘calcination of limestone, dolomite or magnesite in the raw materials’;
- (c)
under subsection 2.1.1, Combustion Emissions, the wording is replaced as follows: ‘Combustion processes involving different types of fuels (e.g. coal, petcoke, fuel oil, natural gas and the broad range of waste fuels) that take place at installations for the production of lime or calcination of dolomite or magnesite shall be monitored and reported in accordance with Annex II.’;
- (d)
under subsection 2.1.2, Process Emissions, first paragraph, the wording is replaced as follows: ‘Relevant emissions occur during calcination and from the oxidation of organic carbon in the raw materials. During calcination in the kiln, CO2 from carbonates is released from the raw materials. Calcination CO2 is directly linked with the lime, dolime or magnesia production. On an installation level, calcination CO2 can be calculated in two ways: based on the amount of calcium and magnesium carbonate from the raw material (mainly limestone, dolomite and magnesite) converted in the process (calculation method A), or based on the amount of calcium and magnesium oxides in the products (calculation method B). The two approaches are considered to be equivalent and can be mutually used by the operator to validate the results of the respective other method’;
- (e)
under subsection 2.1.2, ‘Calculation Method A: Carbonates’, the introductory phrase is replaced as follows: ‘Calculation shall be based on the amount of calcium carbonate and magnesium carbonate – and where relevant, of other carbonates – in the raw materials consumed. The following formula shall be used:’;
- (f)
under subsection 2.1.2(b), the following sentence is inserted at the end of the first paragraph: ‘Where relevant, carbonate content values shall be adjusted for the respective moisture and gangue content of the applied carbonate material, and take into account other magnesium bearing minerals than carbonates.’;
- (g)
‘Table 1: Stoichiometric ratios’ is replaced by the following:
‘
Carbonate Ratio[t CO2/t Ca-, Mg- or other Carbonate] Remarks CaCO3 0,44 MgCO3 0,522 general: XY(CO3)Z Emission factor = [MCO2 ]/{Y * [Mx] + Z * [MCO3 2- ]} X Mxalkali earth or alkali metal
MCO2molecular weight of X in [g/mol]
MCO3-molecular weight of CO2 = 44 [g/mol]
Ymolecular weight of CO3 2- = 60 [g/mol]
Zstoichiometric number of X
= 1 (for alkali earth metals)
= 2 (for alkali metals)
stoichiometric number of CO3 2- = 1
’
- (h)
under subsection 2.1.2, Calculation method B: Alkali Earth Oxides is replaced by the following: ‘CO2 emissions arise from the calcination of carbonates and shall be calculated based on the amounts of CaO and MgO contents in the lime, dolime or magnesia produced. Already calcined Ca and Mg entering the kiln, for instance through fly ash or fuels and raw materials with a relevant CaO or MgO content, as well as other magnesium bearing minerals than carbonates shall be considered appropriately by means of the conversion factor. Kiln dust leaving the kiln system shall be considered appropriately.’;
- (i)
‘Table 2: Stoichiometric ratios’ is replaced by the following:
‘
Oxide Stoichiometric ratios Remarks CaO 0,785 [tonne CO2 per tonne of oxide] MgO 1,092 [tonne CO2 per tonne of oxide] general: XY(O)Z Emission factor = [MCO2 ]/{Y * [Mx] + Z * [MO]} X Mxalkali earth or alkali metal
MCO2molecular weight of X in [g/mol]
MOmolecular weight of CO2 = 44 [g/mol]
Ymolecular weight of O = 16 [g/mol]
Zstoichiometric number of X
= 1 (for alkali earth metals)
= 2 (for alkali metals)
stoichiometric number of O = 1
