ANNEX IVU.K. Activity-specific monitoring methodologies related to installations (Article 20(2))

1. Specific monitoring rules for emissions from combustion processes U.K.

C. Flue gas scrubbing U.K.

Process CO2 emissions from the use of carbonate for acid gas scrubbing from the flue gas stream shall be calculated in accordance with Article 24(2) on the basis of carbonate consumed, Method A as follows, or gypsum produced, Method B as follows.

Method A: Emission factor U.K.
Tier 1

:

The emission factor shall be determined from stoichiometric ratios as laid down in section 2 of Annex VI. The determination of the amount of CaCO3 and MgCO3 in the relevant input material shall be carried out using best industry practice guidelines.

Method B: Emission factor U.K.
Tier 1

:

The emission factor shall be the stoichiometric ratio of dry gypsum (CaSO4 × 2H2O) to CO2 emitted: 0,2558 t CO2/t gypsum.
