CONTENT

Specific details of the UNFCCC -NAI Software use to calculate GHG emissions in the sector Industrial Processes.

Practical exercises (to be solved by the participants after the presentation).

BACKGROUND

The choice of a good practice method is given by the decision threes in the IPCC GPG according to national circumstances.

The UNFCCC –NAI Software contains, basically, the methods of smaller complexity that can use countries for the preparation of inventories.

However, in principle, the software can be used to report the estimated emissions independently of the complexity of used method (Tier 2, 3 etc).

-The default emission factors in the IPCC Guidelines correspond to 100% of CaO (or CaO.MgO) in lime and can lead to an overestimation of emissions since the CaO and MgO content may less than 100%. Suggestion: Calculate EF outside the software using stoichiometric ratios and CaO (CaO.MgO) content by lime type (or use default values for calculating EF). After having obtained the EF, emissions can be calculated directly in the software

Limestone and Dolomite Use

2-3s1 Estimate quantity of limestone or dolomite used. Adjust the default EF using the fractional purity (f) of limestone in CaCO3.

-Good practice guidance has not yet been developed. After having obtained the EF, emissions can be calculated directly in the software. -Consumption is assumed to equal material mined plus material imported minus material exported. Alert: Exclude of calculation limestone or dolomite used for producing cement, lime and magnesium, agricultural activities and processes where CO2 is not generated.

Soda Ash Production and Use

2-4s1(production) 2-4s2 (use)

-Good practice guidance has not yet been developed. If activity data are available there are not difficulties to obtain the emissions with the software. Alert: CO2 emissions associated with the use of coke in soda ash production should be accounted for separately and subtracted from the totals in the combustion section. -For most of the major uses, it is assumed that for each mole of soda ash used, one mole of CO2 is emitted.

Nationally compiled production data may be used, when plant specific data are not available. -The worksheet of the software doesn't facilitate to subtract the N2O destruction. Suggestions: 1) Make the calculation outside of software; incorporates the results manually in the Sectoral Table and the Tables of Summary of the Inventory; add note in the documentation box of the Tables 2-7s1 and 2-8s1 clarifying the used method and results obtained. -If there is not abatement technologies implemented, uses the software directly to estimate the emissions of N2O, NOx, NMVOC and CO.

MAIN CATEGORIES

Tier 1: Worksheets

Tier 2 Methods Remarks

-Iron and Steel 2-11s1 (CO2). The Tier 1 calculates emissions from the consumption of the reducing agent and using EF similar to those used to estimate combustion emissions.

2-11s3 (NOx, NMVOCs, CO and SO2

The Tier 2 method includes a correction for the carbon stored in the metals produced. With this method, emissions from iron production and steel production are calculated separately.

CO2 -If activity data are available there are not many difficulties to obtain the CO2 emissions with the software (both using Tier 1 and Tier 2 method). Suggestions: -To estimate the emissions separated from iron and steel and obtain the total of emissions carry out the calculations outside the software and incorporate the results manually to the Sectoral and Summary Tables. For steel produced in electric arc furnaces also add the carbon released from consumed electrodes. -Lime added to electric arc furnaces and its CO2 emissions should be accounted on the lime use section. -When biomass carbon is used the emissions should be reported in the land-use change and forestry sector. Alert: The estimation of CO2 emissions based on production data and production base EF (Worksheet 2-11s2) is not considered to be good practice. Non-CO2 gases If activity data are available there are not difficulties to obtain the emissions with the software.
