Annex V — Emission and sulphur content limit values Protocol bij het Verdrag van 1979 betreffende grensoverschrijdende luchtverontreiniging over lange afstand inzake de verdergaande vermindering van zwavelemissies
Emission and sulphur content limit values
A. Emission limit values for major stationary combustion sources a/
(i) (MWth) | (ii) Emission limit value (mg SO2/Nm3 b) | (iii) Desulphurization rate (%)
1. Solid fuels (based on 6% oxygen in flue gas) | 50-100 | 2000
100-500 | 2000-400 (lineair decrease) | 40 (for 100-167 MWth) 40-90 (linear increase for 167-500 MWth)
>500 | 400 | 90
2. Liquid fuels (based on 3% oxygen in flue gas) | 50-300 | 1 700
300-500 | 1 700-400 (linear decrease) | 90
>500 | 400 | 90
3. Gaseous fuels (based on 3% oxygen in flue gas)
Gaseous fuels in general | | 35
Liquefied gas | | 5
Low calorific gases from gasification of refinery residues, coke oven gas, blastfurnace gas | | 800
B. Gas oil | Sulphur content (%)
Diesel for on-road vehicles | 0.05
Other types | 0.2
a) As guidance, for a plant with a multi-fuel firing unit involving the simultaneous use of two or more types of fuels, the competent authorities shall set emission limit values taking into account the emission limit values from column (ii) relevant for each individual fuel the rate of thermal input delivered by each fuel and, for refineries, the relevant specific characteristics of the plant. For refineries, such a combined limit value shall under no circumstances exceed 1700 mg SO2/NM3.
In particular, the limit values shall not apply to the following plants:
- Plants in which the products of combustion are used for direct heating, drying, or any other treatment of objects or materials, e.g. reheating furnaces, furnaces for heat treatment;
- Post-combustion plants, i.e. any technical apparatus designed to purify the waste gases by combustion which is not operated as an independent combustion plant;
- Facilities for the regeneration of catalytic cracking catalysts;
- Facilities for the conversion of hydrogen sulphide into sulphur;
- Reactors used in the chemical industry;
- Coke battery furnaces;
- Cowpers;
- Waste incinerators;
- Plants powered by diesel, petrol and gas engines or by gas turbines, irrespective of the fuel used.
In a case where a Party, due to the high sulphur content of indigenous solid or liquid fuels, cannot meet the emission limit values set forth in column (ii), it may apply the desulphurization rates set forth in column (iii) or a maximum limit value of 800 mg S02/Nm3 (although preferably not more than 650 mg SO2/Nm3.
The Party shall report any such application to the Implementation Committee in the calendar year n which it is made.
Where two or more separate new plants are installed in such a way that, taking technical and economic factors into account, their waste gases could, in the judgement of the competent authorities, be discharged through a common stack, the combination formed by such plants is to be regarded as a single unit.
b) mg SO 2 /Nm3is defined at a temperature of 273°K and a pressure of 101.3 kPa, after correction for the water vapour content.
