BVT-Merkblatt zu Abwasser- und Abgasbehandlung

Annexes
For new, large heating installations the provisions of section 5.43.2 apply, except for the emission
limit values included in the section. These are replaced by the emission limit values included
in appendix 5.20.2.
As a derogation from article 3.2.1.2, § 3, a), for existing establishments the more stringent
emission limit values apply as referred to in the third subsection, as of 1 January 2005.
§ 2. From 1 January 1994 the operating conditions in the operating licences for oil refineries
with respect to SO 2-, NO x-, CO and dust are replaced by the provisions of § 1.
§ 3. For the application of the provisions of § 1 of this article, the following specifications must
be respected:
1. for the definitions of flue gases and emission limit values, for new and existing heating installations
and for steam and gas turbine installations (STEG) the definitions of article 1.1.2
apply, in particular concerning industrial establishments which can cause air pollution.
For processing installations the actual flow rates in m 3 /hour must be converted at the normal
temperature (273 °K) and pressure (101.3 kPa), but on a dry basis as specified in article
4.4.3.1. with the actual quantity of excess oxygen
2. measuring strategy for suspended particulates, SO2 , NOx , CO, Ni and V:
- for heating installations, including machines with internal incineration the provisions of
article 5.43.2.3. apply, §§ 1 and 2
- for processing installations, residual gas measurements are constantly conducted or the
emissions are calculated on the basis of constant or periodically measured relevant parameters
according to codes of good practice as in article 5.43.2.3., §§ 1 and 2
3. assessment of measuring results:
for the assessment of the measuring results the following applies:
- for SO2: the provisions of article 5.43.2.4 with continuous measurement or article 4.4.4.5
with discontinuous measurement
- for NO x and CO: the provisions of article 5.43.5.1, § 4 with continuous measurement or
article 4.4.4.5 with discontinuous measurement
- for suspended particulates: the provisions in article 5.43.5.1, § 4 with continuous measurement
or article 4.4.4.5 with discontinuous measurement
- for Ni and V: the provisions as mentioned for NO x, in article 5.43.5.1, § 4 with continuous
measurement or article 4.4.4.5 with discontinuous measurement.
§ 4. Gaseous effluents discontinuously released by a processing such as gaseous effluents resulting
from the regeneration of catalytic agents and with inspection and cleaning activities
must be transported to a combustion facility or a torch, or equivalent measures must be taken to
ensure emission reduction.
Gaseous effluents released with the starting up or stoppage of an installation must, to the extent
possible, be transported to a collection system for gaseous effluent or incinerated in process
heating installations. When this not possible, the gases must be led to a torch, in which for organic
substances an emission level of 1 % with respect to the total carbon content may not be
exceeded.
Gaseous effluents from desulphurisation installations or other sources with a volume level of
hydrogen sulphide of over 0.4 % and a mass flow of hydrogen sulphide of over 2 tonnes/day
must be further processed.
Gaseous effluents which are not further processed must be transported to an incinerator.
As a derogation from the provisions of chapter 4.4, the emissions of hydrogen sulphide in the
discharged gaseous effluent may not exceed 10 mg/Nm 3 .
Hydrogen sulphide-containing water may only be processed in such a way that the release of
gaseous effluent into the atmosphere is avoided.
With the transfer of base, intermediary and finished products the emissions of organic substances
with a vapour pressure of over 13.3 kPa at a temperature of 35 °C must be reduced by
means of appropriate measures, such as by gas pendulum, extraction and transfer to an effluent
gas purification installation.
