BVT-Merkblatt zu Abwasser- und Abgasbehandlung

Annexes
These ordinances are based on the Austrian “Wasserrechtsgesetz” (Water Right Act) (BGBl. I
155/1999). Special ordinances that are of interest for plants producing organic chemicals are:
� Verordnung über die Begrenzung von Abwasseremissionen aus der Herstellung von Kohlenwasserstoffen
und organischen Grundchemikalien BGBl. II 1999/7 (Ordinance for the
limitation of waste water emissions from the production of hydrocarbons and basic organic
chemicals)
� Verordnung über die Begrenzung von Abwasseremissionen aus der Erdölverarbeitung
BGBl. II 1997/344 (Ordinance for the limitation of waste water emissions from oil refining)
� Verordnung über die Begrenzung von Abwasseremissionen aus der Herstellung von technischen
Gasen BGBl. 1996/670 (Ordinance for the limitation of waste water emissions from
the production of industrial gases)
� Verordnung über die Begrenzung von Abwasseremissionen aus der Herstellung von anorganischen
Düngemitteln sowie von Phosphorsäure und deren Salzen BGBl. 1996/669 (Ordinance
for the limitation of waste water emissions from the production of inorganic fertilizers
or phosphoric acid and its salts).
­ Hydrocarbons and basic organic chemicals
The ordinance for the limitation of waste water emissions from the production of hydrocarbons
and basic organic chemicals regulates the emission standards for the production of
hydrocarbons and basic organic chemicals. This ordinance entered into force at the
13.1.2000. Plants, which have been approved before this date have to fulfil these requirements
within the next six years. This ordinance regulates:
i. storage of products from the processing of crude oil or crude oil fractions, which are
used in the production processes of item ii to vi
ii. production of alkenes, alkines or aromatics from processing products of crude oil or
crude oil fractions with cracking, using additional steam (steam cracking)
iii. production of chemically pure hydrocarbons or their mixtures from cracking products
of item ii by using physical separation processes
iv. production of basic organic chemicals from products of item ii or iii using alkylation,
desalkylation, dehydrogenation, disproportionation, hydration, hydroxylation, hydrodesalkylation,
hydrogenation, isomerization, oxidation or etherification
v. production of nitrogen containing basic organic chemicals from hydrocarbons of
item ii or iii or from substances of item iv (e. g. amides, amines, cyanates, isocyanates,
lactams, nitriles, nitro-, nitroso or nitrate compounds, nitrogen containing aromatics)
vi. production of sulphur or phosphorus containing basic organic chemicals from hydrocarbons
of item ii or iii or from substances of item iv
vii. production of halogenated basic organic chemicals from hydrocarbons of item ii or
iii or from substances of item iv
viii. storage of products from item ii to vii
ix. cleaning of drawing-off air and aqueous condensates from actions according to item
to viii
x. cleaning of combustion gases from actions according to item i to viii with the use of
aqueous substances if simultaneously physical or chemical reactions with the aim of a
synthesis or production are made or if the exhaust gas of the combustion is mixed with
an other waste gas and the composition of the residual exhaust gas is significantly different
compared to the composition of the combustion gas.
