To meet the emission limits, four out of five successively measured values have to be lower than the emission limit
value and only one measured value may exceed the emission limit (maximum 50 % of the emission limit). The majority
of the parameters have to be determined with mass proportional homogeneous daily average samples. The parameters
temperature, TSS, pH, cyanide, sulphide, POX and sum of volatile aromatics (BTXE) are determined with random
samples.
For the production of acetylene with calcium carbide as raw material emission limits are set in
the ordinance “Verordnung über die Begrenzung von Abwasseremissionen aus der Herstellung
von technischen Gasen” (BGBl. 1996/670). All acetylene plants in Austria use calcium carbide
processes for acetylene production
