5 AX-CONSULTING 4 1. Introduction The aim of the Odorless Casting project is to address the problems related to the air pollution control of odorous and hazardous gaseous emissions from foundry processes and to pilot specifed abatement technologies of the emissions. in Finland is one of the seven pilot foundries in the project where the odour emission balance will be determined. At steel foundry in total 5 emission points were measured and analyzed. The selected measurement points are presented in APPENDIX 9. Measurements were carried out on Measurement results Measurement results are presented in APPENDICES Conclusions The highest odour emissions (ou E /h) at steel foundry were measured at the heavy moulding and pouring (general exhaust, PK311) and at the manganese moulding and pouring (general exhaust, MP12). The total odour emissions at steel foundry were ou E /h. The total odour emissions in 2012 was ou E /h/produced ton. 4. Production during measurements The production was normal during the measurement period. On the production rate of the foundry was about 67 t/day, and the annual production in 2012 was about t/a. 5. Measurement staff The measurement was carried out by Mr. Marko Liikanen and Mr. Heikki Paukkunen from AX-LVI Consulting Ltd.

6 AX-CONSULTING 5 6. Procedure 6.1 Odour The odour samples were taken in sample bags from the exhaust air during the normal operation of the process. The sample points of emission flows were chosen to represent the average odour of the area or process in question. The odour samples were taken in accordance with the EN 13725:2003 standard. The strength of the odour determined by an odour panel and dynamic olfactometric analyses according to standard EN 13725:2003. In the method, the odour concentrations ou E /m³ (ou=odour unit) were measured by the dilution of the odour sample to the odour threshold where the numerical value of the odour concentration is equal to the dilution factor that is necessary to reach the odour threshold. The odour panel comprises 4 persons from AX-LVI Consulting Ltd. The suitability of personnel who participated in the odour panel had been determined according to standard practice using n-butanol. The odour emissions of the foundry were calculated based on the determined odour concentrations and airflow of the area or process in question. 6.2 TVOC (Total Volatile Organic Compounds) TVOC concentrations (methane equivalent concentration, ppm) were measured continuously with flame ionization detector analyzer (FID). The FID analyzer calibrated during the measurements with zero and span gases. The FID measurements carried out in accordance with the USA Environmental Protection Agency (EPA) Method 25. The analysers results were double-checked and concentration response was calculated for the devices by taking samples from measured gases simultaneously into adsorption tubes via a condenser and analysing different hydrocarbon compounds from the condensate as well as adsorption tube by gas chromatography. The samples were used to derive multiplying factors to make the methane equivalent response (ppm) of the analysers reflect the real VOC concentration (mg/nm 3 ). Standards SFS 3869 and SFS 3861 were applied in adsorption tube measurement. 6.3 Hydrocarbons and BTEXN (Benzene, Toluene, Ethylbenzene, Xylene, Naphthalene) Hydrocarbon and BTEXN compounds were measured from the samples taken into an activated charcoal sample tube from the exhaust air with a pump. The measurements was carried out in accordance with the SFS 3869 standard.
