Abstract

Problem statement: For purification of smoke in PPHU Duda-Bis Plant water washers, placed in the outlet channel of smoke chamber, have been applied, but the amount of the substances remaining in the air after passing through the washer were not acceptable by the standards and caused repulsive odor emitted into the atmosphere. Approach: To eliminate discomfort, caused by smoke emission unto the environment, PPHU Duda-Bis has been introduced a simple and effective method of thermal utilization of post-curing smoke by using heated with natural gas boiler. Before the smoke enters the boiler, water vapors undergo condensation and the water drops obtained are separated in steam drier. The smoke introduced into the boiler brings some excess of air. Results: After the new method of curing smoke after-burning had been put into practice in PPHU Duda-Bis, the unpleasant odorous and harmful to the environment compounds were eliminated. The content of the emitted components per year, after thermal utilization of the smoke, was 100 times lower in comparison to the wet-method. Conclusion: The thermal methods belong to the most efficient BAT techniques enabling removal of the unpleasant odorous substances from the gases generated by meat industry.
