Process and device for purifying fermentation gases

摘要

The system to clean foul-smelling gas emissions, has a gas scrubber (3) to take the raw gas (1). Before the gas enters the scrubber, silicon compounds are converted by a catalyst (2) containing treated active carbon into low molecule silicon compounds. The scrubber uses a polar solvent, e.g. cold water. The cleaned gas is passed through a number of active carbon filters (4).
