| Abstract |
When condensing sulfuric acid from gases containing sulfuric acid vapour and steam in excess, e.g. originating from a power station, a substantial decrease of the amount minute droplets of sulfuric acid ( the socalled acid mist) escaping to the surroundings is obtained, even in cases where the sulfuric acid plant is equipped into the gas in an amount of 10 to 12 solid particles per NM3 per 0.1% h2so4 vapour in the gas. The nucleation cores may, e.g., be generated by combusting hydrocarbons with >2 carbon atoms or silicones, or silicones, or added as smoke from an electric are or welding. |
