How can reduce SO2 from chemny?

Answer 1

Factories that produce SO2 as a waste gass from their manufacturing processes usually pass the gass through a 'scrubber' before releasing it out of the chimney. The scrubber is a piece of equipment containing chemicals, that the gas bubbles through. The chemicals combine with the gasses, turning them into less harmful substances. For example, the Oxygen and Sulphur atoms can be separatedfrom each other. The Sulphur can be re-used either on its own - or combined with other chemicals for reprocessing. The Oxygen can also be re-processed.
