Expert Answer:

If not treated sulphur dioxide can contribute to acid rain so in order to protect the environment it is necessary to capture the sulphur dioxide and convert it to a marketable product or to an inert solid waste which can be safely stored.
The most common conversion treatment is to produce sulphuric acid. However, depending on the economics and concentration of the sulphur dioxide gas, other products include elemental sulphur, liquid sulphur dioxide, ammonium sulphate and gypsum
