= Claus process
Created by the german chemist Carl Friedrich Claus, it makes it possible to convert hydrogen sulfide (from natural gas) to elemental sulfur.
The overall reaction can be descibed as follows:
$$
2H_2S + SO_2 \rightarrow 3S + 2H_20
$$
The Claus' process served as a better replacement of the Frasch process, which obtained elemental sulfur from naturally found deposits underground.
