New process turns coal emissions into sulfuric acid, saving water and energy.
The article discusses a method to clean up the emissions from burning high-sulphur coal by using a special solution and turning the sulphur dioxide into sulphuric acid. By combining different processes, the researchers found a way to save water and produce more steam as a by-product. They recommend starting with a certain concentration of sulphur dioxide and using a specific system to maximize efficiency and minimize costs.
