  • Conversion of acid gas to sulphate or phosphate-based fertilizers
    Patent number: 9187379
    Abstract: A method is disclosed for producing sulphate or phosphate-based fertilizer from hydrogen sulphide. The method involves feeding a stream containing a substantial volume of hydrogen sulphide and air to a furnace, where it is burned to produce a sulphur dioxide rich gas stream. The sulphur dioxide rich gas stream is then fed to a reactor to produce a sulphuric acid stream and a waste stream comprising carbon dioxide, nitrogen, oxygen, trace impurities and trace amounts of unreacted sulphur dioxide. The sulphuric acid stream is finally converted to a sulphate or phosphate-based fertilizer.
