Abstract (en)

[origin: WO2016012309A1] The present invention relates to a method for upgrading biogas and production of ammonium sulphate, comprising the steps of : condensing a biogas by contacting the biogas with cooling medium to produce biogas with a reduced water content; pressurizing the biogas with a reduced water content to a pressure of about 5 to 25 bar to produce pressurized biogas; leading the pressurized biogas over a molecular sieve to separate hydrogen sulfide and to produce pseudo gas; leading the separated hydrogen sulfide to an incinerator / quencher and heating the hydrogen sulfide to a temperature above 700°C and quenching the heated hydrogen sulfide with water to produce sulphuric acid; and bringing the sulphuric acid in contact with ammonia to produce ammonium sulphate.
