Fremgangsmåde til fjernelse af hydrogensulfid og/eller carbondisulfid fra afgasser

The invention relates to a process for eliminating hydrogen sulphide (H2S) and/or carbon disulphide (CS2) from exhaust gases. These exhaust gases are contacted with water and bromine, so that H2SO4 and HBr in aqueous solution and, possibly, CO2 are formed. Bromine is recovered from the hydrobromic a...

Zusammenfassung:	The invention relates to a process for eliminating hydrogen sulphide (H2S) and/or carbon disulphide (CS2) from exhaust gases. These exhaust gases are contacted with water and bromine, so that H2SO4 and HBr in aqueous solution and, possibly, CO2 are formed. Bromine is recovered from the hydrobromic acid in an electrolysis cell. Saleable hydrogen is also produced.
