ABSTRACT:
Hydrogen sulphide and ammonia are removed from gaseous streams comprising these compounds by combustion of ammonia into nitrogen and water vapor and partial combustion of hydrogen sulphide into sulphur dioxide, whereby hydrogen sulphide reacts with the sulphur dioxide formed in a molar ratio of 2:1 under formation of elementary sulphur and water, by mixing all gases which are to be combusted before causing them to enter at least one burner. Preferably the combustion air required for the ammonia containing gas stream and the combustion air required for the hydrogen sulphide rich gas stream are controlled separately, after which both air streams are united.
