Abstract

The invention relates to a method for selectively removing sulphur and/or sulphur containing contaminant compounds from a gas flow, which also comprises CO2, said method comprising the steps of: placing the gas flow into contact with a preselected metal ion at a pH lying in the range of between about -0.05 and about 7.0, wherein the metal ion and the contaminants react together in order to form a solid metal salt of the contaminants which precipitates out of the gas flow, wherein the lower pH limit of about -0.05 substantially ensures that the metal salt formed between the metal ion and the contaminants substantially exclusively is precipitated out of the gas flow, and wherein the upper pH limit substantially ensures that CO2 is not precipitated out of the gas flow as a metal carbonate salt.
