Abstract
The invention relates to a method for the prevention and removal of H2S and/or other sulfhydryl compounds and iron sulfide deposits from gas and/or liquid streams in industrial process systems. Formulations comprising aldehydes, aldehyde donors, and/or aldehyde stabilizers, excluding triazines, in combination with the reaction product of an amino acid and a hydroxymethylphosphine or hydroxymethylphos-phonium salt, and optionally a quaternary ammonium compound and/or one or more N-hydrogen compounds such as 5,5-dialkylhydantoin or amines, are rapidly and sustainedly scavenging H2S originating from process and/or microbial sources. The formulations possess high capacities for H2S removal and are relatively pH-insensitive.
