Abstract:
Methods for making sulfide scavenging compositions are provided. The compositions are secondary amine-formaldehyde adduct (SAFA) scavengers comprising less than about 40 wt % N-methyl secondary amines therein. The methods include reacting secondary amines with formaldehyde. Methods for removing sulfides from fluid streams are also provided. The methods include adding secondary amine-formaldehyde adduct (SAFA) scavengers to fluid streams. SAFA scavengers comprising less than about 40 wt % N-methyl secondary amines of the total weight of SAFA scavengers are also disclosed.
