Abstract:
Methods for reducing sulfides from fluid streams are provided. The methods comprise adding secondary amine-formaldehyde adduct (SAFA) scavengers to fluid streams. The SAFA scavengers added comprise less than about 40 wt % N-methyl secondary amines of the total weight of SAFA scavengers. Methods for distilling N-methyl secondary amines from secondary amine-formaldehyde adduct (SAFA) scavengers are also provided. Purified SAFA scavengers are also disclosed.
