Abstract
Methods for making sulfide scavenging compositions are provided. The method comprises reacting at least one secondary amine with at least one aldehyde and solvent in the presence of a catalyst to form a reaction composition, wherein a reaction temperature is less than or equal to 90° C. Sulfide scavengers using the above method are also disclosed. Methods for removing sulfides from fluid streams are also provided. The methods include adding the above sulfide scavengers to fluid streams.
Claims37
A method for making a sulfide scavenger comprising reacting at least one secondary amine with at least one aldehyde and solvent in the presence of a catalyst to form a reaction composition, wherein a reaction temperature is less than or equal to 90° C.
A sulfide scavenger prepared by a method comprising reacting at least one secondary amine with at least one aldehyde and solvent in the presence of a catalyst to form a reaction composition, wherein a reaction temperature is less than or equal to about 90° C.
A method for reducing sulfides from a fluid stream, said method comprising contacting said fluid stream with a sulfide scavenger, wherein said sulfide scavenger was prepared by a method comprising reacting at least one secondary amine with at least one aldehyde and solvent in the presence of a catalyst to form a reaction composition, wherein a reaction temperature is less than or equal to about 90° C.
