Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 1. A method for making a sulfide scavenger comprising reacting at least one secondary amine with at least one aldehyde in the presence of a catalyst to form a reaction composition, wherein a reaction temperature is less than or equal to 90° C., wherein said catalyst comprises a base, said base comprising an alkali hydroxide. 2. The method as recited in claim 1 wherein inerts are formed, said sulfide scavenger comprising less than about 5 wt…
