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 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. and wherein said catalyst comprises an alkali hydroxide base, said sulfide scavenger comprising an inerts member present therein, said inerts member comprising at least one member selected from the group…
