ABSTRACT:
Nitrogen and sulfur contaminants are removed from an aqueous stream containing the same by steam stripping the aqueous stream to produce a first vapor stream, containing water and a major portion of NH.sub.3 and H.sub.2 S, reducing the temperature of the first vapor stream to a temperature at which a substantial portion of H.sub.2 S is insoluble in water to produce a second vapor stream, containing a major portion of the H.sub.2 S, and a second liquid stream, containing a major portion of the NH.sub.3, and separating the second vapor and liquid streams. The second liquid stream is added to a fluid containing acidic materials to reduce corrosion and the formation of solid deposits. Preferably, the aqueous stream is obtained from refinery operations and the fluid containing acidic materials is the overhead of a crude oil fractional distillation step.
