Definitions

  • This invention relates to methods and compositions for reacting with sulfides, and more particularly, to effectively remove sulfur impurities with amine-based H 2 S scavengers and simultaneously scavenge the resulting amines in situ.
  • Hydrogen sulfide is a clear toxic gas with a foul odor. It is also highly flammable. The Environmental Protection Agency and other regulatory agencies worldwide strictly control the release of hydrogen sulfide into the environment. Hydrogen sulfide is often present in well water, waste water, and other aqueous streams. Hydrogen sulfide may also be present in crude oil and natural gas reserves and must be removedbefore using.
  • Sulfur in the form of sulfides, thiols and mercaptans in crudes
  • Crudes with high degrees of sulfur content are classifies as sour crudes. These sour crudes command a lower price than low sulfur (sweet) crudes.
  • One method that refiners use to remove the sulfur in sour crudes is by adding hexahydrotriazines to the crudes to scavenge sulfur compounds. Hexahydrotriazines are formed by the reaction of aldehydes (especially formaldehyde or a formaldehyde precursor) with amines.
  • this method While effective in removing sulfur compounds, this method then generates primary amines, such as monoethanol amine (MEA) , methylamine, methoxy propyl amine, etc., in the crude oil. These amines in the crude oil then represent another problem for the refiners as they contribute to corrosion and fouling in the refinery equipment. When present in crude these detrimental amines are referred to as “tramp amines” .
  • Other sources of tramp amines in crudes include naturally occurring amines in the crude reservoirs. Tramp amines have been found causing scaling, corrosion, and other detrimental effects.
