Decontamination of sulfur contaminants from a vessel
A method for treating sulfur contaminants is provided. The method comprises introducing a methylmorpholine-N-oxide solution to a vessel, wherein the vessel comprises a water layer and a gas layer, wherein the water layer and the gas layer comprise the hydrogen sulfide; introducing methylmorpholine-N-oxide into the water layer; and treating the water layer by allowing the methylmorpholine-N-oxide to react with the hydrogen sulfide.
1. A method for removing hydrogen sulfide, comprising:
(A) introducing a methylmorpholine-N-oxide solution to a vessel, wherein the vessel comprises a water layer and a gas layer, wherein the water layer and the gas layer comprise the hydrogen sulfide;
(B) introducing methylmorpholine-N-oxide into the gas layer;
(C) introducing steam to the vessel, wherein steam removes at least a portion of the hydrogen sulfide from the water layer;
(D) allowing the steam comprising at least a portion of hydrogen sulfide from the water layer to evaporate into the gas layer;
(E) adjusting a hydrogen sulfide rate of evaporation by increasing the vessel temperature;
(F) treating the gas layer by allowing the methylmorpholine-N-oxide to react with the hydrogen sulfide; and
(G) treating the water layer by reducing a temperature of the gas layer to a temperature below the boiling point of methylmorpholine-N-oxide thereby allowing the methylemorpholine-N-oxide to condense into the water layer.
2. The method of claim 1 , further comprising allowing the hydrogen sulfide in the water layer to react with the methylmorpholine-N-oxide.
3. The method of claim 1 , wherein the treating the water layer comprises converting the hydrogen sulfide to elemental sulfur.
4. The method of claim 3 , wherein the elemental sulfur is removed from the vessel.
