Abstract:
A method and composition for removing contaminant material from industrial equipment are disclosed herein. The method includes providing a solvent composition having methyl soyate, an aprotic solvent such as dimethyl sulfoxide, an additional solvent, and a cationic surfactant. The method also includes contacting the contaminant material with the solvent composition and allowing the solvent composition to react with the contaminant material such that at least a portion of the contaminant material is no longer attached to the industrial equipment.
Abstract:
A method of equipment decontamination may include: introducing a cleaning stream comprising hydrogen and a solvent comprising a fatty acid methyl ester and an oxygenated solvent, or alternatively comprising a carrier fluid and a hydrocarbon solvent, into the equipment; and introducing a stream comprising nitrogen into the equipment, wherein the equipment comprises deposits and other contaminants.
Abstract:
A method and composition for removing contaminant material from industrial equipment are disclosed herein. The method includes providing a solvent composition having methyl soyate, N- methylpyrrolidinone , an additional solvent, and a cationic surfactant. The method also includes contacting the contaminant material with the solvent composition and allowing the solvent composition to react with the contaminant material such that at least a portion of the contaminant material is no longer attached to the industrial equipment.
Abstract:
A method for decontaminating industrial facility equipment while the equipment remains in operation (i.e., on-line decontamination). In one embodiment, the method comprises reducing the total volumetric flowrate, injecting a decontamination composition into the industrial equipment at an injection point while the industrial equipment remains in operation, wherein the decontamination composition comprises a solvent composition and a carrier fluid, allowing the decontamination composition to come in contact with any contaminant material disposed on the industrial equipment, wherein the contact removes the contaminant material from the industrial equipment, and managing the contaminant material removed from the industrial equipment.
Abstract:
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.
Abstract:
A method and system treat contaminated water, in one embodiment, the method comprises treating contaminated water by introducing a methylmorphoiine-N-oxide solution to a vessel. The vessel contains the contaminated water and iron oxide. The contaminated water comprises contaminants, in addition, the methyltnorpholine-N-oxide solution comprises methylmoipholine-N-oxide and water. The method further comprises contacting the methylmorpholine-N-oxide solution with the contaminated water. In addition, the method comprises treating the contaminated water by allowing the roethylmorphoiine-N-oxide to react with the contaminants in the presence of the iron oxide.
