摘要： Pyrophoric material such as iron sulfide is frequently found in refinery equipment. When the equipment is opened to the atmosphere for maintenance, an exothermic reaction can take place that may cause injury to personnel and catastrophic damage to equipment. A process used to treat pyrophoric material uses sodium nitrite injected into a gaseous carrier stream to oxidize iron sulfides to elemental sulfur and iron oxides. The sodium nitrite solution may be buffered to a pH of about 9 with disodium phosphate or monosodium phosphate. A chemical additive that provides a quantitative measure of reaction completion may be added to the treatment solution.

摘要： Certain fatty acid amide-based surfactants such as cocamide DEA (also known as “coco(nut) diethanolamide” or “coco(nut) DEA”) when dissolved or dispersed in a cutting oil (diesel, light cycle oil, naphtha, and such other petroleum distillates) produce a petroleum distillate having significantly enhanced solvency for heavy residuals. Such solutions or dispersions are especially useful for cleaning vessels and similar equipment in refineries by circulating the solution or dispersion in the vessel, optionally with the application of heat.

摘要： Disclosed is an improved process for removing heavy oil, bitumen and/or paraffinic materials in oil production or storage wells including onshore and offshore petroleum wells, petroleum residual disposal wells and Steam Assisted Gravity Drainage (SAGD) or Cyclic Steam Stimulation (CSS) producing wells used in the oil sands industry. This process helps restore the operating efficiency of organically contaminated hydrocarbon producing wells in a safe, fast and effective manner without the need to insert any equipment to mechanically remove organic contaminants. Used is a heated terpene-based chemical injected with or without steam following a hot water or steam pre-heat to create a very effective cleaning process.

摘要： Disclosed is a novel process for interior cleaning and by cleaning, removing noxious gas and/or restoring the operating efficiency of organically contaminated hydrocarbon processing equipment in a safe and effective manner and in a very short period of time, without a need to manually enter an unsafe environment and mechanically remove organic contaminants. Used is a formulation of non-aqueous, monocyclic saturated terpene mixed with a non-ionic surfactant package. The terpene-based chemical is injected into organically contaminated equipment using a novel process involving high-pressure steam to form a very effective cleaning vapor.

摘要： Disclosed is a novel process for cleaning and restoring the operating efficiency of organic liquid chemical exchangers in a safe and effective manner and in a very short period of time, without a need to disassemble the equipment and without the need to rinse contaminate from the equipment after cleaning. Used is a formulation of monocyclic saturated terpene mixed with a non-ionic surfactant package specifically suited to oil rinsing. The terpene-based chemical is injected into organically contaminated exchangers using a novel process involving high-pressure steam to form a very effective cleaning vapor.

摘要： A unit and system are operable with cooling fluid for handling effluent produced in a cleaning process of refinery equipment. A drum of the unit has an inlet for the effluent, a liquid outlet for condensed effluent, and a vapor outlet for uncondensed effluent. A shell disposed in an interior of the drum and has a passage communicating outside the drum. A heat exchanger is disposed in the passage of the shell. As the effluent from the inlet enters the shell’s passage at the distal end of the shell, the heat exchanger cools the effluent using cooling fluid cycled through the heat exchanger. Condensed effluent escaping from the shell can fill the drum’s interior up to a liquid level. Uncondensed effluent escaping from the shell can collect in the open space of the drum, being subject to further condensation.

摘要： Methods and compositions for the removal of metal sulfides from spent catalysts in reactor vessels and associated equipment are described herein. Using the methods described herein, metal sulfides of a spent catalysts are converted to metal oxides and gaseous and liquid by-products when reacted with a formulation having one or more oxidizing agents. Also, using the methods described herein, metal sulfides and sulfides in the process equipment are oxidized, eliminating the potential formation of polythionic and thionic acids protecting materials from polythionic stress corrosion cracking. Also, using the methods described herein, halides (including chloride) and halide containing compounds and salts in the process equipment are removed, eliminating the potential formation of halide acids and further neutralized via pH buffering, and protecting materials from halide stress corrosion cracking.

摘要： A hose conducts high-temperature steam combined with cleaning solution in a cleaning operation. The hose comprises an external liner, an intermediate conduit, and an internal liner. The external liner comprises first braiding and is disposed along a longitudinal length of the hose. The intermediate conduit is disposed in the external liner along the longitudinal length of the hose. The intermediate conduit has a plurality of corrugations disposed laterally in the tubular wall of the intermediate conduit. The internal liner comprises second braiding and is disposed in the intermediate conduit along the longitudinal length of the hose. The internal liner provided a full bore for the hose configured to conduct the high temperature steam combined with the cleaning solution in a volatilized mixture.
