OXIDATIVE PROCESSES FOR SELF-HEATING AND PYROPHORIC CATALYSTS CONTAINING ACTIVE METAL SULFIDES, AND MITIGATION OF HALIDE AND POLYTHIONIC ACID STRESS CORROSION CRACKING MECHANISMS IN PROCESS EQUIPMENT
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.
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.

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.

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.
