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： A method for removing elemental sulfur from a hot gas stream, such as an autoclave vent gas, while simultaneously cooling the gas stream. The method results in conversion of sulfur in the hot gas stream to the form of solid, non-sticky sulfur allotropes such as rhombic sulfur while avoiding formation of sticky sulfur allotropes such as monoclinic sulfur, thereby avoiding scaling and fouling of plant equipment. According the method, the hot gas stream is contacted with an aqueous medium containing a particulate material inside a quench vessel having a first inlet for the hot gas stream, a second inlet for the aqueous medium, and an outlet for removing a sulfur-containing liquid fraction from the vessel. At least a portion of the sulfur contained in the hot gas stream, along with other condensable materials, becomes incorporated into the aqueous medium and is subsequently drained from the vessel. The aqueous medium may comprise a slurry of tailings or other waste material, and the particulate matter contained in the aqueous medium may provide nucleation sites for the preferential formation of non-sticky solid forms of sulfur.

摘要： A method of carrying out a chemical reaction in a fluidized bed reactor is provided wherein the reactants include at least one finely sub-divided reactant having a particle size substantially smaller than that of the particles constituting the fluidized bed. The reactor includes a downcomer compartment and a riser compartment operated such that the fluidized bed particles circulate by moving down the downcomer compartment and up the riser compartment. The finely divided solid reactant is introduced, either as such, or in an agglomerated form, into the central or upper region of the fluidized bed in the downcomer compartment such that it becomes entrained in the downwardly moving fluidized bed in the downcomer compartment and moves countercurrent to the fluidizing gas towards the lower end of the riser compartment. The reaction products which may be, or include, fine divided solids are carried out of the top of the reactor from the riser compartment. The fluidized bed particles comprise electrically conductive particles which are heated by passing an electrical current therethrough. Other reactants, which may be solid or gaseous, can be added through the same or other inlets, or may be embodied in the fluidizing gas.
