A method for cleaning a storage tank to which sodium metal is adherent, the method containing: filling, with an inert oil, the storage tank to which sodium metal is adherent; subsequently adding water, water vapor, or a humidified inert gas to the inert oil; providing a gas discharge line to the storage tank and measuring the hydrogen gas concentration in the gas discharge line; regulating the amount of the water, water vapor, or humidified inert gas to be added per hour in accordance with the level of the hydrogen gas concentration; regulating the temperature of the inert oil to 0-98°C; and converting the sodium metal into caustic soda while changing the liquid surface level of the inert oil in parallel with addition of the water, water vapor, or humidified inert gas to the inert oil.

A method for processing ore using carbonates so as to minimize the production of acidic wastes. The method includes adding the carbonates to the ore and after the carbonates have been added to the ore, substantially jointly grinding the ore and the carbonates to produce a treated ore mixture. Substantially jointly grinding the ore and the carbonates substantially mixes and homogenizes the ore and the carbonates so that acids subsequently created within the treated ore mixture are substantially neutralized within the treated ore mixture by the carbonates.

The invention concerns a method for treating household refuse or industrial waste incinerator ash, whereby the wastes are classified in two different size distribution phases, the solid phases filtered during such treatments are then subjected to a hydromatallurgical treatment which consists in a carbonatation step and a lixiviation step to extract the polluting elements. Optionally the solid load is then thermally treated by proportioning the fine and gross fractions to obtain an adapted silica/lime and silica/sodium ratio.

The invention concerns a method for treating residues derived from garbage and/or industrial waste incineration fumes comprising the following steps: A: desalting (1, 1') the residues by washing with sodium carbonate (2) in sufficient amount or slightly in excess to solubilize all the salts including the sulphates and precipitate the soluble calcium, the pH being higher than 11, then carrying out a solid/liquid separation to obtain a desalinised cake (3); B: lixiviating said cake (3) resulting from step A with sodium carbonate in sufficient amount or slightly in excess to obtain by reaction with the lime present in the cake or added thereto if necessary, the alkalinity required for solubilizing amphoteric metals, the pH being higher than 12, obtaining by solid/liquid separation a cake (6) and a supernatant (7) which is neutralised with carbon dioxide (8) and filtering the recuperated solution to obtain metal hydroxide sludge (11) and an aqueous sodium carbonate solution (14) which can be recirculated towards step B itself, and C: neutralising at a pH between 6.5 and 8.5, the residues (6, 6') resulting from step B.

153 Method for separating compounds in process streams EP95303850 1995-06-06 EP0686614A3 1998-07-29 HOFFMAN WILLIAM CHRISTOPHER; DEVER JOHN PATRICK
A method, especially applicable on a continuous basis to commercial process streams, for treating unwanted by-products and/or impurities contained in those streams. The method comprises the reaction in situ of such by-products or impurities with a reagent, preferably selected for its reactivity under ambient conditions of the process stream, to produce one or more materials which may then be separated from the process by economical means. The treated stream may be recycled to the process for further processing. While the method is not limited as to the process to which it is applied nor to the reagent or reagents used, in one convenient embodiment, formaldehyde in aqueous solution is reacted with an alkali metal sulfite or bisulfite to produce the corresponding salt, which may then be separated essentially completely by, e.g., distillation or membrane separation, etc., or its concentration in the process may be controlled by, e.g., continuous removal of a purge stream, etc.
154 METHOD AND SYSTEM FOR CONTROLLING CHEMICAL REACTION IN A MOLTEN BATH EP92914745.2 1992-07-06 EP0603197B1 1997-04-23 NAGEL, Christopher, J.
A method and a system is disclosed for controlling chemical reaction of a feed. The feed is directed into a reactor containing a molten bath to at least partially chemically react the feed to form an intermediate component. A portion of the intermediate component is combined with an off-gas which is emitted from the molten bath. At least a portion of the intermediate is then separated from the off-gas and returned to the molten bath. The returned intermediate component is then substantially converted to its atomic constituents. The atomic constituents subsequently exothermically react with other components of the molten bath for reaction to form compounds which are substantially stable at the operating conditions of the system, thereby allowing control of chemical reaction of the feed.

159 METHOD FOR INDIRECT CHEMICAL REDUCTION OF METALS IN WASTE EP93910749.0 1993-04-23 EP0639091A1 1995-02-22 NAGEL, Christopher, J.; BACH, Robert, D.; JOHNSTON, James, E.
An environmentally sound process is described for the remediation of waste materials that allows the separation, recovery and decontamination of metals. The method includes chemically reducing essentially all of a reducible toxic and potentially hazardous metal-containing component of a waste composition. The waste is directed into a molten metal bath, including a first reducing agent which, under the operating conditions of the molten metal bath, chemically reduces a metal of the metal-containing component to form a dissolved intermediate. A second reducing agent is directed into the molten metal bath. The second reducing agent, under the operations of the molten metal bath, chemically reduces the metal of the dissolved intermediate. The rate at which the second reducing agent is directed into the molten metal bath, relative to the rate at which the component of the waste is directed into the molten molten metal bath, is sufficient to cause essentially all metal-containing intermediate formed to dissolve in the molten metal bath, thereby indirectly chemically reducing the component of the waste. This indirect reduction technology can remediate a variety of materials, including ash metal-contaminated municipal waste, vitreous slag-like materials and spent metal catalysts, while allowing the recovery of remediable metals.
