摘要:
A method and a plant for processing combustion residues, particularly residues from the purification of household or industrial waste incineration fumes. Fly ash is structured by liquefying it with a gas/water mixture with a surfactant to give an ash-containing foam which is then continuously fed into a heated chamber (12) and destructured by flash vitrification therein.
摘要:
A method and a plant for processing contaminated waste, wherein unsorted waste is fed directly into a reactor (101) supplied with a solvent for dissolving polymers in said waste, whereafter the dissolution reaction is performed in said reactor at a temperature no lower than the melting point of said polymers, and the resulting uniform sterilized liquid is recovered to enable a final incineration process. Said method is particularly suitable for processing hospital waste, whether it is liquid, aqueous or organic waste or composite waste.
摘要:
The invention relates to a method for crystallizing an aqueous solution. According to the invention, said method consists in the following steps: at least one surfactant is initially added to the aqueous solution if the aqueous solution does not at least already contain one natural surfactant; the volume of the medium is subsequently swollen to form foam, whereupon crystallization occurs in a structured medium in the form of foam and said structured medium is used as a provisional material support for crystals undergoing a process of formation, after which the crystals or agglomerates of crystals are recovered by destructuring said foam.

摘要:
The invention concerns a method and a device for heat treatment of finely divided solids, which consist in organising a gradual and continuous unidirectional displacement of solid particles along a vibro fluidised bed, and in subjecting said particles to a heat treatment at medium or high temperature while they are being displaced. The invention is characterised in that the heat treatment is performed by heating from the outside the conveying tube (10), and the solid particles are displaced under controlled atmosphere in said heated tube (10) up to a hot centrifuge (20) so as to avoid condensation of the condensable gas fractions, with vapour and gas evacuation, and recuperating the solid residues.
摘要:
A method for incinerating a combustible material (1), wherein, prior to the combustion process (13), the material is divided (2) into particles, the particulate material is added (3) to an aqueous medium such that the proportion of solid material to liquid is no greater than 35 % wt. and the suspension is foamed and pressurized by inserting an oxidant gas (10) and surfactant additives (9) into a mixer (8) for the suspension.
摘要:
Procédé de traitement de déchets organiques principalement liquides consiste à réaliser un mélange aqueux des substances à incinérer à laquelle on ajoute un hydrocarbure du type fioul (14) et des agents tensio-actifs (3), à agiter ce mélange en y incorporant un gaz (7) non combustible afin de créer une mousse et à introduire cette mousse dans un foyer de combustion (9).

摘要:
The invention concerns a method for making activated carbon with permanent magnetic properties, comprising the following steps: a) impregnating the raw material with an aqueous transition metal salt solution; b) filtering and drying the impregnated dried raw material; c) performing a pyrolysis cycle of the dried filtrate, gradually increasing the temperature up to a set temperature not less than 600 °C, and maintaining said temperature during sufficient retention time to obtain the desired degree of activation. The invention also concerns an activated carbon with ferromagnetic properties obtained by said method, said activated carbon being characterised in that it comprises transition metal oxide crystals closely embedded in its carbon structure whereof the micropores are not obstructed.
