  • Method and device for destroying reaction gases by incineration
    Patent number: 6228250
    Abstract: In a method for destroying one or more gases by combustion, hydrogen is used as the principal fuel in the presence of oxygen. Hydrogen is generated in situ by an electrolysis reaction.
    Type: Grant

  • Device for destroying reaction gases by incineration
    Patent number: 5948372
    Abstract: A device for destroying by electro-oxidation a photographic solution having at least one photographic developer. The device comprises a) an electro-oxidation unit adapted to degrade the photographic developer into volatile organic compounds and to produce hydrogen and oxygen, b) an expansion reservoir designed to contain the gaseous mixture generated by said electro-oxidation unit; and c) a combustion unit supplied with the gaseous mixture from the expansion reservoir.

  • Process for the electro-oxidation of photographic solutions
    Patent number: 5725751
    Abstract: The invention concerns a process and a device for the treatment by electrolysis of used photographic solutions containing developers in an electrolytic cell comprising at least one platinum anode. The invention enables the corrosion of the platinum anode to be minimized by using an efficient quantity of antifoaming agent and keeping the pH constant at a value equal to or above 10.5 at the beginning of electrolysis. The invention enables the quantity of platinum coming from the anode in solution to be reduced.
