Patent

CA 2155672

A process and apparatus for the production of litharge, in which molten lead is reacted with oxygen at a temperature above the melting point of litharge, whereby litharge is formed as a liquid product. In a preferred embodiment, oxygen is injected into a bath containing molten lead in such a manner that the velocity of the injected gas as it expands into the bath is at least Mach 1. In order to minimise corrosion of the reaction vessel, its walls are composed of heat conductive material, externally cooled whereby heat is withdrawn from the internal surface thereof, to keep the internal surface temperature preferably below the melting point of litharge, and more preferably below the melting point of lead.

Procédé et appareil destinés à la production de litharge. Selon ce procédé, du plomb fondu est mis en réaction avec de l'oxygène à une température supérieure au point de fusion de la litharge, permettant ainsi d'obtenir de la litharge sous forme d'un produit liquide. Selon un mode préféré de réalisation, de l'oxygène est injecté dans un bain contenant du plomb fondu de façon que la vitesse du gaz injecté, tandis qu'il se dilate dans le bain, est d'au moins Mach 1. Afin de minimiser la corrosion du réacteur, les parois de ce dernier sont composées d'un matériau thermoconducteur refroidi de l'extérieur, la chaleur étant extraite de la surface interne des parois afin de maintenir la température de ladite surface de préférence à un niveau inférieur au point de fusion de la litharge et, idéalement, à un niveau inférieur au point de fusion du plomb.
