Definitions

  • Lime residues containing cyan are treated with silica sand or silica sand residues in an autoclave at at least 110 ° C and 2 bar pressure with water vapor, whereby CaCN 2 is broken down into CaCO 3 and ammonia.
  • the process of stone production corresponds to the known manufacturing process of sand-lime bricks.
  • the stones are then treated with steam in an autoclave at 180 ° C and 10 bar pressure for 8 hours.
  • Calcium hydrosilicates are formed and the cyan compounds are decomposed in 1.25 kg CaCO 3 and 425 g ammonia.
  • the ammonia-containing water vapor is removed from the autoclave and 425 g of ammonia are converted to 1.650 kg of ammonium sulfate with 1.225 kg of sulfuric acid.

Abstract

Selon l'invention, des résidus de calcaire contenant du cyanogène sont traités à la vapeur d'eau, avec du sable siliceux ou des résidus de sable siliceux, dans un autoclave à une température d'au moins 110 DEG C et une pression de 2 bars. Cette opération a pour effet de décomposer le CaCN2 en CaCO3 et en ammoniac.
