Abstract:
Present invention relates to a process and an installation ( 100 ) for the preparation of hydrogen cyanide by the Andrussow process, and more precisely for improving the conditions of mixing the reactant gases before feeding the Andrussow type reactor ( 60 ), in order to improve safety, to avoid any risk of explosion and to produce HCN in safe and efficient manner. The installation is configured in such a manner that oxygen is pre-mixed with air with a ratio comprised between 20.95% and 32.5% by volume, preferably between 25% and 30.5% by volume; methane containing gas and ammonia are simultaneously added in the pre-mixture of oxygen-enriched air in such a manner that the volumic ratio of methane to ammonia is comprised between 1.35 and 1.02 depending on the content of oxygen into air; said obtained reactant gases mixture having a temperature comprised between 80° C. and 120° C., preferably between 95° C. and 115° C. for feeding the Andrussow type reactor ( 60 ).

Claim (Index 4):
Installation according to  claim 3 , wherein said installation further comprises a second static mixer ( 16 ) designed to homogenize the composition of oxygen-enriched air before the addition of methane containing gas and ammonia.
