"Apparatus for heat exchange for use in an environment of reduction, fuel and / or nitrification for heat exchange for use in a reactor of hydrogen cyanide.To prepare hydrogen cyanide by reaction of hydrocarbon, and optionally amu00c8nia gas containing oxygen, ferrule for use in a tube for heat exchange, and.Process for preparing hydrogen cyanide.Means are exposed to improve the service life of heat exchanger of the type of sheet to tube indirect used in chemical reactors, particularly those exposed to environments of reduction.Nitrification and / or carburetor. These means include the use of certain ferrules inside the tubes of heat exchange and / or welding types used in the construction of these heat exchangers.
