Abstract: The present invention relates to a system and a process for producing hydrogen cyanide and more particularly, to a process for controlling operational stability of the system and process by blanketing the system with inert gas. More particularly, the present invention relates to the flushing of the system with an inert gas when a crude hydrogen cyanide product exceeds a threshold of oxygen, such as greater than 0.4 vol.% oxygen.

Abstract: A flow straightener is disclosed for a hydrogen cyanide reaction process that maintains a substantially uniform velocity profile to provide a plug flow with reduced flow rotation within a mixing vessel. This results in improved performance and production of hydrogen cyanide.

Abstract: The present invention relates to a process for producing hydrogen cyanide and more particularly, to a process for economically producing hydrogen cyanide. More particularly, the present invention relates to the controlled use of a ternary gas mixture including a methane-containing gas comprising less than 1 vol.% C2+ hydrocarbons, such as, for example, less than 5,000 mpm C2+ hydrocarbons, an ammonia-containing gas, and an oxygen-containing gas for production of hydrogen cyanide at enhanced levels of productivity and yield.

Abstract: A static mixer is disclosed for a hydrogen cyanide reaction process that thoroughly mixes the reactant gases to form a ternary gas mixture that has a coefficient of variation of less than 0.1 across the diameter of the catalyst bed. The static mixer comprises tabs that are inserted through non-continuous slots in the conduit and the tabs are secured to the external wall of the conduit.
