Catalytic oxidative ammonolysis
of methane
This process is used to produce hydrocyanic acid (HCN), which serves as the basic raw material for further production. The reaction proceeds at high temperatures in the presence of a catalyst
The plant strictly observes environmental and safety standards
Neutralization of hydrocyanic acid with caustic soda
The hydrocyanic acid obtained at the previous stage is neutralized with a solution of sodium hydroxide, which leads to the formation of sodium cyanide
Neutralization of acidic bottom liquid with ammonia
This stage is necessary to dispose of by-products, such as ammonium sulfate, which is formed during the process. Neutralization is performed by adding ammonia
The production of sodium cyanide consists of several key stages that are based on various chemical processes:
