Prevention is the key to safety

Prevention is key to safety

Commodity processing, handling and storage generates dusts, gases and vapors. Auto-ignition and smoldering resulting from these processes can quickly turn into a fire or explosion and put your personnel, production and assets at serious risk.

Prevention requires reducing the probability of risk by reducing or eliminating some of the risk factors. Using intelligent emergency inerting systems for explosion protection or fire protection, it is possible to reduce the risk of the occurrence of critical operational conditions.

Yara inerting systems use inert gases to prevent fires and explosions. Inert gases are very stable. Their introduction reduces the oxygen level to below the critical concentration level, making it impossible for a fire or explosion to occur. By preventing the formation of explosive atmospheres, Yara inerting systems keep your industrial installations safe.

Controlling the Explosion Triangle

Controlling the explosion triangle

For a fire to occur three elements of the fire triangle must be present: fuel (gas, dust ...), the oxidant (oxygen in air) and the activator (heat) for an explosion to occur a fourth element must be present: containment (mill, filter, silo). The fuel and the activator cannot be removed from the equation, but the oxidant can. That is principle upon which Yara’s inert gas injection systems operate.

Inert gases have the property of being unresponsive and by replacing the oxidant they reduce oxygen levels to below critical concentration thresholds. The use of inert gases can prevent the ignition of dusts, gases or vapors and prevent oxidation and moisture absorption of certain sensitive products.

Materials used: inert gases

Emergency Inerting SystemsInert gases listed below are used in Yara inerting processes:

  • Carbon Dioxide
  • Steam
  • Flue Gas
  • Nitrogen
  • Noble gases

Combustion gases and / or steam can be used in most applications, but are not available in the start-up and shutdown phases of industrial facilities. In practice, carbon dioxide (CO2) and nitrogen are most often used. CO2 is the most often recommended because it is easier to store.

Yara fire prevention and explosion prevention inerting technology is based on the precisely controlled injection of inert gases such as carbon dioxide (CO2) and N2.

For example, during the normal operation of a coal pulverizer, inerting is naturally provided by the combustion gases from the furnace. In the event of a technical problem or during start-up or shutdown, the coal mill will be free of inert gases. It is in these cases that Yara offers an additional source of reliable inert gas to secure your industrial installation and its employees.
