In case you missed months’s webinar with Siemens on oxygen measurement in safety critical applications, we’ve put together some of the key points:
What is a safety critical application?
A safety critical application is one in which system failure could result in loss of life, significant property damage, or harm to the environment.
There are a number of critical applications that anyone in the process industry should be aware of:
- Thermal oxidizers are process units for air pollution control in many chemical plants. They work by decomposing hazardous gases at a high temperature and releasing them safely into the atmosphere. When thermal oxidizers are not working properly, they can be explosion hazards.
- A gas flare is a combustion device used in plants for burning off flammable gas released by pressure relief valves during unplanned equipment overpressure. The oxygen level in the flare gas must be set below that of where an explosion could occur.
- Inert blanketing refers to the layer of gas, typically nitrogen, that lays atop contents in a tank, container, or silo to reduce oxygen content in the vapor space, and ultimately reduce the risk of unwanted combustion. If the inert blanketing fails, there is a possibility of explosion.
