What are the contents of the oxygen outlet?
The oxygen outlet primarily contains oxygen (O₂) and a little amount of water steam at less than 55°C (depending on the room temperature). As it is not meant for further usage, there might be small amounts of H₂ and traces

The oxygen outlet primarily contains oxygen (O₂) and a little amount of water steam at less than 55°C (depending on the room temperature). As it is not meant for further usage, there might be small amounts of H₂ and traces of KOH/K₂CO₃. Normal H₂ concentration at the oxygen vent is under 3%, in the production range 60%÷100%, up to 30barg (at the beginning of life). In transient conditions (such as ramp-up and ramp-down) and in the event of stack failure, a flammable mixture shall be expected and managed accordingly (venting to a safe area without ignition sources along/around the vent system). A water trap is recommended to separate the water from the oxygen at the vent outlet. Ensure that the oxygen vent and hydrogen purge line outlets are led to safe areas and not close to each other.
