Pipeline purging
Thread Content
During the purging process of the pressure swing adsorption unit in my installation, pressure retention from a gas storage source was used for purging. Due to the high flow rate at the outlet of the pipelines during purging, the outlet appeared blue-violet in color. Excuse me, what phenomenon is this? Is it charged with static electricity?
Is it the discoloration of the pipeline outlet material~~ or is the airflow colored? ~~
Normal – compressed oxygen is blue, isn’t it?
Oxygen is colorless~~liquid oxygen has its natural color, while the solid form appears as blue crystals~~Additionally, oxygen is not used in purging processes; its flammability determines its level of danger~~~
We didn’t observe this phenomenon during purging; you’re using a magic medium
It’s not that you’re using oxygen for purging; there is oxygen in the air. You’re using pressure retention for purging, and when the density of the air increases, this happens. You know the color of liquid oxygen now too. Still can’t understand this?
Oxygen is colorless as long as it is in gaseous state~~Physical knowledge~~
There is a gradual process: the density increases over time, and the color also changes gradually; it doesn’t go from a gaseous state to a liquid state all at once, nor does it change from colorless to blue instantly. If you don’t understand me at all, there’s nothing I can do. Or ask someone else!
The pipeline purging medium is industrial air, and pressure retention purging using a gas storage tank is employed to achieve effective purging.
