Hydrogen production PSA separator tower
Thread Content
I would like to ask the experts: what should be taken into consideration when producing hydrogen followed by PSA tower operation? Yesterday, the furnace was at positive pressure
What is the cause of positive pressure? It is the positive pressure in the furnace caused by Cheta’s analysis of gas fluctuations!
Yes, the reverse flow pressure is too high; the gas pressure after cutting is high
Is the chetta related to the positive pressure in the furnace? What process?
First, it depends on how many towers there are; sometimes, when working with different towers, the adsorption time needs to be adjusted. Second, when cutting the tower, make sure to do it when its pressure is low to ensure safety. Thirdly, when cutting off the feed, it is essential to control the amount of purge gas entering the conversion furnace; at critical moments, any excess purge gas should be vented through a flare, otherwise the conversion furnace will be at risk.
Yesterday was indeed quite dangerous; the furnace was under positive pressure, and the furnace chamber was completely red!
