Detection methods for CO in circulating hydrogen and fresh hydrogen in hydrogenation units
Thread Content
Dear sea friends: What methods are used to detect carbon monoxide in circulating hydrogen and fresh hydrogen in hydrogen production units? At present, our company uses chromatography for this purpose, but technology providers such as AXENS do not approve of this method; they recommend using Degussa test tubes or UOP603 for testing. What are everyone’s thoughts on this? What testing methods are you using?
Bro, use the expensive one! You get what you pay for; the more expensive options should offer higher accuracy. We use chromatography……
Chromatography is sufficient; it is not a key reference indicator.
I would like to know the reasons behind AXENS?
