Tube to Measure moisture in Recycle gas
Tube to Measure moisture in Recycle gas
(OP)
Hi all
This is regarding CCRU
We have Draeger and MSA tubes to measure HCl and H2S content in our recycle gas. But we are unable to find a suitable tube to measure the moisture content in the recylce gas. Required range would be 0 - 200 ppm. Would anyone suggest a company that has tubes of desired range?

In fact, I believe that technology was originally developed specifically for measuring moisture in hydrogen recycle gas. The only limitation that comes to mind is that you need to isolate the analyzer during regeneration due to the spike in HCl that occurs.

The on-line (not portable) quartz crystal technology comes with a built-in moisture verification function based upon a permeation tube moisture source (you see them in calibration systems) so there is no need to uninstall the analyzer to check its function.
Also, I do not believe that UOP has ever listed aluminum oxide as a recommended technology for hydrogen recycle service.
