CO2-spikes in instrument air system
CO2-spikes in instrument air system
(OP)
Hi all,
I have a problem with CO2-spikes in an instrument air system. The spikes occurs when the air dryer unit (dessicant) switches tower. The air is also used as breathing air, and the CO2 is monitored. The analyser (ir-type) is located upstream of the dryer.
Any clues?
Thanks!

Now to your CO2 question:
Do you find any Co in the instrument air?
How is the instrument air generated?
Is there a carbon filter in line?
How are the dryers regenerated?
Remember that Atmospheric air has a little CO2, too much for some, that could be adsorbed and release during the change over.

The dryer is an old BURNETT & LEWIS, heat regenerated, with Activated alumina and Mobil Sorbead Grade R.
