Phosphine removal from air
Phosphine removal from air
(OP)
I have to remove Phosphine (PH3) from air through a scrubber. I read it is possible to use NaOH solution with an oxidant (NaClO, or H2O2 or KMnO4). Has somebody an experience with this type of scrubbing or do you know another way for removing PH3. (I cannot use thermal oxidation)
Thank you for help

There are granular activated carbons that have been used in this application. However, before recommending the use of carbon the following information is required.
Your flowrate, concentration, temperature and pressure?

The flow rate is 1620 Nm3/h, pressure is 4 kPa (g) temperature is 20 °C PH3 concentration is 500 ppm vol and water content is 2% vol
