Ammonia presence in DEA Stripper top stream
Ammonia presence in DEA Stripper top stream
(OP)
S!
We are facing problems due to the presence of ammonia in the top stream of the DEA Stripper on the DEA system of a FCC unit, the one rich in H2S.
I wonder the origin of the ammonia? Could thermal degradion leads to ammonia formation?
Best regards

Seen the same also in a MDEA regenerator
Need a water addition to reduce the NH3 levels
If not the combined high levels of NH3 and H2S might create corrosion and deposits in th gas line
This NH3 came from the gas stream to the absorbers
Had no consumption of MDEA or any high levels of HSS

Every amine plant I've worked in always had that ammonia "smell" in the still reflux condensor water. These units were mainly on natural gas streams so there was absolutely no way of having ammonia in the feed stream.
