Hello everybody,
In our diesel hydroteater stabilizer column currently using as stripping agent H2 gases from Platformmer:
- purity 85mol.%
- flow rate 150 - 200kg/h
Since we start our PSA(pressure swing absorber), we intended to replace H2 gases with PSA Tail Gas so we proceed to a test-run(...
Yes, it`s an existing one.
from visual inspection trays are OK, no flooding(stable pressure)
for stripped water, the sample point is in front of the pump, no leaking because according with Lab. data(as an example for yesterday: inlet outlet(bottom)
NH3 content,mg/l 1815...
Thanx siretb,
condenser temperature 95oC.
about pH, attached is a set of lab.data, please have a look on it.

We are operating a SWS, 22 trays, non-refuxed, steam reboiled as followed:
Top presure = 1.1barg
Top temperature = 122oC
Bttm temperature = 127oC
Feed flow rate = 48m3/h, on top tray
Feed temperature = 115oC
Feed composition: Ammonia = 1545mg/l; H2S = 11.9mg/l; total cyanide = 4.25mg/l;pH = 9.2...
