De-NOx reactor fouling
De-NOx reactor fouling
(OP)
There is a De-NOx reactor in our CDU(Crude Distillation Unit) heater system.
The effluent gas from the heater enter this reactor.
It is a selective catalytic reactor with ammonia injection.
From time to time. we encounter high pressure drop in the reactor. Especially when this plant start up after a long
time shut down.
We use #6fuel oil with sulfur content of 1% in this heater.
