Eliminate CO2 from steam coming out of boiler
Eliminate CO2 from steam coming out of boiler
(OP)
WHAT IS GOING ON:
The steam coming out of the boiler contains CO2 which disolves in the condenser and forms carbonic acid, which causes corrosion in the condensate systems. The chemical that is being injected to control that corrosion is Tri-act.
WHAT DO I WANT TO DO:
I want to install a degeaser unit or flash drum right after the boiler unit, that will take away the CO2 from the steam and that way we wont need to inject Tri-act anymore.
If I install a flash drum, we'll have to play around with presure and temperatures, to transform steam into water and keep CO2 as gas to venet it out.
WHAT DO YOU GUYS THINK? ANY IDEA?

RE: Eliminate CO2 from steam coming out of boiler
Also, you should learn about how a deaerator works....how it removes both oxygen and CO2 to help preseve your capital investment.
That flash drum just downstream of the boiler sounds like a really bad idea. IMHO, it would require a really big vent
Please tell us.....how is your DA running ?

Having a bad morning? Nothing wrong with his format, using all caps for headers is a reasonable format.
As to trying to scavenge CO2 from steam with chemicals or a flash tank doesn't seem that great an idea either.

Yes, the deaerator removes both oxigen and CO2, but not all of the CO2 is removed since it comes out in the water as bicarbonate alkalini, which is later dissociated in the boiler when the water turns into steam and creates CO2.

Okay, so what's your idea?
RE: Eliminate CO2 from steam coming out of boiler
You need to look at optimizing your triact feed. Or look into a different neutralizing agent. Is your goal only to reduce cost?
