Sodium transport mechanisms in process streams
Sodium transport mechanisms in process streams
(OP)
Can anyone tell me if there is a mechanism for sodium to migrate from a heat stable salt in an MEA solution to a liquid particle in an acid gas stream leaving an amine regenerator tower? More specifically, I am wondering if there is a connection between a caustic (sodium hydroxide)incursion into the amine system and high sodium contamination found inside a waste heat boiler in the acid gas stream. The conditions were right for the sodium to make a mess of the boiler, but I don't know how it would have gotten from the regenerator tower into the overhead acid gas stream.

If I recall correctly that NaOH in an MEA scrubbing system under some circumstances can form some very high boiling residue. gunk. Unless the is some compelling reason I think it behoove you to clean out your system with the possibility of not recovering all the MEA. .
