Thanks- it’s nice to know I’m not the only one stubbing my toe on the yellow brick road, or banging my head against a yellow brick wall. We use MEA in 10-18% strength. I’m not talking HSS but rather elemental sodium as measured in an amine test. I don’t know what form it is taking in the amine. My concern/wonderment is the potential for sodium to be carried out of the amine with the acid gas. Does anyone know of a transport mechanism for sodium or sodium hydroxide to leave the liquid stream and go out with the vapor stream?
