I have been trying to find information about heat stable salt. Could anyone please provide me with a list of literature or explain what heat stable salt is?

Thanks,
Dylan

If I have not mistaken, you are looking for Amine Heat Stable Salts.

An amine heat-stable salt (HSS) is the thermally-unregenerable protonated form of the amine. The HSS is itself a product of the neutralization reaction between the alkaline amine and an organic or inorganic acid (the neutralizing agent). Unless deliberately added, such acids enter the solution either as the result of degradation of the amine, or by absorption of sulfur oxides or other acid-forming components from the raw gas being treated.

Strong acid anions such as formate, acetate, thiosulfate, thiocyanate, and chloride can tie up an amine molecule to form a salt that is not capable of being regenerated by the addition of heat, and are thus referred to as Heat Stable Salts. Not only do they tie up the amine and thereby reduce the acid gas carrying capacity, but they are also considered corrosive.
