Heat-stable salts reduce H2S leaking from amine absorbers

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. 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.The presence of amine HSSs can cause poor sour-gas contactor and treating plant performance. The existence of HSSs is not, however, always detrimental to amine unit performance. Under certain circumstances, HSSs can actually help achieve reductions in H2S leaking from absorbers. The Khangiran gas plant, which is 40 km ...
