Amine stress corrosion cracking is most often associated with lean amine services. The pure alkanolamine does not cause cracking. Cracking in rich amine services are most often associated with _______ problems.
Amine stress corrosion cracking is most often associated with lean amine services. The pure alkanolamine does not cause cracking. Cracking in rich amine services are most often associated with _______ problems.
Amine stress corrosion cracking is most often associated with lean amine services because the pure alkanolamine does not cause cracking. In rich amine services used in H2S removal systems, the presence of wet H2S contributes to the formation of an iron sulfide film on steel surfaces, which impedes amine stress corrosion cracking. Therefore, cracking in rich amine services is most often associated with wet H2S.
Amine cracking is most often associated with lean amine services, where a solution of amine and water is used. The pure alkanolamine does not cause cracking. In rich amine services in H2S removal systems, the H2S helps form an iron sulfide (FeS) film on steel surfaces that helps impede amine SCC. Cracking in rich amine services is most often associated with wet H2S.
