Amine stress corrosion cracking is a term applied to the cracking of steels under the combined actions of ________ and __________ in aqueous alkanolamine systems used to remove/absorb H²S and/or CO² and their mixtures from various gas and liquid hydrocarbon streams.
Amine stress corrosion cracking refers to the cracking of steels under the combined actions of tensile stress and corrosion in aqueous alkanolamine systems used to remove or absorb hydrogen sulfide (H2S) and carbon dioxide (CO2) from various gas and liquid hydrocarbon streams. Tensile stress induces the mechanical loading needed to initiate cracks, while the corrosive environment causes the metal degradation that propagates the cracking.
Amine SCC (or amine cracking) is the cracking of steels under the combined action of tensile stress and an aqueous alkanolamine solution used to remove (absorb) H2S and/or CO2 and their mixtures from various gas and liquid hydrocarbon streams
