Which of the following alkanolamine systems is the most aggressive in causing amine corrosion?
Which of the following alkanolamine systems is the most aggressive in causing amine corrosion?
Monoethanolamine (MEA) is generally considered the most aggressive in causing amine corrosion among the given options. This is due to its chemical properties, which tend to make it more reactive and corrosive compared to the other alkanolamines listed. As a result, MEA is more likely to cause significant corrosion issues in systems where it is used.
Corrosion is also dependent on the type of amine used. In general, alkanolamine systems can be rated in order of aggressiveness from most to least as follows: monoethanolamine (MEA), diglycolamine (DGA), diisopropylamine (DIPA), diethanolamine (DEA), and methyl diethanolamine (MDEA).
