STUDIES OF CORROSION AND CORROSION CONTROL IN A CO2-2-AMINO-2-METHYL-1-PROPANOL (AMP) ENVIRONMENT

Corrosion and corrosion inhibition in a sterically hindered amine, 2-a mino-2-methyl-1-propanol (AMP), were investigated by static weight los s tests. The corrosion data were compared with those of monoethanolami ne (MEA), a conventional alkanolamine, which was simultaneously tested under the same conditions. The results indicated that the AMP system was generally less corrosive to carbon steel than the MEA system, but corrosion control is still necessary. Sodium metavanadate (NaVO3) and sodium sulfite (Na2SO3) were proven to be effective corrosion inhibito rs, with more than 90% protection efficiency.
