A non-equilibrium approach to study the corrosion behavior of carbon steel in diethanolamine–H2O–CO2 systems
Source abstract
Abstract
Abstract The present study aims at investigating the aggressiveness of the major CO2-containing species of diethanolamine (DEA)–H2O–CO2 system, namely DEA carbamate and bicarbonate ions towards carbon steel via a non-equilibrium approach which allowed different ratios of carbamate to bicarbonate concentrations to be obtained. EIS and polarization tests were performed on AISI 1018 carbon steel specimens which had been exposed to the designed test systems. The results indicated that bicarbonate ion led to depassivation of steel while on the other hand no significant aggressive nature was detected for DEA carbamate ion.
