In this work the corrosion rate of UNS(1) K12000 (DIN(2) 17100 ST 52) low-alloy structural steel in monoethanolamine (MEA) solution was studied. The corrosion testing was mainly performed on a rotating disc electrode, and electrochemical impedance was used to estimate the corrosion rate. The paramet...

We have previously shown that biological nitrogen removal by pre-denitrification as illustrated may be a feasible approach for treating wastes generated by amine based CO2 capture. In order to identify limiting factors for successful up-scaling, we first compared the nitrifying activity of moving be...

SINTEF Materials and Chemistry has recently designed an advanced laboratory test rig for studies of solvent degradation. This solvent degradation test rig (SDR) emulates the process conditions observed in an absorber/stripper configuration designed for CO2 capture. Aqueous solvent is degraded by cyc...

Oxidative degradation experiments on five amines and two amino acids were performed in a new closed setup at atmospheric pressure. For most of the amines/amino acids significant degradation was not present under these conditions, except for MEA and MMEA. The degradation compounds found seem to follo...

Large-scale amine-based CO2 capture will generate waste containing large amounts of ammonia, in addition to contaminants such as the actual amine as well as degradation products thereof. Monoethanolamine (MEA) has been a dominant amine applied so far in this context. This study reveals how biologica...

Nitrogen and organic matter removal from reclaimer waste of a monoethanolamine (MEA) based CO2-capture plant was demonstrated in a pre-denitrification biofilm system. The reclaimer waste was generated from a 30 % (w/w) MEA solvent used for capturing CO2 from flue gas from a coal-fired power plant. M...
