Inhibition factors in biofilm N removal systems treating wastes generated by amine based CO2 capture
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...

Corrosion of low alloyed steel in mono ethanol amine solution
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...

Biological treatment of effluents generated by amine based CO2-capture plants
Oxidative degradation of amines using a closed batch system
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...
Biodegradation of amine waste generated from post-combustion CO2 capture in a moving bed biofilm treatment system
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...
