Helene Lepaumier, Auteur ; Dominique Picq, Auteur ; Pierre-Louis Carrette, Auteur |Degradation of 12 different amines with CO2 was evaluated in 100 mL stainless steel batch reactors for 15 days at 140 °C using a 4 mol·kg−1 amine solution and a CO2 pressure of 2 MPa. At the end of the run, most of degradation products were iden[...]

Helene Lepaumier, Auteur ; Dominique Picq, Auteur ; Pierre-Louis Carrette, Auteur |This study examines oxidative degradation of 12 ethanolamines and ethylenediamines. They were chosen to establish structure−property relationships: the role of replacement of the alcohol function by one second amine function, amine nature, steri[...]

Helene Lepaumier, Auteur ; Sandrine Martin, Auteur |This study examines degradation of five tertiary polyamines (di- and triamines) in the presence of CO2 or O2. They were chosen to identify the impact of alkyl chain length between amine functions. Degradation of aqueous amine solutions was evalu[...]

Sandrine Martin, Auteur ; Helene Lepaumier, Auteur ; Dominique Picq, Auteur |Degradation of 22 compounds was evaluated in stainless steel batch reactors at 140 °C for 14 days under a pressure of 0.5 MPa (mixture of 75% CO2, 20% N2, and 5% O2). For each run, two corrosion coupons, one carbon steel (XC38) and one stainless[...]

Eirik F. Da Silva, Auteur ; Helene Lepaumier, Auteur ; Andreas Grimstvedt, Auteur |2-Ethanolamine (MEA) degradation has been studied under varying conditions of relevance to postcombustion CO2 capture. Degradation experiments performed in the laboratory were chosen to be representative of the conditions in a CO2 capture plant [...]
