Corrosion of low alloyed steel in mono ethanol amine solution

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1424279

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...

Integration aspects of reactive absorption for post-combustion CO2 capture from NGCC (natural gas combined cycle) power plants

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1172026

Reactive absorption of CO2 with MEA (monoethanolamine) has been established as the preferred reference technology in benchmark studies of novel post combustion CO2 capture technologies. However, recent advances in solvents tailored for CO2 capture warrant an updated reference for consistent performa...

Process modifications for solvent-based post-combustion CO2 capture

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1213924

One of the major limitations to the implementation of amine based post-combustion CO2 capture (PCC) technology is the high efficiency loss induced by the process. Minimizing this loss can be achieved by either formulating new solvents and/or optimizing the process flow-sheet and/or its integration w...

Membrane contactors for CO2 absorption - Application, modeling and mass transfer effects

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1138223

Modeling of membrane contactors as absorber units requires a rigorous absorption model where the liquid phase is discretized in the radial direction. The current paper describes such a model for absorption of CO2 into aqueous alkanolamines. The model is validated with a large volume of experimental ...

Use of metal-organics based solvents for CO2 capture

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1190277

There are a number of metal-organic compounds that can loosely be considered CA mimics and which are known to absorb CO2 directly from the atmosphere. The metal-organic complex, {Zn[N[CH2(2-py)]3](μ-OH)}2(NO3)2 (I), is one such complex. In the present study, the sorption of CO2 by water solutions of...

CO2 absorption with membrane contactors vs. packed absorbers-Challenges and opportunities in post combustion capture and natural gas sweetening

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1070512

The present work presents a case study where membrane contactors are compared with absorption towers for post combustion CO2 capture and for natural gas sweetening. Simulations are performed using a absorber model which has been validated with experiments in a membrane contactor setup. The design of...
