...Abstract The use of alkanolamines is regarded as the most commonly used way in carbon capture and storage system (CCS) for carbon dioxide capture due to their best comprehensive effect compared with other methods. This work investigated the effect of monoethanolamine (MEA), diethanolamine (DEA...

... Degradation Abstract Corrosion in alkanolamine plants can be caused by a number of factors. Guidelines are given to maintain solvent cleanliness, acid gas loadings, solvent velocity and metallurgy required to minimize the effects of corrosion. Also, sources and ways to minimize the corrosive effects of CO...

...Abstract Although it is generally believed that Fe, Cr and Ni content in alkanolamine gas treating solutions reflects the corrosivity of the solution, we have found that this is not necessarily the case. Comparison of metals solubility by inductively coupled plasma (ICP) with carbon steel...
