FTIR combined with multivariate analysis for monitoring of solvent composition in CO2 capture plant.
For post combustion CO2 capture, solvents which are blends of amines and/or other additives are often used. Monitoring of the solvent composition is needed for optimal performance. Today, monitoring is often done manually. Using multivariate calibration models (PLS-R) based on FTIR spectra could be ...

Evaluation of MEA data from different lab set-ups
The webinar will present results from this year investigating 2-ethanolamine (MEA) data from different lab set-ups. 2-ethanolamine (MEA) are the most studied amine when it comes to identification of degradation compounds and pathways for their formation. A lot of degradation data is therefore availa...
Multi-component Analysis of amine solvent by FTIR and PLS
The webinar will present results from a paper published earlier this year investigating multi-component analysis of amine solvent by FTIR and PLS Partial least square regression (PLS-R) methodology have been applied on dataset containing FTIR spectra and densities for a large set of MEA solvent samp...
Recovery of valuable metals from industrial waste streams
Multi-component analysis of monethanolamine solvent samples by FTIR
Partial least square regression (PLS-R) methodology have been applied on dataset containing FTIR spectra and densities for a large set of MEA solvent samples. The prediction capabilities for the major compounds were tested on different set of realistic degraded solvent samples ranging from bench sca...
Solvent technology – environmental issues
Lessons Learned Solvent Stability
The webinar will concern chemical stability/degradation of solvents candidates for CO2 capture. Solrun Johanne Vevelstad will present lessons learned from studies which included impact of the molecular structure and formation pathways. Hypothesis based on literature data and in-house competence for ...
