To understand which part of the CO2 amine-based system is mostly responsible amine degradation, MEA degradation under real capture conditions compared with two laboratory experiments; a thermal experiment representative stripper (MEA 30 wt%, loaded, α=0.5, 135 °C) and an oxidative absorber α=0.4, sparged air+CO2, 55 °C). Liquid Chromatography-Mass Spectrometry (LC-MS) was used for quantification remaining Gas (GC-MS) identification main compounds. This study suggests that in pilot plant more...

2-Ethanolamine (MEA) degradation has been studied under varying conditions of relevance to postcombustion CO2 capture. Degradation experiments performed in the laboratory were chosen be representative a capture plant facility. The thermal MEA was investigated closed-batch at 135 °C different loadings. also oxidative without additives or by adding FeSO4/fly ash. These compared with three campaigns pilot plants Tiller (Norway), Esbjerg (Denmark), and Longannet (U.K.). same analytical...

Solvent degradation is one of the major challenges for amine-based carbon capture development. Oxidative appears to be influenced by combined presence oxygen and dissolved metals, particularly iron. The maximum amount iron corresponds its solubility in amine solvents. However, current literature very limited providing such data. This work aims provide a comprehensive method, developed through an investigative process, capable valuable reliable data on method based precipitation, where excess...

Liquid analysis of mono-ethanolamine (MEA) solutions was performed by Fourier Transform Infrared (FTIR) spectroscopy Attenuated Total Reflectance (ATR). Calibration spectra were obtained from a set standard MEA. A calibration model for prediction amine- and CO2 concentration in MEA PLS regression the dataset. Online solvent pilot plant demonstrated application developed using mobile setup extractive sampling to an FTIR analyser. Our results show that liquid ATR combined with multivariate...

SINTEF Materials and Chemistry has recently designed an advanced laboratory test rig for studies of solvent degradation. This degradation (SDR) emulates the process conditions observed in absorber/stripper configuration CO2 capture. Aqueous is degraded by cycling a combined absorber stripper setup with realistic temperatures loadings addition to defined synthetic flue gas mixture. A 14 week campaign 30 wt.% 2-ethanolamine (MEA) was performed rig. Comparison between group methodology specific...

Amine degradation and corrosion can be a severe operational problem in the CO2 absorption process. In this paper effect of MEA's products on is studied. Different solutions MEA 30wt% containing also 1wt% specific product were placed 316 stainless steel cylinders stored thermostat chamber at 135oC. Samples are analysed for Fe, Cr, Ni Mo by ICP-MS as an indication corrosivity. The results showed that after 5 weeks loaded with oxalic acid was most corrosive solution.

The chemical stability of aqueous amines is an essential property to study before new are introduced in pilot plants, reduce risks related the operation, cost and environment. There no standard methods for studying degradation standardized way knowing which components search for. This work will give overview current status amine research with recommendations further within this field. Degradation CO2 absorption process always occur, though some more stable than others. leads compounds...

The current paper gives an overview of the complexity solvent development for post combustion CO2 capture. Absorption rate, capacity and temperature dependence equilibria determine energy performance in optimized process. Degradability may sometimes prevent otherwise promising solvents from being utilized at energetically optimal operating conditions. Cost environmental impact are additional properties that must be fulfilled if a shall qualified deployment industrial scale. describes...

CO2 capture with alkanolamines has been in use since 1930, where 2-ethanolamine (MEA) is the most studied absorbent for post-combustion. In order to prevent degradation, it important understand degradation mechanisms, which turn requires knowledge of both stoichiometry and kinetics reactions chemical pathways associated degradation. present work thermal closed cylinders at 135 °C performed on already oxidatively degraded solutions from an open batch a setup. Thermal seems give typical compounds.

Aqueous amine solvents are used to capture CO2 from various flue gas sources. In this work, the chemical stability of a blend 3-amino-1-propanol (3A1P) and 1-(2-hydroxyethyl)pyrrolidine [1-(2HE)PRLD] was studied. The tests were conducted both in batch cycled systems using oxygen NOx concentrations, additives (iron), temperatures. thermal degradation experiments with present, more stable than primary amines [(3A1P or monoethanolamine (MEA)] but less tertiary 1-(2HE)PRLD alone.
