Results from aerosol measurement in amine plant treating gas turbine and Residue Fluidized Catalytic Cracker flue gases at the CO2 Technology Centre Mongstad

This work discusses the relation between flue gas particle content, mainly related to sulfuric acid aerosols and dust, and corresponding MEA emissions. The work lays grounds for future necessary pre-treatment options for various flue gases with high aerosol content in order to operate post-combustion amine plants with minimum emissions. In 2015, the CO2 Technology Center Mongstad (TCM DA), operated a test campaign using aqueous monoethanolamine ( MEA) solvent at 30 wt%. The main objective was to demonstrate and document the performance of the TCM DA Amine Plant located in Mongstad, Norway. Two weeks were dedicated to the aerosol measurement testing.

I denne oppgaven skal jeg ta for meg tre av H. C. Andersens eventyr og det danske rockebandet Shu•bi•duas adaptasjoner av dem til familievennlige sanger. Jeg ser på likheter og forskjeller, både i form og fortolkning, basert på medienes og tidens forskjeller

A random effects meta-analysis of the results from 15 projects involving price reduction and 9 projects involving increased service frequency showed that both price reduction and increased service frequency generated public transport travels. On average, the increased service frequency projects generated more travels by public transport than the price reduction projects. In the increased service frequency projects the proportion of travels generated by the increased frequency was strongly influenced by the size of the frequency increase. In the price reduction projects, we did not find a significant effect of the size of the price reduction on the proportion of travels generated by the price reduction. Finding that people’s use of public transport was related to the extent of the service offered suggests they have a need for transport that can be fulfilled with public transport. Although people appreciate lower fares in general, finding that use of public transport was not significantly related to the size of a price change suggests the effect of price change is uncertain

Effects of NOx in the flue gas degradation of MEA

AbstractPost combustion CO2 capture using amine absorbents is the most mature process and therefore the most relevant choice for realising full-scale capture within the next few years. The health and environmental impact of emissions to air is, however, a potential risk. Amines may react in the process or in the atmosphere post emission to form new substances that may be more harmful than the parent amine itself.The main objective of the current work was to investigate the flue gas degradation of monoethanolamine (MEA) in the process with special emphasis on the NOx induced chemical reactions. Degradation experiments have been carried out at absorber like conditions in the Aminox™ rig, followed by further degradation of the used solvent at higher temperature in a lab scale autoclave. Liquid samples were analysed by a range of methods to identify the formation of degradation by-products, with special focus on potential harmful compounds like nitrosamines and nitramines. On-line FT-IR and MS instruments were used for qualitative detection of volatile degradation products and to measure amine slip.MEA is a primary amine which in itself is unable to form a stable nitrosamine. However, experiments show that under the influence of NOx, MEA degrades to the secondary amine diethanolamine (DEA) which is then nitrosated. This work shows that some nitrosamine formation in the process must be expected from any amine. Based on data from real emission measurements, health and environmental risk assessment should be investigated in further studies

Results from MEA degradation and reclaiming processes at the CO2 Technology Centre Mongstad

In 2015, the CO2 Technology Center Mongstad (TCM DA), operated a test campaign using aqueous monoethanolamine (MEA) solvent at 30 wt%. The main objective was to demonstrate and document the performance of the TCM DA Amine Plant located in Mongstad, Norway. As part of the test campaign, thermal reclaiming was performed in order to eliminate accumulated degradation products and improve the solvent performance. This paper presents results and discussions concerning formation and monitoring of amine degradation products along with experiences related to the thermal reclaiming process and its operational procedure. Evaluations of the efficiency of thermal reclaiming and the solvent improvement after reclaiming are also presented.publishedVersio
