Abstract

Post combustion CO 2 capture (PCC) through reactive absorption is a promising technology to tackle climate change. The application of new solvents enables a reduction in energy demand. This research work discusses the suitability of aqueous sodium glycinate (NaGly) as a CO 2 absorption solvent.
Laboratory studies show slow absorption kinetics and moderate CO 2 absorption capacities of aqueous NaGly. Results from pilot plant tests at the coal-fired power plant in Dürnrohr, Austria, with 15, 25 and 40 wt% NaGly are presented and discussed. Realistic industry conditions were achieved through the use of flue gas from the power plant and the well-conceived dimensions of the test facility. Low
energy consumption of aqueous NaGly was mainly predicted by simulations in literature (∼3 GJ/t CO 2 ).
The measured energy consumption in the present work is much higher (> 5 GJ/t CO2 ). This represents an increase of 40% with respect to 30 wt% monoethanolamine (MEA), not combined with enhanced system
extensions. The low predicted optimal solvent flow rate could not be confirmed in the present work. The optimal liquid to gas ratio is in the range of 7–8 l/m 3
