| dc.description.abstract | CO₂ capture has proven to be the best way to reducing a great amount of CO₂ emissions from industries, and has obtained a great deal of research work. 1-DMA-2P is one of the commercial amine absorbents with a bright future in absorption. These commercial amine absorbents have much higher absorption and cyclic capacities than the ordinary MEA. The purpose of this research is to study Physical solubility for CO₂ in amine (1-DMA-2P) by applying the N₂O strategy. The experiments were carried out using a Novel technique method, firstly the method was tested by measuring solubility for CO₂ in water, N₂O in water, then lastly N₂O in 1-DMA-2P. Subsequently, physical solubility for CO₂ in 1-DMA-2P was calculated by deriving the data achieved from N₂O in 1-DMA-2P following the N₂O Analogy theorem. Experiments amine were of 15%, 30%, 50%, 65%, 80% and pure amine (100%) at various temperatures between 298.15 K and 333.15 K. In order to compensate for the first 10 seconds of absorption, videos of the absorption during the measurements was taken, and an application of regression analysis was performed using a polynomial model from OriginPro 7.5 program. The objective of this was to make sure that absorption results were solid and accurate. Concerning the data of the solubility for CO₂ and N₂O in water, not enough experiments were conducted therefore literature values were used for the calculation of the solubility for CO₂ in 1-DMA-2P. The data from N₂O and CO₂ in amine was inserted in a linear model, and correspondingly the results for Physical solubility for CO₂ in 1-DMA-2P proved to be much better than the Physical solubility for CO₂ in MEA, and in good agreement according to the literature review research. Nevertheless, more research is still essential for commercial amine absorbents. | nb_NO |
