material, , from pure isotherms,24,74 a good option is to multiply this pure isotherm for the adsorbed molar fraction, as implemented by Prats et al.54 2.3.1. Impurities Whereas CO2 and N2 account for about 90% of the flue gas composition and can reach up to 95-97% before entering its final separation stage,75 understanding the effect of traces gases is critical to properly evaluate any material for use in a realistic CO2 capture process.7,76 If these unwanted species are not completely removed in previous separation stages, they can compete for the adsorption sites on the adsorbent material and hence, the adsorption properties and final performance can be drastically affected. According to this, studies on the influence of coexisting trace compounds in the mixtures or possible “poisoning” of the adsorbent materials allow assessing the final performance of the material at process conditions, where these impurities may be present. In order to quantify the effect of impurities on the performance of the selected materials for CO2 capture, simulations were carried out maintaining a CO2 composition of 15% in the flue gas and varying for different impurities compositions (nitrogen was used as the surplus). Concentrations as high as 1% (i.e., 10,000 ppm) of H2O, SO2 and NO2 in the mixture were evaluated in order to magnify the effect of these traces in the flue gas may be present due to inefficiencies in the previous removal systems. 2.4. Energy requirements for regeneration of the bed adsorber One of the requirements for the industrial application of these materials is to have an effective and less energy-consumed regeneration of the CO2 captured adsorbents. The most common regeneration techniques for swing adsorption processes include: (1) adsorb 14PDF Image | swing adsorption processes for CO2 capture in selected MOFs and zeolites
