“…Similarly, to the overall mass transfer coefficient, the CO 2 flux increased with an increase in the absorbent flow rate in the lumen fiber of the contactor for both feed gases, due to increasing turbulence in the solvent boundary layer. Similar trendswere also demonstrated by Yan et al (2007) and Wang et al (2005). In this study, the CO 2 flux increased from 7.3×10 -7 to 4.52.1×10…”

The aim of this study is to evaluate the effects of absorbent flow rate on CO 2 absorption through a super hydrophobic hollow fiber contactor. The absorbent used in this study was a physical absorbent, namely a polyethyleneglycol-300 (PEG-300) solution. Meanwhile, the feed gases used in the experiments were pure CO 2 and a mixture of 30% CO 2 and 70% CH 4 . Gas absorption using a physical absorbent provides various benefits; for example, it can produce sufficiently high selectivity towards CO 2 and it is less corrosive than chemical solvents. Three super hydrophobic hollow fiber contactors, each 6 cm in diameter and 25 cm in lengthconsist of 1000, 3000 and 5000 fibers, respectively, were used in this study. The type ofsuper hydrophobic fiber membrane used was polypropylene-based, with an outer and inner diameter of about 525 and 235 µm, respectively. During the experiments, the absorbent was flowed through the lumen fibers, whilst the feed gas flowed through the shell side of the membrane contactors. The experimental results showed that the mass transfer coefficient, the flux, and the absorption efficiency increased, but the CO 2 loading decreased, with increasing absorbent flow rate in the membrane contactor. Meanwhile, it was found that an increase in the number of fibers in the membrane contactor, in general, will increase the absorption efficiency and the CO 2 loading, but will decrease the overall mass transfer coefficient and the flux.

“…MA, that is using a membrane in conjunction with chemical absorption, is considered as a suitable alternative to chemical absorption by many researchers, due to its unique advantages including large interfacial area, good device-modularity, good operational flexibility, and high mass transfer coefficient (Rangwala 1996;Falk-Pedersen and Dannström 1997;Feron and Jansen 2002;deMontigny et al 2005;Yeon et al 2005;Yan et al 2007Yan et al , 2008Yan et al , 2011. In addition, membrane CO 2 absorption technology can also solve the operating problems, successfully including entrainment, flooding, and foaming.…”

“…Because of the constant liquid-gas contact area, the total membrane contact area can be easily scaled-up linearly based on some successful projects or even the experimental results. According to literature (Yeon et al 2005;Yan et al 2007Yan et al , 2008Yan et al , 2011, the total membrane contact area could be calculated.…”

This study aims at determining the optimal CO 2 separation technology for Chinese refineries, based on current available technologies, by the method of comprehensive evaluation. Firstly, according to the characteristics of flue gas from Chinese refineries, three feasible CO 2 separation technologies are selected. These are pressure swing adsorption (PSA), chemical absorption (CA), and membrane absorption (MA). Secondly, an economic assessment of these three techniques is carried out in accordance with cash flow analysis. The results show that these three techniques all have economic feasibility and the PSA technique is the best. Finally, to further optimize the three techniques, a two-level fuzzy comprehensive evaluation model is established, including economic, technological, and environmental factors. Considering all the factors, PSA is optimal for Chinese refineries, followed by CA and MA. Therefore, to reduce Chinese refineries carbon emission, it is suggested that CO 2 should be captured from off-gases using PSA.

“…Use of membrane devices in a process of purification of biological methane from СО 2 is extensively studied nowadays (Atchariyawut, et al, 2007), (Al-Marzouqi, et al, 2008), (Yan, et al, 2007), , (Li, & Chen, 2009), (Mansourizadeh, & Ismail, 2009). Generally those are devices on a basis of hollow fiber membranes, comprising porous polymer fibers.…”

The presented paper describes energy saving technology of biogas purification by microbubling method Description of a new design of microbubling equipment for gas-liquid solution and mathematical simulation of a process during chemisorption of carbon dioxide are presented. Experimental studies of mass transfer characteristics of microbubling equipment, based on model systems, were conducted with an aim to define a possibility of application of microbubling process for removal of carbon dioxide from biogas in order to obtain highly concetrated metane. As a result of the study optimal process parameters are defined, key factors affecting mass transfer characteristics of membrane microbubling method are also established. Efficiency of membrane microbubling equipment from the point of view of interphase mass transfer is assessed.
