“…Different stage cuts were studied to calculate the molar value of oxygen in permeate flow and nonpermeable nitrogen in the retentate flow. [8] Comparison of the obtained experimental data [8] with the results of the RIPI model for similar conditions (Table 1) indicates that the RIPI model performance is acceptable to a large extent.…”

In this study artificial neural network (ANN) modeling of a hollow fiber membrane module for separation of oxygen from air was conducted. Feed rates, transmembrane pressure, membrane surface area, and membrane permeability for the present constituents in the feed were network input data. Output data were rate of permeate from the membrane, the amount of N 2 in the remaining flow, and the amount of O 2 in the permeate flow. Experimental

“…La OEC surgió debido a los requerimientos de altas temperaturas de procesos que tradicionalmente empleaban grandes bancos recuperadores de calor; y se consolidó gracias a la disminución de los costos asociados a la producción de O 2 (Baukal, 2003;Chen y Axelbaum, 2005;North American Mfg Co., 1997), que la hicieron económicamente viable en procesos de alta temperatura (Sunderland et al, 2003), como la fusión de vidrio (Boushaki et al, 2007;Bennet et al, 2008), de acero (Kim et al, 2007) y de aluminio (Nieckele et al, 2004), donde se obtuvieron aumentos significativos en la productividad con bajos costos de inversión, convirtiéndolos en potenciales aplicaciones de la OEC (Fabiani et al, 1996).…”

The characteristics of oxygen-enriched combustion and perspectives regarding its application in SMEs having high-temperature processes

Small and medium-sized enterprises (SMEs) having high temperature processes, such as heat treating and melting, are socially and economically important for developing countries. Consequently, their competitiveness must thus be increased to guarantee their permanence in the market. As these companies are thermal energy intensive, their competitiveness is affected by obsolescence and the low efficiency of older combustion devices, thereby making research necessary and being open to and aware of new technologies. With this aim in mind, a review of the state of the art regarding oxygen-enhanced combustion (OEC) is presented, highlighting its productivity and environmental benefits. A brass melting process in a self-regenerative furnace is shown to account for its potential, in which 28%, 43% and 34% reductions in fuel consumption, process time and CO2 emissions were obtained, respectively, and a 30% increase in efficiency, by increasing the oxygen content in the oxidiser from 21% to 35%. However, increased O2 supply cost constitutes an obstacle to applying this technique in SMEs.

“…Two major types of primary components are present in the atmospheric air which is nitrogen and oxygen and an oxy-rich air is needed for many industrial applications [1]. Pure oxygen is required for the metal production process [2], medical processes, air humidification, combustion processes [3][4][5][6][7] and bioprocesses [8] including food packing industry [9]. The two major types of air separation processes are cryogenic distillation and pressure swing adsorption and are considered as traditional methods for air separation.…”

Air separation is a process of separating primary components from the atmospheric air. Development of membrane technologies plays a key role in air separation. Multi-layer polymeric nanocomposite membranes have been developed by a novel technique using Polyacrylonitrile (PAN) and cellulose acetate (CA) along with nano silica particles (SiO2) to obtain a higher oxygen selectivity and permeability. For the construction of the multilayer membrane, the Box-Behnken design has been used by employing three independent variables namely PAN Electro spinning time, the SiO2 percentage in the PAN polymer and CA/PEG polymer concentration. The developed membranes have been characterized for its surface morphology and physical properties. Along with the analysis of compound desirability, the results were also subject to statistical analysis in order to form regression equations. The electro spun fiber diameter increases along with the concentration of SiO2 nanoparticles and the range is from 50 nm to 400 nm. Moreover, the maximum pore size on the surface of the membrane lies between 200 to 400 nm whereas the maximum percentage of oxygen purity obtained is 48 with the permeate flux of 5.45 cm3/cm2/min.
