We produced porous ceramics for gas separation using membrane formation of Nd 2 Fe 14 B powders on alumina (Al 2 O 3 ) support. The average pore size and porosity of the alumina support were, respectively about 67 mm and 3440%. Selectivity of this support was about 1.07, which well agreed with Knudsen diffusion. The coated Nd 2 Fe 14 B membrane thickness was about 166¯m. The sample selectivity after membrane formation was 1.07. Gas selectivity properties were not developed. When magnetized on the same sample, gas selectivity appeared at low differential pressure at gas permeation. Samples with a lower gas flow rate of the alumina support exhibited higher selectivity. The maximum was 1.22.

“…In this context coal has to be considered as energy source for power generation because of its availability and relatively wide geographic distribution. These developments include coal based electric power technologies, where the integrated gasification combined cycle (IGCC) is an alternative to pulverized coal (PC) combustion systems (Descamps, Bouallou, & Kanniche, 2008;Karg, Haupt, & Zimmermann, 2000;Park et al, 1999;Zheng & Furinsky, 2005), as they obtain higher efficiencies and better environmental performance (Jay, Lynn, Jeff, & Massood, 2002;Minchener, 2005;Ordorica-Garcia, Douglas, Croiset, & Zheng, 2006;Park et al, 1999). In comparison with modern coal combustion technologies (pulverized coal combustion (PCC), fluidized bed combustion (FBC), supercritical and ultra-supercritical technologies), IGCC systems are characterized by lower SO x and NO x emissions, comparable vapor organic carbon (VOC) emissions, 20% less CO 2 emissions and use of 20-40% less water.…”

“…Before CO 2 can be sequestered it must be captured as relatively pure CO 2 from power plants and other sources. In IGCC, as coal is not combusted, the relatively small volumes of synthesis gas (syngas) are easier to clean up than the much larger volumes of flue gases at coal combustion plants (Descamps et al, 2008).…”

a b s t r a c tThe integrated gasification combined cycle (IGCC) is an electrical power generation system which offers efficient generation from coal with lower effect on the environment than conventional coal power plants. However, further improvement of its efficiency and thereby lowering emissions are important tasks to achieve a more sustainable energy production. In this paper, a process simulation tool is proposed for simulation of IGCC. This tool is used to improve IGCC's efficiency and the environmental performance through an analysis of the operating conditions, together with process integration studies. Pinch analysis principles and process integration insights are then employed to make topological changes to the flowsheet to improve the energy efficiency and minimize the operation costs. Process data of the Texaco gasifier and the associated plants (coal preparation, air separation unit, gas cleaning, sulfur recovery, gas turbine, steam turbine and the heat recovery steam generator) are considered as a base case, and simulated using Aspen Plus ® . The results of parameter analysis and heat integration studies indicate that thermal efficiency of 45% can be reached, while a significant decrease in CO 2 and SO x emissions is observed. The CO 2 and SO x emission levels reached are 698 kg/MWh and 0.15 kg/MWh, respectively. Application of pinch analysis determines energy targets, and also identifies potential modifications for further improvement to overall energy efficiency. Benefits of energy integration and steam production possibilities can further be quantified. Overall benefits can be translated to minimum operation costs and atmospheric emissions.
