a novel co2 resistant ceramic dual phase hollow fiber membrane for oxygen separation
Journal of Membrane Science, 2017Co-Authors: Xiuxia Meng, Pengyun Liu, Naitao Yang, Zhonghua Zhu, Ran Ran, Shaomin LiuAbstract:Abstract Robust oxygen permeable ceramic membranes have potential applications in clean energy industries like oxyfuel power plants and green chemical synthesis like syngas production combining the separation and reaction in one unit. The well-known and highly permeable perovskite oxide membranes are limited by their lower chemical stability. In this work, a novel dual-phase hollow fiber membrane based on a fluorite Pr 0.1 Gd 0.1 Ce 0.8 O 2−δ (PCGO) and a spinel CoFe 2 O 4 (CFO) composite was developed via a phased inversion/sintering method. Enhanced oxygen permeability and unprecedented high CO 2 resistance were realized by the 50 wt%PCGO–50 wt%CFO dual-phase hollow fiber membrane. The composite was synthesized via a one-pot sol-gel preparation method to achieve the homogenous distribution and the formation of percolative network of each phase for both oxygen ionic and electronic conduction purpose. The oxygen permeation Flux of 0.54 mL min −1 cm −2 was achieved using He as sweep gas at 1000 °C. Membrane performance was further improved by coating a perovskite Ba 0.5 Sr 0.5 Co 0.8 Fe 0.2 O 3− δ (BSCF) layer on the outside surface of the dual phase membrane to face the feed gas-air leaving the other membrane side untouched to maintain its high stability to withstand the harsh gas condition containing CO 2 . The dual phase membrane had been successfully opeRated at 950 °C in pure CO 2 atmosphere for more than 200 h with Flux Rate fixed at 0.40 mL min −1 cm −2 without any noticeable performance degradation or membrane deterioration. By contrast, the Flux Rate of pure perovskite membrane had been sharply dropped down by 80% albeit opeRated for only 8 h.

manufacture of low lactose concentRated ultrafiltered diafiltered retentate from buffalo milk and skim milk
Journal of Food Science and Technology-mysore, 2014Co-Authors: Puneet Solanki, Vijay Kumar GuptaAbstract:Lactose concentration was reduced by 68.64 and 74.64 % in buffalo milk and skim milk by their respective 3.05 fold and 4.4 fold UF-DF concentration. The maximum UF-DF concentration of buffalo milk to 66.65 % volume reduction was observed as compared to 74.35 % volume reduction in buffalo skim milk. Average initial permeate Flux Rate of buffalo milk (42.86 l/h/m2) was much lower than skim milk (71.43 l/h/m2), which dropped to 2.86 and 5.95 l/h/m2 during UF-DF concentration. The initial permeate Flux Rate of homogenized buffalo milk (26.79 l/h/m2) was comparatively lower than that of buffalo milk which dropped to 2.38 l/h/m2 after 66.33 % volume reduction and 3.02 fold UF-DF concentration.
