  • CFD-based optimization and design of multi-channel Inorganic Membrane tubes
    2016
    Co-Authors: Yang Zhao, Cheng Jingcai, Yang Chao, Liang Bin
    Abstract:

    As a major configuration of Membrane elements, multi-channel Porous Inorganic Membrane tubes were studied by means of theoretical analysis and simulation. Configuration optimization of a cylindrical 37-channel Porous Inorganic Membrane tube was studied by increasing Membrane filtration area and increasing permeation efficiency of inner channels. An optimal ratio of the channel diameter to the inter-channel distance was proposed so as to increase the total Membrane filtration area of the Membrane tube. The three-dimensional computational fluid dynamics (CFD) simulation was conducted to study the cross-flow permeation flow of pure water in the 37-channel ceramic Membrane tube. A model combining Navier–Stokes equation with Darcy's law and the Porous jump boundary conditions was applied. The relationship between permeation efficiency and channel locations, and the method for increasing the permeation efficiency of inner channels were proposed. Some novel multi-channel Membrane configurations with more permeate side channels were put forward and evaluated

  • a review on the latest development of carbon Membranes for gas separation
    Journal of Membrane Science, 2001
    Co-Authors: Ahmad Fauzi Ismail, L I B David
    Abstract:

    Inorganic Membranes have been developed before 1945. The earlier application of Inorganic Membranes was primarily concentrate on military purpose. Carbon Membrane is one type of Porous Inorganic Membrane. Although the concept of carbon Membrane for gas separation has been found in the early 1970, the interest to develop carbon Membrane only increased, since Koresh and Soffer successfully prepared apparently crack-free molecular sieving hollow fiber carbon Membranes. Nowadays, plenty of researchers have used different polymeric materials; including polyimides, to prepare carbon Membranes by using pyrolysis. In general, carbon Membranes can be divided into four major configurations: flat sheet, Membrane supported on tube, capillary, and hollow fiber. Permeation properties of carbon Membranes have been improved greatly in these 20 years. Carbon Membranes offer advantages over polymeric Membranes especially in terms of selectivity as well as thermal and chemical stability. More attention will be paid to carbon Membranes in this century. This paper will review the development of carbon Membranes in the last 30 years and give a clear future direction in research for carbon Membrane.

  • Lanthanum-doped kaolinite for hierarchical bi-modal Porous Inorganic Membrane
    Journal of the European Ceramic Society, 2017
    Co-Authors: Xinwei Chen, Suan Yong Eddie Yeo, Jia Yi Idris Woo, Yi’en Zhou, Liang Hong
    Abstract:

    Abstract Porous Inorganic Membranes can function in corrosive or high-temperature environments for prolonged duration without significant degradation in performance. Their high fabrication and material cost, however, outweigh their advantages. Here, adding lanthanum (La) to kaolinite, a cheaper Inorganic material, enables a stronger and more permeable Membrane sintered at 1150 °C; A 11 wt% La-doped kaolinite displays strength of ∼10 MPa and Darcy’s permeability of 1.5 × 10 −13  m 2 –2.5 and 3 times higher than the pristine sintered kaolinite matrix respectively. The La-doping technique disrupts the randomly oriented stack of kaolinite flakes and increases the particle-particle contacts during sintering. Consequently, “pot-holes” are created to give a bi-modal Porous structure, which reduces the tortuosity and improves the pore connectivity. It is concluded that La interacts with Al of the kaolinite during sintering based on XRD and EDX analysis. Finally, a carbon nanotube network (CNTN) is incorporated into the Porous channel of La-doped Membrane and is used as a Membrane to purify emulsified oily water with a 100% rejection.
