Technical and Economical Feasibility of zeolite NaA membrane-based reactors in liquid-phase etherification reactions
Chemical Engineering and Processing: Process Intensification, 2009Co-Authors: M. Pera-titus, J. Llorens, F. CunillAbstract:This paper describes the pervaporation performance of film-like zeolite NaA membranes synthesized in our laboratory by template-free seeded hydrothermal towards the dehydration of n-pentanol/water and n-pentanol/water/DNPE mixtures (DNPE=di-n-pentyl ether, C10H22O). DNPE is a linear symmetric ether that can be used as blending additive in reformulated diesel fuels and that can be produced from C-4 feedstocks via n-pentanol, obtained in its turn by selective hydroformylation of linear butenes. The membranes showed selectivities up to 3000 in the dehydration of n-pentanol/water binary mixtures, and water/DNPE and n-pentanol/DNPE selectivities approaching infinity (i.e. DNPE does not pervaporate) in the dehydration of n-pentanol/water/DNPE ternary mixtures. On the basis of the separation results presented in this work, and using experimental reaction kinetics data, we discuss the Feasibility of zeolite NaA membrane reactors to carry out the liquid-phase etherification reaction of n-pentanol to di-n-pentyl ether(DNPE) catalyzed by ion-exchange sulfonated resins. These catalysts suffer from strong deactivation in the progress of the reaction due to the generation of water. (C) 2009 Elsevier B.V. All rights reserved.

Feasibility of thermal energy storage systems in an institutional building in subtropical climates in Australia
Applied Thermal Engineering, 2011Co-Authors: Mustafizur Rahman, Mohammad. Rasul, Mohammad Masud Kamal. KhanAbstract:Abstract Thermal energy storage is (TES) a preferred demand side management (DSM) technology for shifting cooling load demand from peak hour to off-peak hour in the heating, ventilating and air conditioning (HVAC) industry. In this study, the technical and Economical Feasibility of introducing TES systems in a building in subtropical Central Queensland (Australia) is presented. Firstly, the cooling load profile of existing systems is simulated using building simulation software DesignBuilder (DB) and verified with on-site measured data. Then, using the verified simulation technique, the technical and Economical Feasibility of TES systems are analysed for both full and partial storage scenarios. The results show that the full and partial chilled storage systems can save up to 61.19% and 50.26% respectively of the electricity cost required for cooling when compared with the conventional system in subtropical climate.

energy conservation in buildings cogeneration and cogeneration coupled with thermal energy storage
Applied Energy, 2004Co-Authors: K H Khan, M G Rasul, M M K KhanAbstract:Energy-conservation opportunity in an institutional building is studied through cogeneration with double-effect absorption chiller. Both, technical and Economical Feasibility is evaluated and presented. The typical electrical energy and cooling-load demand profiles of the buildings concerned are determined. Payback period, internal rate-of-return (IRR), net present value (NPV) and net profit of the Institute is determined through cash-flow analysis. Then, cogeneration coupling with thermal energy storage (TES) is studied and its technical and Economical Feasibility is evaluated and compared with that of cogeneration. On-site cogeneration with a double-effect absorption chiller provides a potential of at least 13% peak-demand reduction and about a 16% savings in energy consumption. It provides IRR greater than 21% but the saving potential is limited by the low demand of co-generated chilled water within the community of the Institution. Cogeneration coupling with thermal energy storage offers a simple and Economically more attractive approach for maximizing the utilization of co-generated chilled-water and shows 23% reduction in peak demand and a 21% savings in energy consumption. It provides a higher IRR, greater than 25%.
