  • Energy and exergy analyses of a combined ammonia-fed solid oxide fuel cell system for vehicular applications
    International Journal of Hydrogen Energy, 2011
    Co-Authors: Ehsan Baniasadi, Ibrahim Dincer
    Abstract:

    Abstract In this study, both energetic and exergetic performances of a combined heat and power (CHP) system for vehicular applications are evaluated. This system proposes ammonia-fed solid oxide fuel cells based on proton conducting electrolyte (SOFC-H+) with a heat Recovery Option. Fuel consumption of combined fuel cell and energy storage system is investigated for several cases. The performance of the portable SOFC system is studied in a wide range of the cell’s average current densities and fuel utilization ratios. Considering a heat Recovery Option, the system exergy efficiency is calculated to be 60–90% as a function of current density, whereas energy efficiency varies between 60 and 40%, respectively. The largest exergy destructions take place in the SOFC stack, micro-turbine, and first heat exchanger. The entropy generation rate in the CHP system shows a 25% decrease for every 100 °C increase in average operating temperature.

  • ETFA - Order/remanufacturing policy of spare part with Recovery Option for stochastic deteriorating system
    2013 IEEE 18th Conference on Emerging Technologies & Factory Automation (ETFA), 2013
    Co-Authors: H. Boudhar, M. Dahane, N. Rezg
    Abstract:

    This article discusses the issue of spare part return in a production system with a single machine subject to a monotone and stochastic deterioration. It investigates the problem of the spare parts returns and the reusing problem of recovered part, with or without remanufacturing actions. Each recovered spare part is stocked, before being inspected and probably reused. We propose an order/remanufacturing replacement policy with an inventory management of the recovered spare parts. A condition-based maintenance policy is adopted with three decision thresholds for order management, preventive maintenance management and corrective maintenance. A genetic algorithm based approach is proposed and an illustrative example is presented to reveal the application of the proposed policy.

  • Energy Recovery in the sustainable recycling of plastics from end-of-life electrical and electronic products
    Proceedings of the 2005 IEEE International Symposium on Electronics and the Environment 2005., 2005
    Co-Authors: M.m. Fisher, F.e. Mark, T. Kingsbury, J. Vehlow, T. Yamawaki
    Abstract:

    As the collection of end-of-life (EOL) electrical and electronic products from households and businesses increases around the world, the search for economically and environmentally responsible and sustainable Recovery and recycling processes intensifies. Since the early 1990s, the global plastics industry has been at the forefront of research, development, and demonstration projects to ensure that sound integrated resource management Options exist for plastics. Regional trade associations such as the American Plastics Council (APC), Plastics Europe (previously the Association of Plastics Manufacturers in Europe or APME), and the Plastics Waste Management Institute of Japan (PWMI) have led much of this effort. Mechanical recycling, feedstock chemical recycling, fuel Recovery, and energy Recovery technologies have all been significantly advanced through this work. This paper provides an overview of the energy Recovery Option, which is an important, albeit partial component of this portfolio of resource Recovery Options. Available in all regions today, energy Recovery processes is an important part of the environmentally and economically sound resource Recovery infrastructure for plastics from EOL electrical and electronic equipment (EEE). A significant body of research is summarized that demonstrates that energy Recovery not only contributes to reduced fossil fuel consumption by society, but provides an ecologically sound way to manage a significant portion of the plastics from today's EOL EEE.
