  • operational experience of a solar membrane distillation Demonstration Plant in pozo izquierdo gran canaria island spain
    Desalination, 2012
    Co-Authors: Gemma R Raluy, R Schwantes, Vicente J Subiela, Baltasar Penate, Gustavo Melian, Juana Rosa Betancort
    Abstract:

    Abstract Desalination is a technology with a high energy demand, mainly supplied by fossil sources. Therefore, solar energy is a real alternative, as it supplies virtually unlimited energy. Solar desalination could be an ideal solution for isolated areas which receive high solar irradiation per day. Solar Membrane Distillation (MD) is a developing technology particularly interesting for small supplies, isolated populations and autonomous systems. As it is a low temperature operation process, MD is very suitable for integration with thermal solar systems and/or waste heat recovery units; in contrast to other desalination technologies, only a coarse filtration of the water is required as pretreatment. However, the commercial availability is currently quite limited. This paper presents the promising 5-year experience and data analysis of a solar compact MD Demonstration Plant installed in the facilities of the Instituto Tecnologico de Canarias (ITC) in Playa de Pozo Izquierdo (Gran Canary Island-Spain). The unit was designed and installed at the end of 2004 as part of a co-funded FP6 DGTREN research project called ‘Development of stand-alone, solar thermally driven and PV-supplied desalination systems based on innovative membrane distillation’ (MEMDIS) and has been continuously tested within the FP7 EU co-funded project called ‘MEmbrane DIstillation in Remote AreaS — MEDIRAS’.

  • Study of a Demonstration Plant for the co-composting of olive-oil-processing wastewater and solid residue
    Bioresource Technology, 1996
    Co-Authors: Apostolos Vlyssides, Dimitris L. Bouranis, Maria Loizidou, G. Karvouni
    Abstract:

    Abstract The co-composting of the solid residue and wastewaters from the olive-oil production process has been studied as a new method for the treatment of wastewater containing high organic and toxic pollutants. The experimental results for a Demonstration Plant using solid residue from olive extraction as bulking material and olive-oil-processing effluents as continuously fed wastewater are reported. Composting temperature was controlled between 45 and 65°C by air supply and the wastewater addition was fed mainly in order to keep the moisture in the range of 45 to 60% and secondly to replace the carbon substrate. During 23 days of operation in the thermophilic region, the system was fed with 263 m 3 wastewater in total, which means an average rate of 11.4 m 3 /day wastewater or 2.9 kg wastewater per kg solid residue. The total bioenergy production was estimated to be about 90 000 000 kcal. Then followed a 3 months stabilization period in the mesophilic region until the final product reached ambient temperature.

  • chemical looping combustion for power generation concept study for a 10 mwth Demonstration Plant
    International Journal of Greenhouse Gas Control, 2011
    Co-Authors: Klemens Marx, Tobias Pröll, Johannes Bolharnordenkampf, Hermann Hofbauer
    Abstract:

    Abstract A semi-commercial 10 MW th chemical looping combustion (CLC) Plant for power production is proposed as a next scale Demonstration Plant after successful operation of a 120 kW CLC pilot rig. The design criteria for the CLC boiler are derived from the experience obtained from the CLC pilot rig at Vienna University of Technology. The IPSEpro simulation environment is chosen for implementation of the process flow sheet of the CLC power Plant. A single pressure steam cycle is suggested for this small scale Demonstration Plant. Heat exchangers and a five-stage steam turbine are arranged. Basic design parameters of the power Plant are derived from detailed mass and energy investigations and discussed. It turns out that the net electric efficiency of such a small scale Plant can be expected to be in the range of 32.5–35.8%. However, a Demonstration of CLC at such a scale is necessary in order to gain confidence in more sophisticated CLC power generation concepts at larger scale.

  • Tidd PFBC Demonstration Plant operation and testing
    1993
    Co-Authors: M. Marrocco, D.r. Hafer
    Abstract:

    The Tidd PFBC Demonstration Plant, located in Brilliant, Ohio, is in its third year of operation and testing. The Plant has achieved many of its original performance goals and test objectives; however, current emissions standards and the projected performance of competing technologies have caused a reassessment of the program goals. This paper provides a review of PFBC technology and discusses project goals and milestones achieved. Emphasis is placed on environmental performance and on projected modifications to be undertaken to improve sulfur capture and reduce calcium/sulfur molar ratio. A large-scale hot gas clean up Demonstration is also in progress at Tidd. The Demonstration has been providing information on ceramic barrier filter technology since its commissioning in October 1992. The Tidd Plant has met both its performance guarantees for emissions and its environmental permit limits. However, the tightening of government environmental standards and the projected performance of competing technologies have required a reassessment of the goals of AEP`s PFBC program. Efforts are focusing on achieving better environmental performance, particularly with respect to sulfur capture and sorbent utilization.

  • Test results from the 70 MW Tidd PFBC Demonstration Plant
    1993
    Co-Authors: D.r. Hafer, M.j. Mudd, M.e. Zando
    Abstract:

    The 70 MWe Tidd PFBC Demonstration Plant in Brilliant, Ohio, the first PFBC Demonstration Plant in North America, is in its third year of operation and testing. Operation of the Tidd Plant has provided invaluable experience with the systems required to apply PFBC technology to electric power generation. It has also provided operating data to verify the ability of the PFBC process to achieve a high degree of sulfur removal and low NO{sub x} emissions when burning high-sulfur bituminous coal. This paper provides an update on the operating experience of the Tidd PFBC Demonstration Plant, reviews the lessons teamed with PFBC technology in the start-up and debugging of the PFBC systems, and provides data from the operation and performance tests conducted at the Tidd Plant.
