  • solar driven adsorption desalination system
    Energy Procedia, 2014
    Co-Authors: S Mitra, Kandadai Srinivasa, S. S. Murthy, Pramod Kuma, P. Dutta
    Abstract:

    Desalination is one of the most traditional Processes to generate potable water. With the rise in demand for potable water and paucity of fresh water resources, this Process has gained special importance. Conventional thermal desalination Processes involves evaporative methods such as multi-stage flash and solar distils, which are found to be energy intensive, whereas reverse osmosis based systems have high operating and maintenance costs. The present work describes the Adsorption Desalination (AD) system, which is an Emerging Process of thermal desalination cum refrigeration capable of utilizing low grade heat easily obtainable from even non-concentrating type solar collectors. The system employs a combination of flash evaporation and thermal compression to generate cooling and desalinated water. The current study analyses the system dynamics of a 4-bed single stage silica-gel plus water based AD system. A lumped model is developed using conservation of energy and mass coupled with the kinetics of adsorption/desorption Process. The constitutive equations for the system components viz. evaporator, adsorber and condenser, are solved and the performance of the system is evaluated for a single stage AD system at various condenser temperatures and cycle times to determine optimum operating conditions required for desalination and cooling.

  • hyperspectral imaging an Emerging Process analytical tool for food quality and safety control
    Trends in Food Science and Technology, 2007
    Co-Authors: Aoife Gowen, Colm P Odonnell, P J Cullen, Gerard Downey, Jesus M Frias
    Abstract:

    Hyperspectral imaging (HSI) is an Emerging platform technology that integrates conventional imaging and spectroscopy to attain both spatial and spectral information from an object. Although HSI was originally developed for remote sensing, it has recently emerged as a powerful Process analytical tool for non-destructive food analysis. This paper provides an introduction to hyperspectral imaging: HSI equipment, image acquisition and Processing are described; current limitations and likely future applications are discussed. In addition, recent advances in the application of HSI to food safety and quality assessment are reviewed, such as contaminant detection, defect identification, constituent analysis and quality evaluation.
