  • Exergy analyses of the biochemical processes of photosynthesis

    This paper gives the exergy analyses of the main biochemical processes of photosynthesis in green plants. In the light reactions, photosystem I, photosystem II, and ATP-synthesis are found to operate at exergy efficiencies of 50%, 68% and 81%, respectively, so that 48% of the exergy of directly utilised solar photons is converted to biochemical energy carriers. Subsequently, in the dark ...

  • The Rationale for Accelerating Regionally Focused Climate Intervention Research

    Abstract Ten years ago, Paul Crutzen asked whether the time had come to consider undertaking research into intentionally intervening in the climate system so that it might be considered a policy option comparable to reducing emissions for limiting human-induced climate change. Crutzen’s article pointed out how little progress had been made in reducing emissions and suggested that ...

  • Energy and exergy analyses of vacuum drying process of pine timbers

    In this study, an experimental system for the vacuum drying of timbers is designed. Experiments in the different temperature, pressure and the residence time in vacuum are carried out. The drying experiments are conducted at three different drying temperatures varied between 40°C and 60°C. The drying experiments are conducted at three different pressures varied between 60 kPa and 80 kPa. The ...

  • Energy and exergy analyses of a steam reforming process for hydrogen production

    Hydrocarbon steam reforming is an important process for hydrogen production. In petroleum refineries, steam reforming is most commonly used for hydrogen production from naphtha and light hydrocarbon gases (methane, ethane and propane). Since the hydrocarbon steam reforming system is one of the highest energy intensive systems in a petroleum refinery it should be directed to a more efficient use ...

  • Energy and exergy analyses in a thermal process of a production line for a cement factory and applications

    The objective of this study is to determine the actual energy losses by performing energy and exergy analyses and to evaluate energy and exergy efficiency in each process for the cement factory. In these analyses, for each process energy and exergy diagrams have been constituted on the production line. Efficiencies (energy/exergetic) of the processes for the raw mill, the rotary kiln, the trass ...

  • Analysers and next generation SRU control

    The history of on-line process analytics is a relatively short one. Development was driven by the need for process control of high value hydrocarbonbased products. The first on-line analyser applications came during the second war. Rapid development came in the 1970s with the advent of the microprocessor and resultant chemometric techniques. Led by Phillips Petroleum, Union Carbide and Dupont ...

  • Analysing four of the most contaminated foodstuffs

    Food adulteration has been around since the Victorian times when cheese was often coloured with lead salts, beer and milk were watered down and flour was bulked out with chalk dust or ground bones [1]. Governments apply stringent legislation and quality standards to food products but the practice of adulteration, driven by greed and profit, is still seen. ...

  • Comparing modelling techniques for analysing urban pluvial flooding

    Short peak rainfall intensities cause sewer systems to overflow leading to flooding of streets and houses. Due to climate change and densification of urban areas, this is expected to occur more often in the future. Hence, next to their minor (i.e. sewer) system, municipalities have to analyse their major (i.e. surface) system in order to anticipate urban flooding during extreme rainfall. Urban ...

  • The technology-component matrix: a tool for analysing and managing knowledge

    Previous studies have shown that knowledge creation is becoming a core competency, and technology issues have to be incorporated into corporate strategy in a new way. However, there is a lack of an appropriate framework which would allow practitioners to trace the value migration among different types of technology. This paper, by introducing an innovative technology-component matrix, aims to ...

  • Energy and exergy analyses of a spark-ignition engine

    In this paper, the performance of an internal combustion engine is evaluated at the steady-state condition by application of energy and exergy analysis using the experimental test results. The energy and exergy balances are calculated at different engine speeds. The results show that the heat rejection of energy and exergy flow increases with increasing engine speed. The exergy efficiencies are ...
