  3. 2. On-Line Monitoring Applications in Nuclear Power Plants

    Författare :Hashem Mehrdad Hashemian; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; calibration monitoring; noise analysis; instrumentation and control; sensing line blockages; Nuclear power plants; sensor response time testing; reactor diagnostics; next generation reactors; applied research;

    Sammanfattning : As the current generation of nuclear power plants have passed their mid-life, increased monitoring of their health is critical to their safe operation. This is especially true now that license renewal of nuclear power plants has accelerated, allowing some plants to operate up to 60 years or more. LÄS MER

  4. 3. Intensification of the biogas process by improved process monitoring and biomass retention

    Författare :Lovisa Björnsson; Miljö- och energisystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BOD; hydrogen; on-line; monitoring; biofilm; anaerobic digestion; biogas; Biotechnology; Bioteknik;

    Sammanfattning : The utilisation of energy in the form of biogas is one of the environmentally sound alternatives available using renewable energy sources. Biogas is formed by anaerobic degradation of organic material, the main consistuent being energy-rich methane. LÄS MER

  5. 4. Novel on-line mid infrared detection strategies in capillary electrophoretic systems

    Författare :Malin Kölhed; Bo Karlberg; Sven P. Jacobsson; Andre' J. Sommer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; on-line hyphenation; mid infrared detection; capillary electrophoresis; FTIR; quantum cascade laser; aqueous samples; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Infrared absorption spectra can provide analytically useful information on a large variety of compounds, ranging from small ions to large biological molecules. In fact, all analytes that possess a dipole moment that changes during vibration are infrared-active. The infrared (IR) spectrum can be subdivided into far-, mid- and near- regions. LÄS MER

  7. 5. Sensor Systems for Bioprocess Monitoring

    Författare :Helena Lidén; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; on-line; pattern recognition; gas sensor array; electronic nose; monosaccharides; ethanol; biosensor; carbon paste electrode; Analytical chemistry; Analytisk kemi;

    Sammanfattning : Two different detection methods for on-line monitoring of substrates and products in ethanol fermentations have been studied. Amperometric biosensors were developed for use as detectors in flow injection or liquid chromatographic (LC) systems. LÄS MER
