  1. 1. Determining the quality of natural gas and biomethane : Development of a correlative method and instrument prototype for measuring gas quality

    Author : Taras Koturbash; Vladimir G. Kutcherov; Andrew R. Martin; Khaled Loubar; KTH; []
    Keywords : Natural gas; biomethane; calorific value; Wobbe Index; ultrasonic measurement; sound attenuation; Energy Technology; Energiteknik;

    Abstract : The composition of natural gas highly depends on its origin: natural gas from various deposits, substitute natural gas that can be produced from fossil fuels or renewable sources. The intermixing of gases from various supply sources during pipeline transportation also leads to more complicated and unpredictable gas composition variations at the consumption site. READ MORE

  2. 2. Production from Giant Gas Fields in Norway and Russia and Subsequent Implications for European Energy Security

    Author : Bengt Söderbergh; Kjell Aleklett; Roger Bentley; Uppsala universitet; []
    Keywords : natural gas production; giant gas fields; depletion rate; forecasting; energy security; EU; Norway; Russia;

    Abstract : The International Energy Agency (IEA) expects total natural gas output in the EU to decrease from 216 billion cubic meters per year (bcm/year) in 2006 to 90 bcm/year in 2030. For the same period, EU demand for natural gas is forecast to increase rapidly. In 2006 demand for natural gas in the EU amounted to 532 bcm/year. READ MORE

  3. 3. Burst Detection and Location in Pipelines and Pipe Networks - With Application in Water Distribution

    Author : Dalius Misiunas; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Sudden pipe bursts occur in high-pressure water transmission pipelines and water distribution networks. The consequences of these bursts can be very expensive due to the outage time while the burst pipe is repaired, the cost of repair, and damage to surrounding property and infrastructure. READ MORE

  4. 4. Total internal reflection ellipsometry

    Author : Michal Poksinski; Uwe´ Beck; Linköpings universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : This thesis summarizes the work performed on the development and implementation of the optical measurement technique called total internal reflection ellipsometry (TIRE).The TIRE principle is based on spectroscopic ellipsometry performed under conditions of total internal reflection.

  5. 5. Strategies, Methods and Tools for Solving Long-term Transmission Expansion Planning in Large-scale Power Systems

    Author : Desta Zahlay Fitiwi; Lennart Söder; Michel Rivier; Fernando de Cuadra; Andres Ramos; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transmission expansion planning; uncertainty and variability; optimization; stochastic programming; moments technique; clustering; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Driven by a number of factors, the electric power industry is expected to undergo a paradigm shift with a considerably increased level of variable energy sources. A significant integration of such sources requires heavy transmission investments over geographically wide and large-scale networks. READ MORE
