    Nyckelord :biological methanation; biogas upgrade; methane; small-scale methanation;

    Sammanfattning : In the present study, the concept of a biological H2 methanation (BHM) system was created for four cases of scale which are determined by electrolyser scale. The system design is aimed to upgrade existing biogas to vehicle fuel quality, with a concentration of CH4 above 95% and H2S removal. The cases of scale and type of electrolyser are: 4. LÄS MER

  4. 3. Evaluation of Current and Feasible Future Use of Geothermal Energy at Chinyunyu Hot Spring, Zambia

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Christopher Kapasa; [2014]
    Nyckelord :;

    Sammanfattning : The main source of geothermal energy is the heat flow from the mantle beneath the Earth’s surface, generated by the gradual decay of radioactive isotopes in the Earth‘s crust. A hot spring is produced by the emergence of geothermally heated groundwater flowing out to the Earth’s surface. LÄS MER
