1. 6. Production assurance : concept, implementation and improvement

   Författare :Javad Barabady; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance;

   Sammanfattning : The dynamic business environment is characterized by short-term and long- term uncertainties in the business processes, combined with a short-term focus on meeting customers' and share-holders' requirements. Therefore, making correct decisions in a dynamic business environ-ment is a major challenge for production plant engineers and managers all over the world. LÄS MER

3. 7. Ethanol from woodCellulase enzyme production

   Författare :Zsolt Szengyel; Avdelningen för kemiteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; FPA measurement; acetic acid; furfural; non-volatile; volatile; inhibition; pH; carbon source; liquid; solid; softwood; hardwood; cellulases; production; Kemiteknik och kemisk teknologi; Biotechnology; Bioteknik;

   Sammanfattning : Conversion of biomass to liquid fuels, such as ethanol, has been investigated during the past decades. First due to the oil crisis of the 1970s and lately because of concerns about greenhouse effect, ethanol has been found to be a suitable substitute for gasoline in transportation. LÄS MER

4. 8. Depletion and decline curve analysis in crude oil production

   Författare :Mikael Höök; Kjell Aleklett; Roger Bentley; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; depletion rate; decline curve analysis; crude oil production; Other earth sciences; Övrig geovetenskap; Mathematical physics; Matematisk fysik; Other engineering physics; Övrig teknisk fysik; Physics with specialization in Global Energy Resources; Fysik med inriktning mot globala energiresurser;

   Sammanfattning : Oil is the black blood that runs through the veins of the modern global energy system. While being the dominant source of energy, oil has also brought wealth and power to the western world. Future supply for oil is unsure or even expected to decrease due to limitations imposed by peak oil. Energy is fundamental to all parts of society. LÄS MER

5. 9. Petroleum Production and Exploration : Approaching the End of Cheap Oil with Bottom-Up Modeling

   Författare :Kristofer Jakobsson; Kjell Aleklett; Roger Bezdek; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The theme of this thesis is the depletion of petroleum (crude oil and natural gas). Are there reasons to be concerned about an ‘end of cheap oil’ in the near future? There is a lively debate regarding this issue. The debate is sometimes described as a clash of ‘concerned’ natural scientists and ‘unconcerned’ economists. LÄS MER

7. 10. Mine production index: Development and application

   Författare :Amol Lanke; Javad Barabady; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Production Assurance program PAP ; Fuzzy analytical hierarchy process FAHP ; Mine production assurance MPA ; Bottleneck detection; Mine production index MPi ; Mining; Drift och underhållsteknik; Operation and Maintenance Engineering;

   Sammanfattning : Assuring production forms a crucial part of mining business profitability. Factors related to various mine operations, activities and business processes can threaten required/planned mine production. To address problems and ensure production level in mining, it is necessary to implement a mine production assurance program (MPA). LÄS MER
