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

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

   Abstract : 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. READ MORE

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

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

   Abstract : 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. READ MORE

5. 3. A study of ethylene production via the 2-oxoglutarate dependent pathway in S. cerevisiae

   Author : Nina Johansson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ethylene forming enzyme; Ethylene; respiration rate; Saccharomyces cerevisiae; cultivation; production; nitrogen metabolism; 2-oxoglutarate; enzyme engineering; metabolic modeling;

   Abstract : The detrimental effect of the petroleum industry on the environment combined with the threat of peak oil has driven the exploration for alternative strategies to produce traditional petrochemicals. Biotechnological production could be an alternative, using microorganisms to convert renewable feedstocks into desired products. READ MORE

6. 4. Atomic Scale Modelling in Photoelectrocatalysis : Towards the Development of Efficient Materials for Solar Fuel Production

   Author : Giane B. Damas; Carlos Moyses Araujo; Rajeev Ahuja; Clas Persson; Uppsala universitet; []

   Abstract : Using sunlight to produce valuable chemicals has been pointed out as an interesting alternative to deal with the well-known environmental problem related to the use of fossil fuels for energy generation. Thus, it is crucial for this field the development of novel photocatalysts that could drive the uphill reactions with high efficiency while presenting low price and toxicity. READ MORE

7. 5. Energy savings for petroleum processing : Using mathematical models, optimal control and diagnostics

   Author : Esin Iplik; Konstantinos Kyprianidis; Ioanna Aslanidou; Mehmet Mercangöz; Mälardalens universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

   Abstract : Petroleum products are widely used as an energy supply, and the total production capacity of petroleum refineries is quite high. In this thesis, an energy intensive refinery process, hydroprocessing, is selected and evaluated in terms of its energy loss contributors. Digital solutions are discussed and demonstrated to reduce losses. READ MORE
