2. 1. Towards sustainable water use in industry: a case study of the oil refinery industry in Kazakhstan

   Author : Ivan Radelyuk; Avdelningen för Teknisk vattenresurslära; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; industrial wastewater; oil refinery; Kazakhstan; groundwater contamination; groundwater modeling; contamination transport modeling; Sustainable water use; Environmental Impact Assessment; Circular Economy;

   Abstract : The concept of “Sustainable water use” (SWU) aims to assure three pillars of sustainability related to the water sector: the social, environmental, and economical. Industrial development, especially in developing countries, requires an adequate response, as industrial activities are recognized as one of the major sources of water pollution, what leads to deterioration of environmental safety and wellbeing of the society.

4. 2. Towards a Sustainable Biomass and Waste Refinery Based on Pyrolysis Combined with a Pretreatment Process

   Author : Yuming Wen; Weihong Yang; Pär Jönsson; Tobias Richards; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pyrolysis; anaerobic digestion; hydrothermal carbonization; refinery; biomass; waste; kinetics; LCA; Energiteknik; Energy Technology; Chemical Engineering; Kemiteknik;

   Abstract : Some of the naturally accumulated biomass and the massive production of waste by human activities have caused serious environmental problems. The degradation of biomass and waste is one of the main greenhouse gasses (GHG) emission sources. READ MORE

5. 3. Biological Treatment of Oily Sludge and Sediments

   Author : Mait Kriipsalu; Chalmers tekniska högskola; []
   Keywords : bioremediation; refinery; aerobic biotreatment; flocculation-flotation unit FFU ; petroleum hydrocarbons; oily sludge; static biopile; PAHs; sediments;

   Abstract : AbstractOily sludge, generated in refineries or in other industrial sectors, and oil-containing sediments, removed from water bodies during remediation works, pose an environmental problem. A common feature between both is their high water content, and variable content of organic and inorganic contaminants, which complicates their treatment. READ MORE

6. 4. Excess heat utilisation in oil refineries - CCS and algae-based biofuels

   Author : Viktor Andersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; techno-economic; CO2 emissions; carbon dioxide; renewable diesel; post-combustion; algae biofuels; process integration; GHG emissions; oil refining industry; carbon capture and storage CCS ;

   Abstract : The main objective of this thesis is to investigate two different concepts for CO2 mitigation, from a system perspective, in relation to the oil refining industry: CO2 capture and storage; and algae-based biofuels. For all these processes, process integration with an oil refinery is assumed. READ MORE

7. 5. Production scheduling and shipment planning at oil refineries : optimization based methods

   Author : Jan A. Persson; Bjørn Nygreen; Linköpings universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : In the oil refinery industry, companies need to have a high utilization of production, storage, and transportation resources to be competitive. This can only be achieved by proper planning The purpose of this thesis is to contribute to the development of optimization models and solution methods that support the scheduling and planning at refinery companies.
