1. 1. Theoretical Considerations and Experimental Observations on Heat Transfer in Hydrogen Direct Reduced Iron

   Master-uppsats, KTH/Materialvetenskap

   Författare :Felix Göttfert; [2023]
   Nyckelord :Hydrogen Direct Reduced Iron H-DRI ; Hydrogen Hot Briquetted Iron H-HBI ; Heat Transfer; Thermal Conductivity; Thermophysical Properties; Hydrogen Direct Reduced Iron H-DRI ; Hydrogen Hot Briquetted Iron H-HBI ; Värmeöverföring; Termisk konduktivitet; Termofysiska egenskaper;

   Sammanfattning : Steel has played an indispensable role in shaping our contemporary world  and will persist to play that role for the foreseeable future. However, the steel industry currently is responsible for 7% of the global CO2-emissions, primarily due to the conventional carbon-based reduction process of iron ore. LÄS MER

3. 2. Numerisk modellering av tvåfasströmning och syretransport i bubbelkolumner : Metodutveckling för att förutsäga syretransportshastigheten i rent vatten och surfaktantlösningar

   Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Författare :Fredrik Andersson; [2022]
   Nyckelord :Bubbelströmning; bottenluftning; syresättning; surfaktanter; computational fluid dynamics;

   Sammanfattning : I samband med det globala samhällets ökande populationsmängd och ekonomiska utveckling ökar färskvattenkonsumtionen och mängden avloppsvatten som produceras. Avloppsvatten behöver renas innan det släpps ut för att inte påverka miljön negativt. LÄS MER

4. 3. Technoeconomic analysis of T7 RNA polymerase manufacturing in E.coli for South Africa

   Master-uppsats, Lunds universitet/Kemiteknik (CI)

   Författare :Alicia Lundh; [2022]
   Nyckelord :T7 RNA polymerase; enzyme manufacturing; mRNA vaccine manufacturing; chemical engineering; Technology and Engineering;

   Sammanfattning : The enzyme, T7 RNA polymerase (T7 RNAP), is one of the most expensive raw materials required for mRNA vaccine production. As part of establishing South African manufacturing of mRNA vaccine, it is of interest to investigate the feasibility and profitability of South African manufacturing of T7 RNAP. LÄS MER

5. 4. Construction and Validation of a Lab-scaleBorehole Thermal Energy Storage Model

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Haoyang Dong; [2022]
   Nyckelord :borehole heat exchanger; lab-scale model; experimental construction; experiment test; validation; borrhålsvärmeväxlare; labbmodell; experimentell konstruktion; experimenttest; validering;

   Sammanfattning : Borehole heat exchangers are widely used in heat pumps of residential buildings and industrialsystems. It is known as one of the most energy ecient technologies which provides heatingand cooling by using sustainable geothermal energy. The life time of borehole heat exchangerslasts more than 50 years which is longer than combustion boilers. LÄS MER

7. 5. Effectiveness of Barrier Well by Pumping Ratio Control for Saltwater Intrusion: Lab-Scale Experiments and Numerical Modeling

   Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Författare :Shinichi Ozaki; [2021]
   Nyckelord :Saltwater intrusion; Barrier well; Pumping ratio control; Production well; salinity-affected coastal aquifer; Critical groundwater pumping ratio; Technology and Engineering;

   Sammanfattning : Saltwater intrusion is the most challenging problem in coastal regions. To prevent saltwater intrusion, saltwater pumping from a barrier well is widely applied, which is a direct abstraction of intruded saltwater from a coastal aquifer. Owing to its easy installation, many studies have been carried out. LÄS MER
