  1. 1. Modelling the Production of Biofuels via Olefins Oligomerisation

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Nima Mirzaei; [2020]
    Keywords : Biofuels; Mathematical Modelling; Process Simulation; Oligomerisation; Fischer-Tropsch; Biobränslen; Matematisk Modellering; Process Simulering; Oligomerisering; Fischer-Tropsch;

    Abstract : The technical feasibility of gasoline and diesel range hydrocarbons production through oligomerisation of olefins, starting from biomass with the intermediary steps of gasfication, water-gas shift reaction and syngas-to-olefins synthesis was investigated, through mathematical modelling and simulation on Matlab. The model for the gasifier was based on minimisation of Gibbs free energy and its results showed that higher carbon efficiencies could be achieved at lower pressures and steam inlet, and more inlet energy, by pre-heating the gasifying agents.

  3. 2. Crack propagation calculations in non-elastic metals

    University essay from Luleå tekniska universitet/Material- och solidmekanik

    Author : Máren Ingá Baer; [2018]
    Keywords : crack propagation; fracture mechanics;

    Abstract : It is important to know the lifespan of a component, thus services can be planed. At Siemens Industrial Turbomachinery AB (SIT AB) develop and produce gas and steam turbines, the turbines are heavily strained by thermal and centrifugal forces during their life span which lead to cracking.

  4. 3. Degradation mechanisms of UN and UN–10U3Si2 pellets of varying microstructure by comparative steam oxidation experiments

    University essay from KTH/Reaktorfysik

    Author : Selim Uygur; [2016]
    Keywords : Uranium Mononitride; Uranium Silicide; Composite; Steam degradation; corrosion mechanism;

    Abstract : During an extended LOCA in a LWR, the current UO2 fuel reaches very high temperatures and eventually melts, while the current Zircaloy fuel cladding oxidizes releasing hydrogen. These two consequences can lead to an unacceptable amount of radioactive release by presenting accident routes for containment failure. READ MORE

  5. 4. ECC-D4 Electostatic Oil Cleaner Design for Heavy-Duty Gas Turbine Applications

    University essay from Mekanisk värmeteori och strömningslära

    Author : Murat Gorur; [2010]
    Keywords : Energy System; Electrostatic Cleaner; Gas Turbines; Electrostatic Field; Turbine Oil; Oil Clenaer;

    Abstract : The turbine technology improvements from 1980 onwards have considerably increased mechanical and thermal stresses on turbine oils which, cause oil oxidation and thereby turbine oil degradation (Livingstone et al., 2007; Sasaki & Uchiyama, 2002). READ MORE
