1. Electrification in Process Industry - The Role of Process Integration and Future Energy Market Conditions
Sammanfattning : Electrification of industrial processes is a frequently discussed strategy to reduce greenhouse gas emissions from energy-intensive process industries and is highlighted in many roadmap studies. Electricity is a versatile energy carrier that enables a broad variety of options in which existing process unit operations are replaced with electricity-driven alternatives. LÄS MER
2. System studies of different CO2 mitigation options in the oil refining industry: Post-combustion CO2 capture and biomass gasification
Sammanfattning : To reach the objective endorsed by the EU Council for reducing EU greenhouse gas (GHG) emissions by 80-90% compared to 1990 levels by 2050, extensive cuts are necessary in all sectors. The oil refining sector is a major energy user and thus a major GHG emitter. LÄS MER
3. Excess heat utilisation in oil refineries - CCS and algae-based biofuels
Sammanfattning : 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. LÄS MER
4. Slurry Hydrotreatment of Biomass Materials over Metal Sulfide-based Supported and Unsupported Catalysts
Sammanfattning : The scarcity of fossil feedstocks and the deterioration of the current global climate condition have prompted the search for reliable alternatives for fossil fuel replacement. Biomass feedstocks are abundant, carbon-rich, and renewable bioresources that can be used to produce renewable bio-oils that can fill the gap left by fossil-derived oils. LÄS MER
5. Partial CO2 capture to facilitate cost-efficient deployment of carbon capture and storage in process industries - Deliberations on process design, heat integration, and carbon allocation
Sammanfattning : Climate change requires that all energy-related sectors reduce drastically their greenhouse gas (GHG) emissions, at a global rate of 1–2 GtCO2 per year, starting now. Process industries, such as the iron and steel, cement, petrochemical, and oil-refining industries, are inherently carbon-intensive, and carbon capture and storage (CCS) is one of the few options available to achieve the required deep reductions in carbon dioxide (CO2) emissions.
