11. Process Optimization of UV-Based Advanced Oxidation Processes in VOC Removal Applications
Sammanfattning : Air pollution is a major concern in developed countries due to its hazardous health effects. Recent studies by the WHO (World Health Organization) estimate that urban air pollution causes a number of diseases of the respiratory tract and is associated with 150,000 deaths each year. LÄS MER
12. Bio-refinery system integrated with pulp and paper mills using black liquor gasification
Sammanfattning : Mitigation of climate change and energy security are major driving forces for increased biomass energy utilization. The pulp and paper industry consumes a large proportion of biomass worldwide that include bark, wood residues, and black liquor. LÄS MER
13. In pursuit of clean air through numerical simulations of no-waste pollutant removal
Sammanfattning : As epidemiological evidence continues to mount, it has become undeniable that exposure to high levels of airborne pollutants such as SOx and NOx are detrimental to human health. In recent years, millions of premature deaths by stroke, coronary heart disease, and lung cancer worldwide have been linked to poor outdoor air quality. LÄS MER
14. Biomass gasification in ABFB : Tar mitigation
Sammanfattning : Biomass gasification may be an attractive alternative for meeting future energy demand. Although gasification is a mature technology, it has yet to be fully commercialised due to tar formation. This study focuses on the tar mitigation in gas produced in an atmospheric bubbling fluidised bed (ABFB) gasification system. LÄS MER
