  1. 1. Experimental Studies on CO2 Capture Using Absorbent in a Polypropylene Hollow Fiber Membrane Contactor

    Detta är en avhandling från Västerås : Mälardalen University

    Författare :Yuexia Lu; Mälardalens högskola.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2 capture; Simultaneous removal of CO2 and SO2; Hollow fiber membrane contactor; Membrane gas absorption; Partial wetting; Surface modification; CO2-avskiljning; samtidig avskiljning av CO2 och SO2; ihålig fiber; membran; gas absorption; vätning; ytmodifiering; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : In recent years, membrane gas absorption technology has been considered as one of the promising alternatives to conventional techniques for CO2 capture due to its favorable mass transfer performance. As a hybrid approach of chemical absorption and membrane separation, it exhibits a number of advantages, such as operational flexibility, compact structure, high surface-area-to-volume ratio, linear scale up, modularity and predictable performance.

  2. 2. Antimicrobials in sewage treatment plants occurrence, fate and resistance

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Marcus Östman; Umeå universitet.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biocides; antibiotics; sewage treatment plants; wastewater; sludge; ozonation; activated carbon; antibiotic resistance; antimicrobials; mass flows; LC-MS MS; environment; advanced water treatment;

    Sammanfattning : The World Health Organization (WHO) has identified antibiotic resistance as a major threat to human health. The environment has been suggested to play an important role in the emergence of antibiotic resistant bacteria. The external environment can act as a source of resistance genes that could potentially be transferred into human pathogens. LÄS MER

  3. 3. Impacts of Thermo-Physical Properties on Chemical Absorption for CO2 Capture

    Detta är en avhandling från Västerås : Mälardalen University Press

    Författare :Worrada Nookuea; Mälardalens högskola.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : Following the climate change mitigation target in Paris agreement, the global warming has to be limited to 2.0°C above the preindustrial levels. One of the potential methods is carbon capture and storage (CCS), which can significantly reduce the CO2 emissions from the vast point sources such as power plants, industries, and natural gas processes.
