1. Purification of Volatile Organic Compounds in Channeled Ventilation Pipes at the Sysav Water Treatment Plant for Hazardous Waste
University essay from Lunds universitet/Kemiteknik (CI)Abstract : Several channeled emissions at the Sysav water treatment plant for hazardous waste as of December 2021 exceed permitted levels of unknown volatile organic compounds (VOCs) stated in the European Parliament councils’ directives 2010/75/EU. A range of possible treatment methods are briefly discussed before zeolite adsorption, and thermal regeneration followed by catalytic combustion is decided to be the method of greatest feasibility and is the subject of further investigation.

3. Epiphytic lichens associated with different traffic intensities along the highway E4
University essay from SLU/Dept. of EcologyAbstract : Inventories of epiphytic lichens on Scots pine (Pinus sylvestris) were conducted at three sites in east central Sweden: along the newly build motorway (Road E4), along the old road (Road 600) and in a reference site, to compare the effects of traffic pollution on lichen diversities. At each site, species richness, lichen mean sensitivity value (MK), air quality index of the forest stand/sample plot (LKI) and nitrogen impact value (N) were calculated and it was tested if there was any difference between the sites.

4. Treatment Technology for VOC Emissions from Oil Refineries : Case study of measures taken to minimize VOC emissions at Swedish petrochemical companies to be appiled at Chineses Refineries
University essay from KTH/Industriell ekologiAbstract : The aim of this thesis is to give suggestions on what measures to take to improve the VOC emission situation in refineries in Tianjin, China, through existing technologies in refineries in Sweden. This has been done by identifying the main places of leakage in oil refineries in Sweden, identifying what VOC compounds are emitted from the plants and the amounts emitted, mapping out different measures taken by oil refineries in Sweden to minimize VOC emissions, evaluating the different measures and suggesting how to move forward with VOC control in Tianjin.

5. Undersökning av avgasemissioner till vatten från dieselinombordsmotorer i fritidsbåtar : En jämförande studie av olika bränslen
University essay from Institutionen för geovetenskaperAbstract : In this Masters Thesis emissions to water from diesel engines in pleasure boats when driven with alternative fuels have been investigated. Two alternative fuels, Fischer-Tropsch-diesel (FT-diesel) and a blend of FT-diesel and rapeseed methyl ester (RME) have been compared with diesel of Swedish environmental class 1 (diesel EC1).
