… be used to produce biogas. Upgrading biogas represents an increase in methane concentration from about 65 % to about 97 %. In addition, particles and contaminants must be sepa-rated from the upgraded biogas. There are various methods for upgrading and this report compares six …
Samband mellan miljöförbättrande arbete i pappers- och massaindustrin och föroreningar i närområdet
Examensarbete, avancerad nivå · Uppsala universitet
En nedgång har setts i Sverige och Europa när det gäller luftföroreningar de senast årtiondena. Nedgången beror bland annat på minskade emissioner från industrier, övergång från uppvärmning med olje- och kolpannor till fjärrvärme och förbättrad bränslekvalitet. Denna studie …
