Abstract: A method for removal of SOx and NOx from an exhaust gas that contains SOx, NOx, soot and water vapor, the exhaust gas originating from a combustion of a fuel where the combustion takes place in an internal combustion engine. The exhaust gas is passed through at least one catalytic reactor having an oxidation catalyst, in which catalytic reactor at least SO2 is converted to SO3 and NO is converted to NO2. Thereafter the exhaust gas is passed through a condenser and cooled to a temperature which is below the dew point temperature of the water in the condenser such that SO3, NO2 and water is condensed and SO3 and NO2 is dissolved into the condensed water and removed from the exhaust gas.

Abstract: The present invention relates to a method for production of photovoltaic wafers and abrasive slurries for multi-wire sawing of wafers for photovoltaic applications, and more specific to abrasive slurries which are easy to remove from the wafers after sawing, where the abrasive slurry comprises one part recycled abrasive slurry, an alkali in sufficient amount to provide a pH in the abrasive slurry mixture in the range from 6.0 to 9.0, and one part novel abrasive slurry in an amount sufficient to provide an ion content in the abrasive slurry mixture to provide an electric conductivity of less than 50 ?S/cm.
