Opis:: Two heat pump systems with the highest energy performance indicators were chosen for an analysis. Those most efficient systems for heating and cooling are ground source heat pumps (GSHP) and the exhaust air heat pumps (EAHP). Consequently, two cases (case A and case B) with different pump configurations were related to a reference case R represented by gas-fired boilers covering heating needs and compression refrigeration units ensuring cooling needs. Technical assessment in the form of coefficients of performance as well as primary energy ratings were completed. An environmental impact taking into account CO2, SO2 and NOx emissions of analysed heat pump systems was also evaluated.

Opis:: The objective of the present study was to experimentally investigate environmental emissions and performance of a stationary type diesel engine fuelled with biodiesels derived from two different feedstocks; one is more unsaturated (rice bran biodiesel) and the other one is more saturated in nature (palm biodiesel) and compare with petrodiesel. Tests were conducted in a single cylinder, air cooled, direct injection diesel engine. From the experimental results, it was found that the nitrogen oxides emissions were higher with biodiesel fuels. The hydrocarbon and carbon monoxide emissions of palm biodiesel were lower than the other test fuels. The smoke emission of rice bran biodiesel was the lowest compared to the rest of the fuels. A considerable reduction in thermal efficiency was found with both the biodiesels when compared to diesel. From the present study, it is concluded that the biodiesels derived from palm and rice bran oils with their different fatty acid composition, show lower exhaust emissions and closer performance characteristics to diesel.

Opis:: A nitric acid plant in Devnya, Bulgaria has implemented a project for catalytic decomposition of nitrous oxide which resulted in reducing N2O emissions from the plant and the overall N2O emissions from the industrial sector in Bulgaria. After implementing the catalyst in September 2005 till the end of 2011, a total amount of 3133 Mg N2O emissions has been measured while the supposed value of N2O emissions without the catalyst being installed would have been 9747 Mg which means a total reduction of 6614 Mg. The results from the research prove the emission reduction potential of the catalyst.
