this work presents a simulation approach to the design and economic evaluation of fuel oil hydrotreating processes for control of so2 and nox emission in an iranian steam power plant. minimum amount of required fuel oil desulphurization was calculated from the limit of so2 emissions of power plants in two different scenarios based on (i) european and (ii) iranian so2 emission standards. based o...

nitrous oxide (n2o) has significant impact on global warming and leads to the depletion of ozone in the stratosphere. agricultural soil is regarded as a major source of n2o emissions. in recent years, greenhouse grown vegetables have rapidly developed in china. although excessive fertilizer application in greenhouse vegetable production can result in increased n2o emissions, research data on su...

Background: Combustion of fossil fuels contributes to sulfur dioxide (SO2) emissions. To deal with this issue, the government of Iran has appointed the oil refineries to upgrade their installations and produce high quality fuels. Thus, this study investigated the status of SO2 emissions in Iran and the capability of advanced technologies to control SO2 emissions. Methods: The status of SO2 em...
