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...

engine performance depends on two main factors of engine speed and ignition time. ignition timing can affect engine life, fuel economy and engine power. in this paper, to study engine performance of peugeot 206 tu3a with comparison ratio of 10.5:1 and displacement of 1361cc in matlab software, a two-zone burned/unburned model with the fuel burning rate described by awiebe function was used for ...

processing of minerals and production of metals has increased greatly in recent years. as a result, the quantities of waste material and pollutants have also increased. in many cases technology has changed to cope with the problem. processes have been either modified to decrease emissions, or replaced by others that are less polluting even if at a higher cost. this paper briefly reviews example...

Background: Iran is located in the seventh rank in terms of CO2 emissions resulting from the fuel combustion in the world. Gas compressor booster stations, due to the several sources of contaminants, are causing the release of large amounts of CO2 and CH4, which will cause climate change therefore, estimating the emissions of the gases from oil and gas, different processing units are necessary....

introduction earth's atmosphere plays an important role in preventing the temperature decrease. one of the principal factors of environmental pollution and the main source of earth's climate and biodiversity changes is greenhouse gas emissions from various sources, particularly agricultural sector. agriculture sector is considered as a major source of greenhouse gas sequestration, including me...

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...

population growth and increasing industrial and agricultural activities that cause ghg emissions and risk from environmental management is a serious challenge. in this research, the ghg emissions from peanut production as a potential feedstock for biodiesel fuel was investigated. data were collected through interviews with 75 peanut farmers. the cultivated areas were divided into three categori...

the demand for fossil fuel in the transport sector is constantly increasing and transportation is ranked amongst the highest greenhouse emitting sectors globally. today, tackling co2 emissions from road transport a widely discussed topic and constitutes a milestone towards reaching a sustainable, carbon neutral economy. this challenge is being described in various initiatives adopted in the eur...
