We developed a new emission inventory for Asia (Regional Emission inventory in ASia (REAS) Version 1.1) for the period 1980–2020. REAS is the first inventory to integrate historical, present, and future emissions in Asia on the basis of a consistent methodology. We present here emissions in 2000, historical emissions for 1980–2003, 5 and projected emissions for 2010 and 2020 of SO 2 , NOx, CO, ...

Ambient aerosol during a heavily polluted episode in wintertime was characterized using real-time single particle aerosol mass spectrometry (SPAMS) in urban Nanning, a capital city in the Southwestern China. More than two million individual particles analyzed by SPAMS were classified into 8 major clusters based on the mass spectral patterns. A group of vanadium-rich particles were identified as...

This work presents a simulation approach to the design and economic evaluation of fuel oil hydrotreating processes for the control of SO2 and NOx emission in an Iranian steam power plant. The percent of fuel oil desulphurization was estimated from the SO2 emissions standards for power plants. Based on two different scenarios according to (I) European and (II) Iranian standards, the design and s...

this study was focused on measuring air pollutants emission from factories producing the asphalt related products in delijan industrial estate, which is the main center of asphalt related products in iran. emissions of four factories were analyzed for air pollutants using a stack analyzer, testo 360, testo co., and germany. the average concentration of all measured stacks for pm, thc, co, nox, ...

Industrial medicine and hygiene have made considerable strides in this country during the past two decades. A great many facts dealing with the signs, symptoms, toxicology, and preventive aspects of this branch of the medical sciences have been accumulated, but, unfortunately, the application of the data and the distribution of industrial medical care have not proceeded with parallel speed. In ...

This paper describes an estimation method for gas turbine compressor degradation and an economical optimisation model for determining the optimal compressor washing cycles. The optimisation model aims at minimising fuel consumption and emissions in combined-cycle power plants. The results presented are of significant importance for power plants operators that have the possibility of frequently ...

abstract the goal of this research is simulating an optimum reactor to eliminate greenhouse gases, mainly co2, through combined cycle in stacks of power plant, using a strong base (sodium hydroxide) thinned by water. during this process sodium bicarbonate salt is generated together with water and the produced salty water is desalinated and its useful salts are also extracted. four scenarios hav...
