    Study of plasma - based stack gases cleaning technology to remove SOX and NOX emission from coal-fired power plants in Turkey
    (National Nuclear Center of the Republic of Kazakhstan / Institute of Nuclear Physics, 2003) Turhan, Şeref; Zengin, Tülin; Ocak, Sema; Ünal, Suat; Parlaktürk, Funda; Tuğluoğlu, Nihat; Karadeniz, Serdar; Erçin, Demet; 20000; TAEK-ANAEM
    Environmental problems, which caused by the increased energy demands, have become a serious problem in Turkey. Air and environmental pollutants such as the SOx (SO2, SO3) and NOx (NO, NO2) generated mainly by burning fossil fuels, especially coal with high sulfur contents turn ultimately into sulfuric/sulfurous acid and nitric/nitrous acid in the atmosphere. This acids affect forests, agricultural fields and flora by acidifying the soil and affects fish by acidifying land-borne water. Therefore, Turkey is seeking to install Flue Gas Desulfurization (FGD or deSOx) technology on all newly commissioned coal fired thermal power plants units and to retrofit onto older units to reach introduced emission limits. In this study, both the current energy consumption and production and emission of these gases in Turkey is reviewed and plasma-based stack gas cleaning technologies such as electron beam flue gas treatment (e-beam FGT) and pulsed corona discharge FGT (pulsed CD-FGT) are compared with preferred limestone/gypsum wet-scrubbing (L/G-FGD) technology and evaluated for some coal fired power plants.

    Technical and economical aspects of SO2 and NOx removal from flue gas by electron beam irradiation
    (Turkish Atomic Energy Authority, 2000-10) Turhan, Şeref; Karadeniz, Serdar; Tuğluoğlu, Nihat; Eken, Mahmut; Oktar, Okan; Ercan, İsmail; 20000; TAEK-ANAEM
    The emission of sulfur dioxide (SO2, also SO3) and nitrogen oxides (NO, NO2, called NOx) from fossil fuel burning power and industrial plants is one of the major sources of environmental pollution. These pollutants are named as "acid gases" causing acid rain and also "indirect greenhouse gases" contributing greenhouse effect. Acid rain damages forest, agriculture fields and flora, and cause public health concerns in regions having a number of industrial plants. Today, many countries have started to impose industrial emission limits and this movement has generated renewed interest in finding viable and cost effective solutions to SO2 and NOx pollution control. The conventional technologies, wet scrubbing de-SO2 and de-NOx, now reached their full potential therefore these methods are not expected to provide further improvements in terms of efficiency or reduction in construction costs. However, new technologies are being investigated for industrial scale commercial viability. One of them is electron beam process, which is dry scrubbing process and simultaneously removes SO2 and NOx, and useful by-product for agriculture fertilizer. In this study, the economical and technical aspects of electron beam flue gas treatment process are discussed. Because an electron accelerator facility with electron beam energy of 500 KeV and electron beam current of 20 mA will be installed at ANRTC in TURKEY.
