Opis:: The use of the computer genetic algorithm (GA) for driving a controller device for the industrial flue gas purification systems employing the electron beam irradiation, has been studied. As the mathematical model of the installation the properly trained artificial neural net (ANN) was used. Various cost functions and optimising strategies of the genetic code were tested. These computer simulations proved, that ANN + GA controller can be sufficiently precise and fast to be applied in real installations.

Opis:: Radiation technology may contribute to the environmental protection to a great extent. Electron beam industrial installations for flue gases containing SOx and NOx treatment have been already built in China and Poland. The same technology for high sulphur and high humidity off-gases (low quality lignite) has been successfully tested in an industrial pilot plant in Bulgaria. Pilot plant tests performed in Japan have illustrated that by applying electron beam for municipal waste incinerator off-gases treatment the concentration of dioxins can be reduced by 80%, other persistent organic pollutants can be depredated as well. The positive results of electron beam wastewater treatment are the basis for a full-scale industrial plant being built in the South Korea. A pilot gamma plant for sludge irradiation producing a high grade organic fertilizer is in operation in India. All these achievements are reported in this paper.

Tytuł:: Rate constants of electron-beam PAHs decomposition
Autorzy:: Gerasimov, G.

hydroxyl radical
Opis:: The generalized kinetic model of the electron-beam induced processes in industrial flue gases elaborated earlier is used for the estimation of rate constants of hydroxyl-radicals interaction with high-ringed aromatic compounds. These data are received by means of the fit of the calculated PAHs concentrations to the measured ones as applied to benzo(a)anthracene, benzo(e)pyrene, benzo(a)pyrene, perylene, and dibenzo(a,h)anthracene. It is shown that the concentrations of PAHs decrease by more than an order of magnitude at the absorbed dose D = 20 kGy for compounds with rate constant of their interaction with OH-radical more than 1013 cm3źmol 1źs 1.

Opis:: Operation of marine diesel engines causes signifi cant emission of sulphur and nitrogen oxides. It was noticed worldwide and the regulations concerning harmful emissions were introduced. There were several solutions elaborated; however, emission control for both SOx and NOx requires two distinctive processes realized in separated devices, which is problematic due to limited space on ship board and high overall costs. Therefore, the electron beam flue gas treatment (EBFGT) process was adopted to ensure the abatement of the problem of marine diesel off-gases. This novel solution combines two main processes: fi rst the fl ue gas is irradiated with electron beam where NO and SO2 are oxidized; the second stage is wet scrubbing to remove both pollutants with high efficiency. Laboratory tests showed that this process could be effectively applied to remove SO2 and NOx from diesel engine off-gases. Different compositions of absorbing solution with three different oxidants (NaClO, NaClO2 and NaClO3) were tested. The highest NOx removal efficiency (>96%) was obtained when seawater-NaClO2-NaOH was used as scrubber solution at 10.9 kGy dose. The process was further tested in real maritime conditions at Riga shipyard, Latvia. More than 45% NOx was removed at a 5.5 kGy dose, corresponding to 4800 Nm3 /h off-gases arising from ship emission. The operation of the plant was the first case of examination of the hybrid electron beam technology in real conditions. Taking into account the experiment conditions, good agreement was obtained with laboratory tests. The results obtained in Riga shipyard provided valuable information for the application of this technology for control of large cargo ship emission.

Opis:: Exhaust gases with high SO2 concentrations are emitted from combustion of high sulphur fossil fuels and from different industrial processes (e.g. copper smelter and sintering plants). The application of the electron beam process for SO2 and NOx removal from such flue gases was investigated. A parametric study was carried out to determine the SO2 and NOx removal efficiency as a function of temperature and humidity of irradiated gases, absorbed dose and ammonia stoichiometry. The efficiency 90–95% of SO2 removal was obtained in the optimal treatment conditions with an inlet SO2 concentration of up to 15% vol. The synergistic effect of high SO2 content on NOx removal was indicated. The collected by-product was a mixture of ammonium sulphate and nitrate. The content of heavy metals in the by- -products was many times lower than the values accepted for commercial fertilizers.
