Opis:: Odorization is the process which has crucial impact on the safety of the distribution and usage of natural gas. A very small amounts of odorant are added into naturally odorless fuel. The odorant has distinctive and well odor. Traditionally, used for decades, odorants are based on sulfur compounds. More recently in some countries sulfur-free compound is used as odorant. This article is an attempt to determine the applicability of sulfur-free odorant in natural gas distribution network in Poland. This includes the possibility of implementing a new odorant for the usage in the aspect of existing legislation in the area of odorization. The existing infrastructure used in the process of natural gas odorization has been analyzed and range of necessary adaptation actions has been indicated. The issue of smell diversity in comparison sulfur-free with traditionally used odorants has also been discussed. At the end, the ecological aspects of new odorant usage on a larger scale and re being taken under consideration.

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:: Large seagoing vessels are one of the largest pollution sources in the sea environment world. Marine engines operate with extremely low quality fuels contaminated by sulphur and aromatic compounds. Vessels are responsible for an estimated 14 percent total nitrogen oxide emission and 16 percent sulphur oxide, respectively. Nitrogen oxides emissions cause serious problems including acid rain in local areas such as harbours' vicinity. All diesel engine manufacturers have been working on reducing on NOx from ships. This paper describes one of the experimental methods - using non-thermal plasma reactor. NTP reactor was built as the after-treatment module in exhaust gas system in marine diesel engine. Emission measurements were carried out on the engine with and without demonstrator NTP module. The main aim was to analyze exhaust gas compounds during real engine operation, in accordance with test cycles procedureD-2 and E-2 (ISO-8178 rules). The experiment test bench gives the innovative role in the development exhaust gas after-treatment technology for marine systems. One of the most promising methods to decrease the number of toxic compounds from exhaust gas is implementing of NTP reactor as after main treatment module. As the next steps a two-stage plasma-chemical process for the control of harmful compounds: non-thermal plasma reactor and catalyst is proposed. This combination should be more effective and probably gives reduction with more efficiency of harmful exhaust gas compounds.

Opis:: The control of nox emissions from marine engines proves a challenge. Diesel engine manufacturers have been investigating a variety of methods with aim of reducing nox emissions. Currently, the plasma technology is undergoing rapid development in application to diesel engine exhausts. A combination of non-thermal plasma with catalysts can be referred to plasma assisted catalysts technology. This paper briefly describes research efforts aimed at non-thermal plasma reactor development for ship use with primary focus on NO oxidation condition. The part scale plasma reactor models have been designed and manufactured for the purpose of this trial. Exhaust emission plasma after-treatment module was fitted on exhaust outlet path of the marine test bed engine for fractional exhaust gas stream examination. Subsequently, the comprehensive series of trials were performed to assess the exhaust flow properties of the main exhaust channel and plasma reactor by-pass duct. Emission measurements were carried out on engine at steady-state operation. The NO reaction activity was a major task of the experiment and throughout the measurements, the engine outlet nox levels (NO and NO2) were monitored with simultaneous NO, NO2, N2O level recording after NTP reactor.

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:: The article describes the technology of NO_x emission abatement by SNCR method. The scope of research included CDF simulations as well as design and construction of the pilot plant and tests of NO_x reduction by urea in the plant located in industrial pulverized-coal fired boiler. The key step of research was to determine the appropriate temperature window for the SNCR process. The proposed solution of the location of injection lances in the combustion chamber enabled to achieve over a 30% reduction of NO_x . It is possible to achieve higher effectiveness of the proposed SNCR technology and meet the required emission standards via providing prior reduction of NO_x to the level of 350 mg/um³ using the primary methods.
