12th International Conference on High-Power Particle Beams. BEAMS'98. Proceedings (Cat. No.98EX103), 1998
Many organic synthesis processes are accompanied by ventilation emissions of exhaust air contaminated with the vapor of volatile organic compounds (VOCs). Recent investigations have shown the efficiency of using electron beams to remove the vapor of VOCs from exhaust air. The use of pulsed electron beams for these purposes has not been, adequately explored yet. The goal of the present ...

Many organic synthesis processes are accompanied by ventilation emissions of exhaust air contaminated with the vapor of volatile organic compounds (VOCs). Recent investigations have shown the efficiency of using electron beams to remove the vapor of VOCs from exhaust air. The use of pulsed electron beams for these purposes has not been, adequately explored yet. The goal of the present work was to study the processes of removal of VOCs from the air by means of a 3-ns electron beam. Subjects of inquiry included acrolein, styrene and benzene, i.e., the most common toxic VOCs present in emissions by various enterprises, synthesizing organic compounds, producing plastic materials, etc.
In these paper we have used a metal oxide sensor based electronic nose (EN) to analyse five tea samples with different qualities, namely, drier month, drier month again over fired, well fermented normal fired in oven, well fermented over fired in oven, and under fermented normal fired in oven. The flavour of team is determined mainly by its taste and smell, which generated by hundreds of volatile organic compounds (VOCs) and non-volatile organic compounds present in tea. These VOCs are present in different ratios and determine the quality of the tea. For example Assamica (Sri Lanka and Assam tea) and Assamica Sinesis (Dajeeling and Japanese tea) are two different species of tea giving different flavour notes. Tea flavour is traditionally measured through the use of a combination of conventional analytical instrumentation and human organoleptic profiling panels. These methods are expensive in terms of time and labour and also inaccurate because of lack of either sensitivity or quantitative information. In this paper an investigation has been made to determine the flavours of different tea samples using an EN and to explore the possibility of replacing existing analytical and profiling panel methods. The technique uses as array of 4 metal oxide sensors (MOS), each of, which has an electrical resistance that has partial sensitivity to the headspace of tea. The signals from the sensor array are then conditioned by suitable interface circuitry. The data were processed using principal component analysis (PCA), fuzzy C means algorithm (FCM). We also explored the use of self-organizing map (SOM) method along with a radial basis function network (RBF) and a probabilistic neural network (PNN) classifier. Using FCM and SOM feature extraction techniques along with RBF neural network we achieved 100% correct classification for the five different tea samples with different qualities. These results prove that our EN is capable of discriminating between the flavours of teas manufactured under different processing conditions, viz. over-fermented, over-fired, under fermented etc.
Using air sampling canisters and pre-concentrator and gas chromatograph-mass spectrum instrument, this paper studied the characterization profiles of 52 volatiie organic compounds (VOCs) emitted from 13 kinds of typical anthropogenic sources and their content in the ambient air of pearl river delta (PRD), South China. Then chemical mass balance model was run to calculate their source apportionment in the atmosphere of PRD. The results showed that there didn't exist the profile with single molecular mark at all in PRD, but the complex multi-linearity emission sources could be identified by the VOCs characteristic profiles with consideration on the uncertainty of atmospheric chemical reactions, pollutants diffusion and deposition and sources loss, etc. The sources apportionment of VOCs in PRD were mobile sources 15.0%, stationary industries 29.4%, area sources 25.7% and unidentified sources 29.9% . In 2002, stationary sources and mobile sources were the most important to be controlled by government, however, area sources was troublesome.
The superimposed barrier discharge and activated carbon filter hybrid systems are used to remove toluene and trichloro-ethylene (TCE) from air streams. The superimposed barrier discharge consists of silent and surface discharges. Experiments are conducted for the gas flow rate from 1 to 10 L/min., applied power from 0 to 7 W and toluene and TCE initial concentration from 0 to 2,000 ppm for 60 Hz AC applied voltage conditions. Discharge byproducts are measured by FTIR, GC and TLV VOC detector. The results shows that: (1) toluene decomposition rate monotonically increases with increasing applied power; (2) approximately 90% of toluene is removed by plasma reactors alone and up to 98% is removed by hybrid systems; (3) TCE removal rate by hybrid system is 90% and up to 50% is removed by a discharge reactor alone; (4) the pressure drop of the reactor and carbon filter increase with increasing gas flow rate; (5) TCE decomposition to form CO/sub 2/, H/sub 2/O and Cl/sub 2/ and except CO/sub 2/ and H/sub 2/O these discharge byproducts are absorbed in activated carbon filters; (6) no COCl/sub 2/, HCl, CO, NO/sub x/ and O/sub 3/ are observed in a discharge byproducts for the present range of experiments; and (7) the energy yield for toluene decompositions is up to 30 g/kWh, and up to 15 g/kWh for TCE decompositions.
Volatile organic compounds (VOCs) emitted from larch particleboard at different temperatures were studied in this paper. The small climate chamber and portable VOC gas monitor were used to measure VOCs quantities. Particleboard 1 (with hot-pressing time 3.5 min and hot-pressing pressure 35 MPa) and particleboard 2 (with hot-pressing time 2.7 min and hot-pressing pressure 30 MPa) were respectively examined at climate temperatures of 15, 23, 25, and 35°C. At a temperature of 23°C, particleboard 1 showed a higher initial emission than particleboard 2. VOC emissions from particleboards at 35°C were higher than ones at other temperatures. The emission study shows that hot-pressing parameters of particleboard and climate temperature have obvious effect on VOC emission. With the extension of hot-pressing time and the increase of hot-pressing pressure, VOC emissions increase. The increase of temperature can accelerate VOC emissions. On the other hand, temperature markedly affects the short-term emissions and it has less impact on the long- term emissions.
Biofilter technology is a cost-effective technique with an excellent efficiency for volatile organic compound (VOC) treatment. It is an attractive alternative to conventional air pollution abatement technologies. In this project, a combination of a Biosrubber and a Biofilter (called Biofilter System) was tested with VOC-laden exhaust air from a semiconductor fab. This Biofilter System meets all requirements of German and European law and protects the environment. The results of this project demonstrate that it is possible to establish this innovative and emerging technology in the semiconductor industry.
