The paper presents initial research of effects of some factors on the amount of gaseous pollutants formation during medical waste incineration in a two-stage starved air fluidised bed reactor. In the research was included the impact of such factors as oxygen contents in flue gases, frequency of waste loading, momentary mass flow of waste and temperature in the secondary combustion chambers. Measurements showed that the waste incineration in large amount periodically caused excessive emissions incomplete combustion products (CO, HC), especially during wrong operation of the combustion system. The work demonstrated that the essential importance for CO and HC formation reducing …
Anaerobic Catalytic Oxidation Of Hydrocarbons In Moving Heat Waves. Case Simulation: Propane Oxidative Dehydrogenation In A Packed Adiabatic V-Ti Oxide Catalyst Bed, Andrey N. Zagoruiko
Anaerobic Catalytic Oxidation Of Hydrocarbons In Moving Heat Waves. Case Simulation: Propane Oxidative Dehydrogenation In A Packed Adiabatic V-Ti Oxide Catalyst Bed, Andrey N. Zagoruiko

The model simulation study has shown that the anaerobic process of oxidative dehydrogenation of propane under periodic alteration of feeding between propane and air may be realized in adiabatic catalyst beds in stable continuous cyclic mode in two-reactor scheme. In case of appropriate choice of process parameters (cycle duration, feeding flow rates) the process appears to be autothermal, i.e. it does not require any inlet gas preheating for stable operation. Compared to similar steady-state adiabatic process, the proposed process is characterized with much lower maximum catalyst temperatures, giving the way to process pure propane without diluting it with inert gases, …

Real-Time Measurement Of The Size Of Air Particulates, Marek Bogacki, Robert Oleniacz, Marian Mazur, Stanisław Kamiński
Real-Time Measurement Of The Size Of Air Particulates, Marek Bogacki, Robert Oleniacz, Marian Mazur, Stanisław Kamiński

The gravimetric method of measuring PM10 particulate concentration in air is the reference method used in Poland and in the European Union. To get information on mass fractions of lower diameter particulates (e.g. PM5, PM2,5 or PM1) one usually has to apply various pre-sorters (most often of the impact type). This paper presents a new device that measures air particulate sizes in real time. The device makes it possible to classify (sort) air particulates according to size into 256 granularity classes from about 0.4 µm up to 300 µm. Tests of a device prototype were conducted in Warsaw at the …

The measurement results of quantity of dust pollutants originated and emitted to air from LWG (Castner) furnaces during graphitisation process of coal electrodes were presented in the paper. The investigation was carried out for total dust, total tar substances and polycyclic aromatic hydrocarbons (PAHs). The measurements were performed both before and after the flue gas control system (catalytic burning and wet cleaning). Thus changes of the substance concentrations in the gases for the cleaning system were estimated. As a result of the investigation was conclusion that the graphite process of coal electrodes in LWG stoves is not a significant source …

Research results of the air pollutant emissions from the graphitisation process of fine products in the Acheson electric resistance furnace (discharge capacity 5,5 Mg) were presented in the paper. Research was performed for two kinds of raw material inputs (based on petroleum coke and pitch coke). Approximately 40-hours measurement series were carried out for each material including mainly such substances like carbon monoxide, hydrocarbons, nitrogen oxides, sulphur dioxide, hydrogen sulphide, carbon disulphide, ammonia, benzene, toluene, xylenes, total dust, tar substances and polycyclic aromatic hydrocarbons. Both average and maximum concentrations and mass streams in the flue gases and average emission factors …

Removal Of Methyl-Tert Butyl Ether From Water By A Pulsed Arc Electrohydraulic Discharge System, Danielle M. Angeloni, Sarah E. Dickson, Monica B. Emelko, J -S Chang

The removal of methyl-tert-butyl ether (MTBE) from water by a pulsed arc electrohydraulic discharge (PAED) system was investigated experimentally at the laboratory scale. The effects of arc electrode gap, detention time and initial solution pH on the efficacy of MTBE treatment by PAED were investigated. A 0.3 kJ/pulse spark-gap-type power supply was employed in combination with a 3.0 L flow-through reactor. Experimental results showed that: 1) oxidation reactions are induced by this PAED system; 2) removal efficiency increases with increasing cumulative input energy (kW·h/m3 or kJ/L); 3) removal efficiency decreases with increasing arc electrode gap; and 4) initial solution pH …

Pulsed Electrohydraulic Discharge Characteristics In An Eccentric Electrode Cylindrical Reactor With Pbs, A Yamataki, D M. Angeloni, Sarah E. Dickson, Monica B. Emelko, K Yasuoka, J -S Chang

Pulsed arc electrohydroulic discharge (PAED) has been proposed as a water treatment technology for the removal of chemical and microbial contaminants. In this work, we examined the fundamental characteristics of a PAED system with an eccentric electrode cylindrical reactor. Phosphate-buffered saline (PBS) water was used in lieu of tap water, because the conductivity of PBS is much higher than that of tap water. The results show that the voltage and current waveforms generated in PBS and tap water are very different due to the higher conductivity of PBS. Strong pressure waves and UV emission were also observed in PBS.
Decision Support System For Rural Water Supply In The Nilgris District Of South India, Daniel Olsen, Sarah E. Dickson, Brian Baetz
Decision Support System For Rural Water Supply In The Nilgris District Of South India, Daniel Olsen, Sarah E. Dickson, Brian Baetz

A considerable amount of knowledge exists for planning, designing, and implementing rural water supply schemes in developing countries around the world. Generalized decision support systems (DSSs) are used to tackle the daunting task of providing water in areas that have poor water resources and limited financial capacity. However, there is a lack of site-specific DSSs that utilise local hydrological and socio-economic data for assessing regionally-based rural water supply schemes. In the Nilgiris District of South India, an organizational structure exists for improving local water resources through watershed management projects, but many of the tools used to make informed decisions are …
