The work presents selected results of atmospheric dispersion modeling and air quality impact assessment for pollutant emissions from installations of ArcelorMittal Poland S.A. Unit in Krakow (Poland). The assessment was carried out for the most unfavourable emission variant probable to take place in the period 2007-2016. In the calculations were taken into consideration typical for steelworks particle matter pollutants (total dust, heavy metals, tar substances and PAHs including benzo-a-piren) and gaseous substances (SO2, NO2, CO, HC, HCl, HF, NH3, HCN, H2S, CS2, H2SO4, BTX, phenol and pyridine). As the result of estimations, carried out according to the Polish reference method …

The work presents emission factors of main air pollutants for installations of ArcelorMittal Poland S.A. Unit in Krakow (Poland) in comparison with analogous characteristic emissions for iron and steel industry in West Europe. In the comparison four installations (to coke, sinter, pig iron and steel production) were taken into consideration. The emission rates from ArcelorMittal Poland S.A. Unit in Krakow were estimated on the basis of the emission levels and production data from 2004, when took place the most significant production of liquid steel during last several years. As a result of the analysis, most the emission factors (with the …

The paper characterises the method of preparing the HCC and Rubba-type materials used to manufacture small carbon and graphite products, and the composition of waste gases escaping from the mixers for these materials. For the process of mixing the two materials under examination, two measurement series were completed, mainly covering the period from when the binder was added to the properly pre-heated dry mass until the mixer discharged. The results shown apply only to those substances which occur just in the gaseous phase, that is CO, CO2, O2, H2, aliphatic hydrocarbons (C1-C6) and BTX (benzene, toluene, ethylbenzene and xylene) as …

The paper presents the results of measurements of concentrations of dust substances in flue gases from the mixing process of two type od raw materials (HCC and Rubba) used in the manufacture of fine carbon and graphite products. These raw materials differed in the method of preparation including the heating temperature in various stages of mixing and duration of the process. Due to the use in the mixing process liquid binders, significant amounts of tar substances in liquid and solid phase were discharged from the mixers. In the analyzed flue gases was determined total dust content of tar substances, polycyclic …

The research object was a medical waste incineration plant with a capacity of 150 kg per hour equipped with a flue gas treatment system based on dry sorption process using a lime-carbon reagent with adsorbent removing in high-efficiency particulate collector. As the dry sorption agent was used a mixture of high reactive hydrated lime and activated carbon injected to combustion gases by pneumatic feeder. Activated carbon content in the mixture was 5-10 % by mass. Applied collector was ceramic filter with total filtration area of 120 m2 and guaranteed outlet dust concentration under 5 mg/Nm3. Among others things the aims …

Pulsed arc electrohydraulic discharge (PAED) offers concurrent treatment of chemical and microbial target compounds in water by several mechanisms. Here, Escherichia coli, Bacillus subtilis spore, and MS2 bacteriophage inactivation by PAED were investigated using two bench-scale reactors (0.7 and 3 L). A plasma channel was created between a pair of iron electrodes set 0.5 mm apart in these reactors. Pulsed applied voltage was supplied at approximately 0.3 kJ/pulse (~100 ìsec). In the 0.7-L reactor, median E. coli, B. subtilis, and MS2 reductions of 2.4-, 4.6-, and 3.7-log, respectively, were observed after approximately 80 seconds of treatment in water with a …

Expansion Of The Discontinuous Gas Phase And Its Effect On Mass Flux From A Non-Aqueous Phase Liquid (Napl) Pool, Kevin G. Mumford, James E. Smith, Sarah E. Dickson
Sarah E Dickson
The partitioning of non-aqueous phase liquid (NAPL) compounds to a discontinuous gas phase results in the repeated spontaneous expansion, snap-off, and vertical mobilization of the gas phase. This mechanism has the potential to significantly affect the mass transfer processes that control the dissolution of NAPL pools by increasing the vertical transport of NAPL mass and increasing the total mass transfer rate from the surface of the pool. The extent to which this mechanism affects mass transfer from a NAPL pool depends on the rate of expansion and the mass of NAPL compound in the gas phase. This study used well-controlled …
On The Appropriate “Equivalent Aperture” For The Description Of Solute Transport In Single Fractures: Laboratory-Scale Experiments, Qinghuai Zheng, Sarah E. Dickson, Yiping Guo
On The Appropriate “Equivalent Aperture” For The Description Of Solute Transport In Single Fractures: Laboratory-Scale Experiments, Qinghuai Zheng, Sarah E. Dickson, Yiping Guo
Sarah E Dickson
Three distinct definitions of ‘‘equivalent aperture’’ have been used in the literature to describe variable-aperture fractures; however, significant inconsistencies exist in the literature as to which ‘‘equivalent aperture’’ is appropriate for simulating solute transport. In this work, a systematic series of hydraulic and tracer tests was conducted on three laboratory-scale fracture replicas, and the cubic law, mass balance, and frictional loss apertures were calculated. The analytical solution of the one-dimensional advectiondispersion equation was fit to the experimental breakthrough curves. Additionally, one of the experimental aperture fields was measured directly using a light transmission technique. The results clearly demonstrate that the …

Slow Gas Expansion In Saturated Natural Porous Media By Gas Injection And Partitioning With Non-Aqueous Phase Liquids, Kevin G. Mumford, Sarah E. Dickson, James E. Smith
Sarah E Dickson
The partitioning of volatile non-aqueous phase liquid (NAPL) compounds to a discontinuous gas phase can result in the expansion of that gas phase, and the resulting gas flow can significantly affect the mass transfer from NAPL source zones. This recently reported gas flow generated by the spontaneous expansion of a discontinuous gas phase has not been extensively characterized in the literature. This study measured the expansion rate of a single gas cluster in a 1.1 mm sand above a pool of trans-1,2-dichloroethene (tDCE) in small-scale flow cell experiments. To characterize the gas flow, gas injection experiments in three sizes of …
