AB  - The removal of volatile organic compounds (VOCs) from numerous emission sources is of crucial importance due to more rigorous demands on air quality. Different technologies can be used to treat the VOCs from effluent gases: absorption, physical adsorption, open flame combustion, thermal and catalytic incineration. Their appropriateness for the specific process depends on several factors such as efficiency, energy consumption, secondary pollution, capital investments etc. The distinctive features of the catalytic combustion are high efficiency and selectivity toward be­nign products, low energy consumption and absence of secondary polluti­on. The supported noble catalysts are widely used for catalytic incineration due to their low ignition temperatures and high thermal and chemical stability. In our combined system adsorption and desorption are applied in the spouted bed with draft tube (SBDT) unit. The annular zone, loaded with sorbent, was divided in adsorption and desorption section. Draft tube enabled sorbent recirculation between sections. Combustion of desorbed gases to CO2 and water vapor are realized in additive catalytic reactor. This integrated device provided low concentrations VOCs removal with reduced energy consumption. Experiments were conducted on a pilot unit of 220 m3/h nominal capacity. The sorbent was activated carbon, type K81/B - Trayal Corporation, Krusevac. A sphere shaped commercial Pt/Al2O3 catalyst with "egg-shell" macro-distribution was used for the investigation of xylene deep oxidation. Within this paper the investigations of removal of xylene vapors, a typical pollutant in production of liquid pesticides, in combined adsorber/desorber/catalytic reactor system is presented.
AB  - U okviru ovog rada izvršena su ispitivanja adsorpcije ksilola, kao Predstavnika volatilnih organskih jedinjenja, na aktivnom uglju. Ispitivanja su vršena u cilju dobijanja parametara za određivanje efikasnosti adsorpcije realne smeše polutanata. Takođe, ispitivana je desorpcija ksilola u širokom temperaturnom intervalu u cilju određivanja optimalne temperature desorpcije i efikasnost katalitičkog sagorevanja desorbovanog ksilola na katalizatoru. Ova ispitivanja bila su osnov za razvoj integrisanog sistema adsorber-desorber-katalitički reaktor za uklanjanje malih koncentracija ksilola. Ispitivanja su obuhvatila tretiranje gasne smeše vazduh-ksilol, koja je po svom sastavu slična otpadnim gasovima iz pogona za proizvodnju tečnih pesticida. Eksperimenti su izvršeni na pilot postrojenju nominalnog kapaciteta 220 m3/h smeše vazduha sa ksilolom. U ispitivanjima je korišćen komercijalni adsorbens aktivni ugalj i katalizator sa kontrolisano dispergovanom platinom na spoljnoj površini sfere poroznog AI2O3 nosača.

AB  - The widely used herbicide, dimethylamine salt of 2,4-dichlorophenoxy acetic acid (2,4-D-DMA), is usually prepared by mixing a dimethylamine (DMA) aqueous solution with a solid 2,4-dichlorophenoxy acetic acid (2,4-D). The vapors of the both, reactants and products, are potentially hazardous for the environment. The contribution of DMA vapors in overall pollution from this process is most significant, concerning vapor pressures data of these pollutants. Therefore, the control of the air pollution in the manufacture and handling of methylamines is very important. Within this paper, the optimal air pollution control system in preparation of 2,4-D-DMA was developed for the pesticides manufacturing industry. This study employed the simple pollution prevention concept to reduce the emission of DMA vapors at the source. The investigations were performed on the pilot plant scale. To reduce the emission of DMA vapors, the effluent gases from the herbicide preparation zone were passed through the packed bed scrubber (water scrubbing medium), and the catalytic reactor in sequence. The end result is a substantially improved air quality in the working area, as well as in the urbanized areas located near the chemical plant.
