Abstract

The BAT concept is defined as well as its implementation in the cement industry. Processes for reducing the emission of hazardous gases in the cement industry, which are also utilized as part of the BAT implementation in other industries, are extensively described. The comparison between selective non-catalytic reduction (SNCR) and selective catalytic reduction (SCR) as secondary processes for lowering NOx emissions is characterized. Flame cooling, low NOx burners and staged combustion as the primary NOx reduction techniques are covered. It is presented how the activated carbon addition and implementation of wet scrubber reduces SOx emissions. Fabric filters, electrostatic precipitators (ESPs), or a mix of both, known as hybrid filters, are analyzed technologies for reducing dust emissions The approaches of reducing energy consumption, demands for usage of alternative fules and optimizing working conditions, as an example of its overall contribution to greater cement production effectiveness and minimizing adverse effects on the environment are highlighted.

Abstract (croatian)

Definiran je BAT koncept i njegova primjena u industriji cementa. Opširno su opisani procesi za smanjenje emisije štetnih plinova u industriji cementa, koji se također koriste u sklopu implementacije BAT-a u drugim industrijama. Opisana je usporedba između selektivne nekatalitičke redukcije (SNCR) i selektivne katalitičke redukcije (SCR) kao sekundarnih procesa za smanjenje NOx emisija. Hlađenje plamena, plamenik s niskim sadržajem NOx i stupnjevito sagorijevanje kao primarne redukcijske tehnike su obuhvaćeni. Predstavljeno je kako dodavanje aktivnog ugljena i primjena mokrog skrubera smanjuje SOx emisije. Filteri od tkanine, elektrostatski precipitatori (ESP) ili njihova mješavina, poznati kao hibridni filteri, analizirane su tehnologije za smanjenje emisije prašine. Pristupi smanjenju potrošnje energije, zahtjevi za korištenjem alternativnih goriva i optimizacija radnih uvjeta, kao primjer ukupnog doprinosa većoj učinkovitosti proizvodnje cementa i smanjenju štetnih učinaka na okoliš su istaknuti.
