Umubare munini wimyuka ya asfalt yatatanye hamwe na 5-7mg / m ~ 3 ikorwa mugihe cyo gutunganya umusaruro wa karubone y'uruganda rwa alumina.Niba isohotse mu buryo butaziguye, bizagira ingaruka zikomeye ku bidukikije ndetse n'abakozi bo mu ruganda.Intego kuri iki cyuka cyumubyimba, uduce duto twabazwe kokiya ikoreshwa mukuyungurura no kuyisukura, kandi kokiya yuzuye ibarwa isubirwamo muburyo bushya bwo kuvugurura ubushyuhe.

Ubwa mbere, hasuzumwe uburyo bwa adsorption ya kokiya yabazwe, kandi hasesenguwe ingaruka zubushyuhe bwa adsorption, ubunini bwa fume yibibanza, umuvuduko wumwanya hamwe nubunini bwa kokiya yabazwe ku ngaruka za adsorption ya kokiya yabazwe.Ibisubizo byubushakashatsi byerekana ko ubwinshi bwimyuka ya pompe yamamajwe na kokiya ibarwa yiyongera hamwe no kwiyongera kwa inlet yibanze ya fume.Umuvuduko muke muto, ubushyuhe buke, nubunini buto byose bifite akamaro kuri adsorption ya fume ya pisine na kokiya yabazwe.Hakozwe ubushakashatsi bwa adsorption thermodynamic ya kokiya yabazwe, yerekanaga ko inzira ya adsorption yari adsorption yumubiri.Gusubira inyuma kwa adsorption isotherm yerekana ko inzira ya adsorption ihuye na Langmuir.

Icya kabiri, gushyushya ibyuka no gukira kwa kokiya yuzuye.Hakozwe iperereza ku ngaruka ziterwa na gazi itwara, ubushyuhe bwo gushyushya, ingano ya kokiya yuzuye hamwe nigihe cyo kuvugurura uburyo bwiza bwo kuvugurura kokiya yabazwe.Ibisubizo byubushakashatsi byerekana ko iyo umuvuduko wogutwara gaze yikwirakwiza, ubushyuhe bwo gushyuha bwiyongera, hamwe na kokiya nyuma yo kubara kwuzuye kugabanuka, bigira akamaro mukuzamura imikorere mishya.Shyira hamwe kandi ushireho gaze umurizo wa gazi, kandi igipimo cyo gukira kiri hejuru ya 97%, ibyo bikaba byerekana ko uburyo bwo kwegeranya no kwinjiza bushobora kugarura bitum mumyuka ya gazi umurizo.

Hanyuma, sisitemu eshatu zo gukusanya gazi, kweza no kuvugurura zateguwe, kandi ibisubizo byubushakashatsi bishyirwa mubikorwa.Ibisubizo byo gukoresha inganda byerekana ko uburyo bwo kweza umwotsi wa asifalt na benzo (a) pyrene bigera kuri 85.2% na 88.64%, mugihe isuku ikoreshwa mugufata no kweza imyotsi ya asfalt itatanye kandi idashyizwe hamwe.Ubwinshi bwumwotsi wa asfalt na benzo (a) pyrene kumusozo wogusukura byari 1.4mg / m ~ 3 na 0.0188μg / m ~ 3, naho imyuka yanduye yari 0.04kg / h na 0.57 × 10 ~ (-6) kg / h.Yageze ku rwego rwa kabiri rwo gusohora byimazeyo imyuka ihumanya ikirere GB16297-1996.
