Othandizira yoyeretsa mpweya woipawu

Kuchuluka mpweya ndi zolemekezeka, choncho kukonza malasha mpweya likupitirirabe kwambiri panopa chaka chilichonse. Gwero yaikulu ya mpweya zoipa mu mlengalenga ndi mafakitale mphamvu ndi zoyendera msewu.

mpweya kuyeretsedwa mpweya anachita m'njira zosiyanasiyana, Pakati zothandiza kwambiri nthawi zambiri ndi njira othandizira kwa deactivation ndi kuchepetsa ambiri zoipitsa msinkhu pazipita chovomerezeka. Othandizira kuyeretsa adalipo ndi zifukwa zachuma.

Childs, njira othandizira aliyense ali ndi angagwiritsidwe ntchito kwambiri kuyeretsa mpweya zosiyanasiyana ndondomeko. Njira imeneyi n'zotheka kuyeretsa mpweya mafakitale ku oxides asafe , ndi sulfure, carbon monoxide zoipa mankhwala organic ndi zina Mankhwala oipitsa poizoni. M'menemo Mankhwala oipitsa mtima mu zochepa zoipa ndi wowona, ndipo nthawi zina ngakhale zothandiza. The njira yomweyo ikuchitika kuyeretsedwa mpweya utsi. Kwenikweni, njira tichipeza atsatire njira za mogwirizana mankhwala mankhwala pamaso pa catalysts, chifukwa mu kutembenuka zosafunika kuti neutralization, mu mankhwala ena.

catalysts Special imathandizira zochita mankhwala, koma musati bwanji mlingo mphamvu ya mamolekyulu zimavuta osati aithamangitse ndi mgwirizano mosiyanasiyana yosavuta. Othandizira kuyeretsedwa kulonjezedwa kwa zosakaniza multicomponent mitsinje mpweya flue. Kuyeretsa mpweya makampani ntchito ngati oxides catalysts chitsulo, mkuwa, chromium, cobalt, nthaka, pulatinamu ndi ena. zinthu izi kukonzedwa chothandizira thandizo aikidwa mkati unit riyakitala. M'pofunika kuwunika umphumphu wa kunja wosanjikiza chothandizira, mwinamwake kuyeretsedwa othandizira si anazindikira mu kudzaza zenera, ndi umuna zinthu zoipa mwina Opyola malire chovomerezeka.

Lamulo lalikulu ndi chothandizira kwa - mtendere wa dongosolo pa zotani. Fufuzani ndi kupanga catalysts si abwino ntchito yaitali komanso wotchipa kwambiri, ndi movutikira, zomwe zimasokoneza ntchito njira othandizira. catalysts Modern kale selectivity ndi ntchito, kukana kutentha ndi mphamvu mawotchi.

Industrial catalysts chopangidwa mu mawonekedwe a zotchinga ndi mphete uchi. Ali ndi nthenda yotaya kukaniza otsika ndi mkulu kunja m'dera pamwamba. The kaŵirikaŵiri ntchito othandizira kuyeretsedwa mpweya mu chothandizira lokhazikika.

Makampani angathe kugwiritsa ntchito njira ziwiri mwapadera njira mpweya mankhwala - n'kupuma ndi nonstationary mode chongopeka analenga. The kusintha kwa ntchito chakhala chikugwiritsidwa ntchito njira ndi chifukwa wosakhazikika ndondomeko apamwamba processability, kuwonjezera mitengo anachita, kuwonjezera selectivity, njira kuchepetsa mowa mphamvu, kucheperachepera ndalama likulu unsembe ndi kuchepetsa ndalama zake opaleshoni.

The malangizo chachikulu cha chitukuko cha njira othandizira ndi kupereka catalysts wotchipa angathe kugwira ntchito pa otsika kutentha ndi kukhala kugonjetsedwa ndi zinthu zosiyanasiyana. Pakuti woipa pansipa 1 g / m³ ndi mabuku lalikulu la kutsukidwa mpweya thermocatalytic njira kumafuna zopatsa mphamvu ndi kuchuluka kwa chothandizira, choncho m'pofunika kukhala pazipita njira mphamvu zopulumutsa ndi zida zofuna mtengo wotsika likulu.
