Phosgene ukukhuhlayinkqubo ebaluleke kakhulu yokususa le gesi eyingozi ekukhutshweni kwamashishini, ukukhusela abasebenzi, uluntu, kunye nokusingqongileyo ngelixa uqinisekisa ukuthotyelwa kwemimiselo engqongqo njengaleyo evela kwi-Arhente yoKhuseleko lweNdalo (EPA).
Okungundoqo kule nkqubo kukuukukhuhla imitha yoxinaniso yolwelo, isixhobo esijonga ingxinano yolwelo lokukhuhla njenge sodium hydroxide (NaOH) ukugcina ukufunxwa okugqibeleleyo. Ngokuthintela imiba enje ngoku-dilution okanye uku-dilution ngokugqithisileyo, ezi mitha ziphucula ukusebenza kweiinkqubo zokukhuhla igesi.
I-Lonnmeter, umvelisi okhokelayo kunye namava kwiisenso zenkqubo ezikrelekrele, uyagqwesa ekuveliseni iisensom zenkqubo yoshishino elomeleleyo ukuphucula inqanaba lokuzenzekelayo lomgca wemveliso odibeneyo. Nokuba uyi-umvelisi we-isocyanate,umenzi wepolycarbonate, okanye ulawule aindawo yolawulo lwenkunkuma, Imitha yoxinaniso ye-Lonnmeter ikwizisombululo zokuphucula ukusebenza kakuhle kunye nokunciphisa iindleko.
Ukuqonda iPhosgene Gas Scrubbing
Ukukhuhla kubandakanya ukugqithiswa kwegesi ene-phosgene kwi-ainqaba yokukhuhla igesiokanye inkqubo apho ulwelo, ngokuqhelekileyo i-NaOH, i-neutralize okanye ifunxa igesi, iguqulela kwiikhompawundi ezikhuselekileyo njenge-sodium carbonate (Na₂CO₃) kunye ne-sodium chloride (NaCl). Ukusebenza kwale nkqubo kuxhomekeke ekugcineni ugxininiso oluchanekileyo lwe-scrubbing liquid, aphoukukhuhla iimitha zoxinaniso zolwelodlala indima ebalulekileyo.
Kutheni iPhosgene Gas Scrubbing iyimfuneko?
Ukukhuhlwa kwerhasi yePhosgenekubalulekile ngenxa yezizathu ezininzi:
Ukhuseleko:Ukubonakaliswa kwe-Phosgene kwiindawo eziphantsi njenge-3-5 ppm kunokubangela ukucaphuka kokuphefumula, ngelixa amanqanaba aphezulu akhokelela kwi-edema ye-pulmonary. Ukukhuhla kuthintela ukuchaneka kwabasebenzi kunye noluntu.
Ukuthotyelwa koMgaqo:Imimiselo engqongqo, efana naleyo evela kwi-EPA, igunyazisa ukubeka iliso kunye nokulawula ukukhutshwa kwe-phosgene ukukhusela okusingqongileyo.
