Nokuba ungumntu osebenza kwi-intanethiumvelisi we-isocyanate,umenzi we-polycarbonateokanye ulawuleindawo yolawulo lwenkunkumaImitha yokulinganisa uxinano lweLonnmeter zizisombululo ezisetyenziswa kakhulu ukuphucula ukusebenza kakuhle nokunciphisa iindleko.
Ukuqonda ukuCoca iPhosgene Gas
Ukukhuhla kubandakanya ukudlulisa igesi equlethe i-phosgene kwi-ainqaba yokucoca igesiokanye inkqubo apho ulwelo, oluqhele ukuba yiNaOH, luyitshintsha okanye lufunxa igesi, luyiguqule ibe ziikhompawundi ezikhuselekileyo ezifana nesodium carbonate (Na₂CO₃) kunye nesodium chloride (NaCl). Ukusebenza kwale nkqubo kuxhomekeke ekugcineni uxinaniso oluchanekileyo lolwelo lokuhlikihla, aphoiimitha zoxinzelelo lolwelo lokuhlafunabadlale indima ebalulekileyo.
Kutheni iPhosgene Gas Scrubbing iyimfuneko?
Ukucocwa ngegesi yePhosgenekubalulekile ngezizathu ezininzi:
Ukhuseleko:Ukuvezwa kwe-phosgene kumanqanaba aphantsi njenge-3–5 ppm kunokubangela ukurhawuzelelwa kokuphefumla, ngelixa amanqanaba aphezulu ekhokelela ekudumbeni kwamaphaphu. Ukukhuhla kuthintela ukuvezwa kwabasebenzi kunye noluntu.
Ukuthobela iMithetho:Imithetho engqongqo, efana naleyo ivela kwi-EPA, iyalela ukuba kubekwe esweni kwaye kulawulwe ukukhutshwa kwe-phosgene ukuze kukhuselwe okusingqongileyo.
Ukhuseleko lweNdalo:Ukukhutshwa kwe-phosgene okungalawulwayo kunokungcolisa umoya namanzi, konzakalise iinkqubo zendalo.
Ukuqhubeka kokusebenza:Ukukhuhla kakuhle kuthintela ukusilela kwenkqubo, kuqinisekisa imveliso engaphazanyiswayo.
Izihluzi zeCaustic yokucoca iPhosgene Gas
Ii-scrubbers ze-Caustic zisetyenziswa kakhulu kwiukuhlafuna nge-phosgenengenxa yobulula nokusebenza kwazo. Zisebenza ngokudlulisa igesi ye-phosgene kwikholamu egcweleyo egcwele i-NaOH, ethi iphendule ekwenzeni i-Na₂CO₃, i-NaCl, kunye namanzi. Izinto ezibalulekileyo ekufuneka ziqwalaselwe ziquka:
Ukubeka iliso ekugxileni:Uxinzelelo lweNaOH kufuneka lugcinwe ngaphakathi kwe-5–20 wt% ukuqinisekisa ukufunxwa okusebenzayo.
Ulawulo lobushushu:Impendulo exothermic ivelisa ubushushu, nto leyo edinga inkqubo yokupholisa.
Ukwakheka kweTyuwa:Amanqanaba aphezulu e-NaCl okanye e-Na₂CO₃ (5–30 wt%) anokubangela i-crystallization, nto leyo enokubangela ukuba ityuwa isuswe ukuze kuthintelwe ukuvaleka kwenkqubo.
Ukuphinda kusetyenziswe imali:Iimpompo zokuxhasa kunye nezixhobo zamandla ezingxamisekileyo ziqinisekisa ukusebenza rhoqo.
