Phosgene ukukhuhlakuyinqubo ebucayi yokususa le gesi eyingozi ekhishwa yizimboni, ukuvikela abasebenzi, imiphakathi, kanye nemvelo kuyilapho kuqinisekiswa ukuthotshelwa kwemithetho eqinile efana naleyo evela ku-Environmental Protection Agency (EPA).
Okubalulekile kule nqubo yi-ukukhuhla imitha yokugxilisa uketshezi, idivayisi eqapha ukugcwala koketshezi lokukhuhla njenge-sodium hydroxide (NaOH) ukuze kugcinwe ukumuncwa okulungile. Ngokuvimbela izinkinga ezifana nokuncishiswa kancane noma ukuhlanzwa ngokweqile, lawa mamitha athuthukisa ukusebenza kweamasistimu wokukhuhla igesi.
I-Lonnmeter, umkhiqizi ohamba phambili nonamava wezinzwa zezinqubo ezihlakaniphile, wenza kahle kakhulu ekukhiqizeni izinzwa zenqubo yezimboni ezihlala isikhathi eside ukuze kuthuthukiswe izinga lokuzenzakalelayo lomugqa wokukhiqiza ohlanganisayo. Noma ngabe uyi-umkhiqizi we-isocyanate,umkhiqizi we-polycarbonate, noma uphathe aindawo yokuphatha imfucuza, Imitha yokugxilisa ye-Lonnmeter esemgqeni iyizixazululo zokuthuthukisa ukusebenza kahle nokunciphisa izindleko.
Ukuqonda i-Phosgene Gas Scrubbing
Ukukhuhla kubandakanya ukudlulisa igesi equkethe i-phosgene ku-aumbhoshongo wokukhuhla igesinoma isistimu lapho uketshezi, ngokuvamile i-NaOH, lunciphisa noma lumunca igesi, luyiguqule libe izinhlanganisela eziphephile njenge-sodium carbonate (Na₂CO₃) ne-sodium chloride (NaCl). Ukusebenza kwale nqubo kuncike ekugcineni ukugxila okulungile koketshezi lokukhuhla, okuyilaphoukukhuhla amamitha okugxilisa uketshezidlala indima ebalulekile.
Kungani I-Phosgene Gas Scrubbing Idingeka?
Phosgene gas ukukhuhlakubalulekile ngenxa yezizathu eziningana:
Ukuphepha:Ukuchayeka kwe-Phosgene ekugxileni okuphansi njengo-3–5 ppm kungabangela ukucasuka kokuphefumula, kuyilapho amazinga aphezulu eholela edema yamaphaphu. Ukukhuhla kuvimbela ukuchayeka kwabasebenzi nomphakathi.
Ukuthobela Umthetho:Imithetho eqinile, njengaleyo evela ku-EPA, igunyaza ukuqapha nokulawula ukukhishwa kwe-phosgene ukuze kuvikelwe imvelo.
Ukuvikelwa Kwemvelo:Ukukhishwa kwe-phosgene okungalawulwa kungangcolisa umoya namanzi, kulimaza imvelo.
Ukuqhubeka Kokusebenza:Ukukhuhla okusebenzayo kuvimbela ukwehluleka kwesistimu, kuqinisekisa ukukhiqizwa okungaphazamiseki.
I-Caustic Scrubbers ye-Phosgene Gas Scrubbing
I-Caustic scrubber isetshenziswa kabanziukukhuhla phosgenengenxa yobulula nokusebenza kwazo. Asebenza ngokudlulisela igesi ye-phosgene kukholamu egcwele egcwele i-NaOH, esabela kwakheka i-Na₂CO₃, NaCl, namanzi. Okucatshangelwayo okubalulekile kuhlanganisa:
I-Concentration Monitoring:Ukugxila kwe-NaOH kufanele kugcinwe ngaphakathi kwe-5-20 wt% ukuze kuqinisekiswe ukumuncwa okusebenzayo.
Ukuphatha Ukushisa:Ukusabela kwe-exothermic kukhiqiza ukushisa, okudinga isistimu yokupholisa.
Ukwakhiwa kukasawoti:Amazinga aphezulu e-NaCl noma e-Na₂CO₃ (5–30 wt%) angabangela ukucwebezela, okudinge ukukhishwa kukasawoti ukuze kuvinjelwe ukuvinjelwa kwesistimu.
Ukungafuneki:Amaphampu ayisipele kanye nempahla yamandla ephuthumayo iqinisekisa ukusebenza okuqhubekayo.
Iqhaza Lokukhuhla Amamitha Okugxilisa Uketshezi
Zisebenza Kanjani?
Ukukhuhla amamitha okugxilisa uketshezilinganisa ukugxila kwe-NaOH, NaCl, ne-Na₂CO₃ ngesikhathi sangempela, uqinisekise ukumuncwa okulungileamasistimu wokukhuhla igesi. Ngokusebenzisa ubuchwepheshe be-ultrasonic, lawa mamitha ahlaziya isivinini se-sonicmanufacuhlobod nge Lonnmeterukunquma ukugxila.
Inzwa yokucwiliswa yemitha ivamise ukufakwa kumapayipi e-DN 80 phakathi kwethangi lokukhuhla kanye nokuvuselela, ahlanganiswe nezinhlelo zokulawula zokulungiswa okuzenzakalelayo.
Izicelo ku-Phosgene Scrubbing
Ukuqapha Okusemgqeni:Iqinisekisa ukwakheka koketshezi okungaguquki ngesikhathi sokukhuhla.
Ukulawula Inqubo:Ilungisa ngokuzenzakalela umthamo we-NaOH noma ukukhishwa kukasawoti ukuze kuvinjelwe ukucwebezela.
Ukuphathwa Kwemfucuza:Ihlola okuqukethwe kwamakhemikhali ayinsalela ukuze kugaywe kabusha noma kulahlwe.
Izinzuzo Zokukhuhla Ukulinganisa Ukugxila Koketshezi
Ukuphepha Okuthuthukisiwe
Ukukhuhla isilinganiso sokugxilisa uketsheziiqinisekisa ukuthi uketshezi lokukhuhla luhlala lusebenza kahle, lunciphisa ubungozi bokuphumelela kwe-phosgene. Lokhu kubalulekile ukuze kuvikelwe abasebenzi nemiphakathi ekuchayekeni kule gesi enobuthi obuyingozi kakhulu.
Ukuthobela Umthetho
Izimboni kufanele zithobele imithetho eqinile, efana naleyo evela ku-EPA kanye ne-OSHA. Amamitha okugxilisa ingqondo ahlinzeka ngedatha enembile, yesikhathi sangempela yokubika ukungcola, ukwenza kube lula ukuhlola nokugwema izinhlawulo.
Ukusebenza Ngempumelelo
Ukuqapha ngesikhathi sangempela kuvimbela ukungasebenzi okubangelwa ukugxila okungalungile, ukunciphisa isikhathi sokuphumula kwesistimu kanye nezidingo zokunakekelwa. Isibonelo, imboni yamakhemikhali yonga ihora elingu-1 nsuku zonke ezindlekweni zabasebenzi ngokwenza amasheke okugxilisa ingqondo ngokuzenzakalela.
Ukonga Izindleko
Ngokuthuthukisa ukusetshenziswa kwe-NaOH nokuvimbela ukuncishiswa kwe-dilution ngokweqile,ukukhuhla amamitha okugxilisa uketsheziukunciphisa udoti kanye nezindleko zokugcwalisa, kunikeze ukonga okubalulekile kokusebenza kwevolumu ephezulu.
Izici Zobuchwepheshe Nokuhlanganiswa
Ukufakwa nokusebenza
Ukukhuhla amamitha okugxilisa uketsheziafakwe emapayipini noma emathangeni, kusetshenziswa izinzwa eziqinile ezenziwe ngezinto ezihlala isikhathi eside ukuze zimelane nezindawo ezigqwalile. Zihlanganisa nezinhlelo ze-PLC/DCS zokulawula okuzenzakalelayo, ziqinisekisa ukulungiswa kwesikhathi sangempela ukuze kugcinwe ukugxila okuhle.
