Scrubbing Liquid Concentration Minitoring in Phosgene Gas Scrubbing

Kutsuka kwa PhosgeneNdi njira yofunika kwambiri yochotsera mpweya woopsawu kuchokera ku utsi wa mafakitale, kuteteza antchito, madera, ndi chilengedwe pamene akuonetsetsa kuti malamulo okhwima monga a Environmental Protection Agency (EPA) atsatiridwa.

Chofunika kwambiri pa ndondomekoyi ndichoyezera kuchuluka kwa madzi otsukira, chipangizo chomwe chimayang'anira kuchuluka kwa madzi otsukira monga sodium hydroxide (NaOH) kuti asunge kuyamwa bwino. Mwa kupewa mavuto monga kusasungunuka bwino kapena kusasungunuka kwambiri, mita iyi imathandizira magwiridwe antchito amakina otsukira mpweya.

Lonnmeter, kampani yotsogola komanso yodziwa bwino ntchito zopanga masensa anzeru, imachita bwino kwambiri popanga masensa olimba a mafakitale kuti iwonjezere kuchuluka kwa makina opangira zinthu. Kaya ndinu wopangawopanga isocyanate,wopanga polycarbonatekapena kusamaliramalo oyendetsera zinyalala, Lonnmeter inline concentration meter ndi njira zothandiza kwambiri popititsa patsogolo magwiridwe antchito ndikuchepetsa ndalama.

Kumvetsetsa Kutsuka kwa Phosgene Gas

Kutsuka kumaphatikizapo kutulutsa mpweya wokhala ndi phosgene kudzera munsanja yotsukira gasikapena dongosolo kumene madzi, omwe nthawi zambiri NaOH, amachotsa kapena kuyamwa mpweya, n’kuusandutsa mankhwala otetezeka monga sodium carbonate (Na₂CO₃) ndi sodium chloride (NaCl). Kugwira ntchito bwino kwa njirayi kumadalira kusunga kuchuluka koyenera kwa madzi otsukira, komwe ndi komwezoyezera kuchuluka kwa madzikusewera gawo lofunika kwambiri.

N’chifukwa Chiyani Kutsuka kwa Phosgene Gas Kuli Kofunika?

Kutsuka ndi mpweya wa phosgenendikofunikira pazifukwa zingapo:

Chitetezo:Kuchuluka kwa phosgene m'thupi pamlingo wochepera 3–5 ppm kungayambitse kukwiya kwa kupuma, pomwe kuchuluka kwakukulu kumayambitsa kutupa m'mapapo. Kutsuka kumateteza ogwira ntchito ndi anthu ammudzi.

Kutsatira Malamulo:Malamulo okhwima, monga ochokera ku EPA, amalamula kuti pakhale kuyang'anira ndi kuwongolera mpweya wa phosgene kuti ateteze chilengedwe.

Chitetezo cha Zachilengedwe:Kutulutsa kwa phosgene kosalamulirika kumatha kuipitsa mpweya ndi madzi, zomwe zingawononge chilengedwe.

Kupitiriza kwa Ntchito:Kutsuka bwino kumateteza kulephera kwa makina, zomwe zimapangitsa kuti ntchito ichitike mosalekeza.

Zotsukira Zoopsa Kutsuka Gasi wa Phosgene

Zotsukira za Caustic zimagwiritsidwa ntchito kwambirikutsuka kwa phosgenechifukwa cha kuphweka kwawo komanso kugwira ntchito bwino. Amagwira ntchito podutsa mpweya wa phosgene kudzera mu mzere wodzaza ndi NaOH, womwe umachitapo kanthu popanga Na₂CO₃, NaCl, ndi madzi. Mfundo zazikulu ndi izi:

Kuwunika Kukhazikika:Kuchuluka kwa NaOH kuyenera kusungidwa mkati mwa 5–20 wt% kuti zitsimikizire kuyamwa bwino.

Kusamalira Kutentha:Kuyankha kwa exothermic kumapanga kutentha, komwe kumafuna njira yozizira.

Kuchuluka kwa Mchere:Ma NaCl ambiri kapena Na₂CO₃ (5–30 wt%) angayambitse kupangika kwa makristalo, zomwe zimapangitsa kuti mchere uchotsedwe kuti chitetezo cha mthupi chisatseke.

Kuchuluka kwa ntchito:Mapampu osungira ndi magetsi ofunikira pa nthawi yadzidzidzi amatsimikizira kuti ntchito ikugwira ntchito mosalekeza.
