Kumvetsetsa Phosgene Gasi Scrubbing
Kukolopa kumaphatikizapo kupatsira mpweya wokhala ndi phosgene kudzera mu agasi scrubbing Towerkapena kachitidwe komwe madzi, nthawi zambiri NaOH, amalepheretsa kapena kuyamwa gasi, kuwasandutsa zinthu zotetezeka monga sodium carbonate (Na₂CO₃) ndi sodium chloride (NaCl). Kuchita bwino kwa njirayi kumadalira kusunga ndende yolondola yamadzi otsukira, komwe kulikupukuta madzi ndende mitagwira ntchito yofunika kwambiri.
Chifukwa chiyani Phosgene Gas Scrubbing Ndi Yofunika?
Phosgene gasi kutsukandizofunikira pazifukwa zingapo:
Chitetezo:Kuwonekera kwa phosgene pazigawo zotsika kwambiri ngati 3-5 ppm kungayambitse kupsa mtima, pomwe milingo yayikulu imayambitsa pulmonary edema. Kukolopa kumalepheretsa kuwonekera kwa ogwira ntchito ndi anthu ammudzi.
Kutsata Malamulo:Malamulo okhwima, monga a EPA, amalamula kuyang'anira ndi kuwongolera mpweya wa phosgene kuteteza chilengedwe.
Chitetezo Chachilengedwe:Kutulutsa kwa phosgene kosalamulirika kumatha kuipitsa mpweya ndi madzi, kuwononga zachilengedwe.
Kupitiliza kwa Ntchito:Kukolopa kogwira mtima kumalepheretsa kulephera kwadongosolo, kuwonetsetsa kupanga kosalekeza.
Caustic Scrubbers kwa Phosgene Gas Scrubbing
Caustic scrubbers amagwiritsidwa ntchito kwambiriphosgene scrubbingchifukwa cha kuphweka kwawo komanso kuchita bwino. Amagwira ntchito podutsa mpweya wa phosgene kudzera pamzere wodzaza ndi NaOH, womwe umachita kupanga Na₂CO₃, NaCl, ndi madzi. Zolinga zazikulu ndi izi:
Kuwunika Kwambiri:Kuphatikizika kwa NaOH kuyenera kusungidwa mkati mwa 5-20 wt% kuti zitsimikizire kuyamwa moyenera.
Kuwongolera Kutentha:The exothermic reaction imatulutsa kutentha, kumafuna dongosolo lozizirira.
Kumanga mchere:Mlingo wapamwamba wa NaCl kapena Na₂CO₃ (5-30 wt%) ungayambitse crystallization, kufunikira kuchotsedwa kwa mchere kuti zisatseke dongosolo.
Zosafunika:Mapampu osunga zobwezeretsera ndi zida zamagetsi zamagetsi zimatsimikizira kugwira ntchito mosalekeza.
