Yintoni ekufuneka iqwalaselwe xa kugcinwa i-ethylene oxide?

I-ethylene oxideyi-organic compound enefomyula yeekhemikhaliC2H4OYi-carcinogen enobuthi kwaye isetyenziselwa ukwenza iifungicides. I-ethylene oxide iyatsha kwaye iyaqhuma, kwaye akulula ukuyithutha kumgama omde, ngoko ke inoburhalarhume obukhulu kwindawo ethile.

Yintoni endifanele ndiyiqwalasele xa ndigcina i-ethylene oxide?

I-ethylene oxideigcinwa kwiitanki ezingqukuva, kwaye iitanki ezingqukuva zigcinwa efrijini, kwaye ubushushu bokugcina bungaphantsi kwama-degrees ali-10. Ekubeni i-ring B ine-flash point ephantsi kakhulu kwaye iyazidubula, kukhuselekile ukuyigcina efrijini.
1. Itanki ethe tyaba (isitya soxinzelelo), i-Vg=100m3, i-cooler eyakhelwe ngaphakathi (ijakethi okanye uhlobo lwe-coil yangaphakathi, enamanzi abandayo), itywinwe yi-nitrogen. I-insulation ene-polyurethane block
2. Uxinzelelo lokucwangcisa luthatha ixabiso eliphezulu loxinzelelo lwenkqubo yokubonelela nge-nitrogen (EOindawo yokugcina kunye ne-nitrogen seal aziyi kuchaphazela ubunyulu bayo, kwaye zinokunciphisa ngempumelelo umngcipheko wokuqhuma).
3. I-cooler eyakhelwe ngaphakathi: Yi-tube bundle (okanye i-core) ye-U-tube heat exchanger. Icetywe ukuba ibe luhlobo olususwayo, olulungele ukulungiswa nokutshintshwa.
4. Ikhoyili yokupholisa eyakhelwe ngaphakathi ilungisiwe: umbhobho wokupholisa wenyoka ngaphakathi kwitanki yokugcina awunakususwa.
5. Indawo yokupholisa: akukho mahluko, zonke ngamanzi abandayo (isixa esithile sesisombululo samanzi se-ethylene glycol).
