Acetylene (C2H2) ndi mpweya wofunikira wamakampani omwe amagwiritsidwa ntchito kwambiri pamakampani opanga mankhwala, zitsulo, chithandizo chamankhwala, firiji ndi kuwotcherera. Kupanga kwake kumapangidwa makamaka kuchokera kuzinthu zopangira pogwiritsa ntchito mankhwala. M'makampani, kupanga acetylene nthawi zambiri kumadalira ma jenereta a acetylene kuti apange mpweya wa acetylene wapamwamba kwambiri kudzera muzochita zosiyanasiyana zamankhwala. Jiangsu Huazhong amayambitsa njira yopangira acetylene kuti ikuthandizeni kumvetsetsa momwe mbewu za acetylene zimapangira mpweya wofunikirawu.

Zopangira zopangira acetylene
Kupanga acetylene kumafuna zipangizo monga laimu (CaCO3) ndi coke (C). Limestone ndiye maziko opangira calcium hydroxide ndi carbon dioxide, ndipo coke imagwiritsidwa ntchito popereka mpweya. Panthawi yopanga acetylene, zopangira izi zimapanga mpweya wa acetylene kudzera pakutentha kwambiri komanso kusintha kwamankhwala.

Njira yopanga acetylene
Pali njira ziwiri zazikulu zopangira acetylene: Njira ya Carbide ndi njira ya jenereta ya acetylene. Mwa iwo, Njira ya Carbide ndiyo njira yodziwika kwambiri yopanga.

Njira ya Karl-Haim
Njira ya Karl-Haim ndiyo njira yomwe imagwiritsidwa ntchito kwambiri popanga acetylene m'makampani. Njirayi imagwiritsa ntchito miyala yamchere ndi coke monga zopangira, ndipo imapanga calcium hydroxide (Ca (OH) 2) ndi carbon dioxide (CO2) kupyolera mu ng'anjo yamagetsi yotentha kwambiri. Kashiamu hydroxide ndiyeno imachita ndi madzi kupanga calcium hydroxide slurry, yomwe imalumikizana ndi calcium carbonate kupanga acetylene.

Njira yeniyeni ndi iyi:

Mwala wa laimu umatenthedwa ndi kutentha kwambiri kuti upange calcium oxide (CaO) ndi carbon dioxide (CO2).
Kashiamu oxide ndiyeno amakhudzidwa ndi madzi kupanga calcium hydroxide (Ca(OH)2).
Kenako, calcium hydroxide imakumana ndi calcium carbonate kupanga mpweya wa acetylene (C2H2) ndi calcium hydroxide.

Njira yopangira acetylene
Njira ya jenereta ya acetylene imapanga acetylene pochita ore kapena carbon raw materials ndi calcium hydroxide. Ubwino wa njirayi ndikuti mpweya wa acetylene wopangidwa ndi woyera ndipo ungagwiritsidwe ntchito kwambiri poyesera mankhwala ndi kupanga mafakitale.

Njira yoyeretsera acetylene
Pambuyo popanga acetylene, njira zingapo zoyeretsera zimafunikira kuti acetylene ikhale yabwino. Choyamba, ndi mpweya wa acetylene umaziziritsidwa ndikudutsa mu chipangizo chochapira madzi kuchotsa zonyansa. Kenako, mpweya wa acetylene umasefedwa kuchotsa tinthu tating'ono tolimba. Pomaliza, mpweyawo umayeretsedwanso ndi adsorbent kuti atsimikizire kuti chiyero cha acetylene chikugwirizana ndi muyezo.

Kusungirako ndi mayendedwe a acetylene
Popeza acetylene ndi mpweya woyaka komanso wophulika, chisamaliro chapadera chiyenera kulipidwa panthawi yosungira komanso yoyendetsa. Acetylene nthawi zambiri amasungidwa mu mawonekedwe a gasi woponderezedwa mu masilinda a gasi odzipereka. Panthawi yoyendetsa, masilinda a gasi a acetylene ayenera kukwaniritsa miyezo yotetezeka kuti ateteze kutayikira ndi ngozi zaphulika.

Kugwiritsa ntchito acetylene
Acetylene, monga zopangira zopangira mafakitale, amagwiritsidwa ntchito kwambiri m'magawo ambiri. Pankhani yowotcherera, acetylene imatha kutulutsa malawi otentha kwambiri akasakanikirana ndi okosijeni, omwe amagwiritsidwa ntchito kwambiri podula ndi kuwotcherera zitsulo. M'makampani opanga mankhwala, acetylene ndi chinthu chofunika kwambiri chopangira mankhwala osiyanasiyana, monga acetic acid, acrylonitrile, ethylene, ndi zina zotero.

Mapeto
Acetylene ndi gasi wofunikira komanso wofunikira m'makampani amakono. Kapangidwe ka gasi wa acetylene ndizovuta komanso zofewa, zomwe zimakhudzana ndi machitidwe amankhwala, kuyeretsa gasi, kusungirako ndi kuyendetsa. Ndi kupita patsogolo kwa sayansi ndi ukadaulo komanso ukadaulo wopitilira muyeso waukadaulo wopanga, gasi la acetylene nawonso nthawi zonse kukhathamiritsa ndondomeko kupanga acetylene kulimbikitsa chitukuko cha mafakitale osiyanasiyana kumlingo waukulu.
