Mau Oyamba: Posachedwapa, zomera zapakhomo za ethylene glycol zakhala zikusintha pakati pa kuyambiranso kwa makampani amagetsi a malasha ndi kutembenuka kophatikizana.Kusintha kwa kuyambika kwa zomera zomwe zilipo kale kwachititsa kuti chiwerengero cha zinthu ndi zofunikira pamsika zisinthe kachiwiri pambuyo pake.
Makampani a Chemical Chemical - Mapulani Ambiri Oyambitsanso
Pakalipano, mtengo wa malasha m'madoko apanyumba umasinthasintha mozungulira 1100. Kuchokera pakuwona phindu lachuma, zomera zapanyumba ndi zakunja za migodi ya malasha zidakalibe vuto, koma zomera zina zimakhalabe ndi ndondomeko zoyambiranso malinga ndi momwe zipangizo zimagwirira ntchito.

Kuchokera pa ndondomeko yamakono yamakono, zipangizo zingapo zomwe zinatsekedwa chaka chatha tsopano zayambikanso ndi Hongsifang, Huayi, Tianye, ndi Tianying;Pamapeto pake, Henan ndi Guanghui ali ndi mapulani oyambiranso;Pambuyo pakukonzanso mu Marichi, Guizhou Qianxi akukonzekera kuyambiranso koyambirira kwa Epulo.Dongosolo lokonzekera lomwe lilipo la Epulo silinakhazikitsidwe pakati.Kuphatikiza pa kuchuluka kwa matani 1.8 miliyoni a Shaanxi Coal, dongosolo lonse lopanga mankhwala a malasha a Epulo likuyembekezeka kukhala pafupifupi matani 400000.
Kuphatikiza - kubweza ndalama pang'ono, kutembenuka pang'ono kumawonedwabe
Kutembenuka kwachikhalidwe kumakhazikitsidwa makamaka pakupanga malamulo a ethylene oxide/ethylene glycol.Mtengo wamakono wa ethylene oxide uli pafupi ndi 7200. Kuchokera pakuwona kufanana kwa mtengo, phindu lachuma la kupanga ethylene oxide panopa ndi lopambana kuposa la ethylene glycol.Komabe, chifukwa cha kuchepa kwa kusungirako kwa ethylene oxide komanso kufunikira kwaposachedwa kwa ma monomers ochepetsera madzi, mabizinesi ambiri amawona kuwonjezeka kwamitengo ya ethylene oxide koma kugulitsa kumalephereka.Choncho, mwayi wowonjezera ethylene oxide kupanga ndi compressing ethylene glycol mu siteji yotsatira ya zipangizo chikhalidwe ndondomeko ndi ochepa.
Ndi masanjidwe osiyanasiyana azomera zazikulu zoyenga ndi mankhwala, masinthidwe okhathamiritsa apangidwa kuti azitha kusankha bwino m'malo otsetsereka a ethylene muzomera zitatu zazikuluzikulu zoyenga m'nyumba komanso zophatikizika ndi mankhwala pambuyo pake.Mwachitsanzo, kuonjezera ethylene oxide pamene kudzisakaniza kunsi kwa madzi, kuwonjezera styrene, vinyl acetate, ndi zinthu zina kuti mugwirizanitse ethylene kumwa.Mu Epulo, kuyenga kolemetsa komanso kukonza kwamphamvu kwamankhwala, Zhejiang Petrochemical, ndi kuchepetsa katundu wa satana pang'onopang'ono anazindikira, koma kutsimikizika kwenikweni kumafunikira kufotokozedwanso.
Kupanga kwa zida zatsopano kungachedwe
chithunzi
Pakalipano, Sanjiang ndi Yuneng Chemical ali ndi chitsimikizo chachikulu choyika zipangizo zatsopano pakupanga;Kuthekera kwakuti kupanga kumatsimikiziridwa pakatha pakati pa chaka.Pakalipano palibe ndondomeko yomveka yopangira zipangizo zina.
Kutengera kusintha komwe kulipo komanso mapulani amtsogolo azomera, tikuyembekezeka kuti kupanga poliyesitala kumakhala kokhazikika kuyambira Marichi mpaka Epulo.Zikuyembekezeredwa kuti padzakhalabe chiyembekezero cha destocking kuchokera pamalingaliro a chikhalidwe cha anthu, koma chiwerengero chonse cha destocking ndi chochepa.
