Nhanganyaya: Munguva pfupi yapfuura, zvidyarwa zvemumba ethylene glycol zvave kutenderera pakati pekutangazve kwemarasha kemikari indasitiri uye yakasanganiswa kugadzirwa kweshanduko.Shanduko dzekutanga-kwezvidyarwa zviripo zvakakonzera chiyero chekugovera uye kudiwa mumusika kuchinja zvakare mune inotevera nhanho.
Coal Chemical Industry - Multiple Restart Plans
Parizvino, mutengo wemarasha muzviteshi zvemumba unoshanduka uchitenderedza 1100. Kubva pakuona kwekubatsira kwehupfumi, zvirimwa zvemugodhi wemarasha epamba uye kunze kwenyika zvichiri mukurasikirwa, asi zvimwe zvinomera zvichine zvirongwa zvekutangazve zvichienderana nemaonero emidziyo.

Kubva paurongwa hwechigadzirwa chazvino, michina yakati wandei yakavharwa gore rapfuura yave kutangwazve neHongsifang, Huayi, Tianye, uye Tianying;Muchikamu chekupedzisira, Henan naGuanghui vanewo zvirongwa zvekutangazve;Mushure mekugadzirisa muna Kurume, Guizhou Qianxi inoronga kutangazve kutanga kwaKubvumbi.Urongwa hwekugadzirisa huripo hwaApril hausi pakati.Pamusoro peiyo 1.8 miriyoni matani matani ekuremerwa kweShaanxi Coal, iyo yakazara marasha makemikari chirongwa cheKubvumbi chinotarisirwa kunge chiri matani mazana mana ezviuru.
Kubatanidzwa - chikamu chemari, chikamu chekushandura chichiri pasi pekucherechedza
Iko kutendeuka kwechinyakare kunonyanya kuenderana nekugadzirwa kweiyo ethylene oxide/ethylene glycol.Mutengo wezvino we ethylene oxide wakapoteredza 7200. Kubva pakuona kwekuenzanisa kwemutengo, hupfumi hwehupfumi hwekubudisa ethylene oxide ikozvino huri nani kune ethylene glycol.Nekudaro, nekuda kwekugumira kwekuchengetedza ethylene oxide uye yazvino flat kudiwa kwemvura inodzikisa agent monomers, mabhizinesi mazhinji anoona kuwedzera kwemitengo mu ethylene oxide asi kutengesa kunodzikiswa.Naizvozvo, mukana wekuwedzera ethylene oxide kugadzirwa nekudzvanya ethylene glycol muchikamu chekupedzisira chemaitiro echinyakare madhizaini mashoma.
Nekumisikidzwa kwakasiyana-siyana kwekunatsa uye zvidyarwa zvemakemikari, zvigadziriso zvakagadziridzwa zvakagadzirirwa kudzika kusarudzwa kwe ethylene mumatatu makuru ekunatsa mudzimba uye makemikari akabatanidzwa zvidyarwa mune inotevera nhanho.Semuyenzaniso, kuwedzera ethylene oxide uchizvibatanidza kudzika pasi, kuwedzera styrene, vinyl acetate, uye zvimwe zvigadzirwa kuenzanisa ethylene kushandiswa.Muna Kubvumbi, iyo inorema kunatsa uye makemikari anogara achimanikidza kuchengetedza, Zhejiang Petrochemical, uye satellite kuderedzwa kwemutoro zvishoma nezvishoma zvakaonekwa, asi iyo chaiyo dhigirii yekuziva ichiri kuda kujekeswa.
Kuvakwa kwemidziyo mitsva kunogona kunonoka
mufananidzo
Parizvino, Sanjiang neYuneng Chemical vane chokwadi chepamusoro chekuisa michina mitsva mukugadzira;Iko mukana wekuti kugadzira kunotemerwa mushure mepakati pegore.Ikozvino hapana chirongwa chakajeka chekugadzira chemamwe maturusi.
Zvichienderana neazvino eparutivi shanduko uye zvirongwa zvechirimwa zveramangwana, zvinotarisirwa kuti kugadzirwa kwepolyester kucharamba kwakagadzikana kubva munaKurume kusvika Kubvumbi.Zvinotarisirwa kuti pachange pachine tarisiro yekudzikisa kubva pakuona kwehutano hwemagariro evanhu, asi huwandu hwese hwekugadzirisa hushoma.
