A ranar 1 ga Yuli, 2022, bikin farawa na kashi na farko na ton 300,000methyl methacrylateAn gudanar da aikin MMA na Henan Zhongkepu Raw da New Materials Co., Ltd a yankin Ci gaban Tattalin Arziki da Fasaha na Puyang, wanda ke nuna aikace-aikacen farko na sabon saitin fasahar ionic ruwa catalytic ethylene MMA da kanta ta haɓaka ta CAS da Zhongyuan Dahua.Wannan kuma ita ce shukar ethylene MMA ta farko da aka buga a China.Idan aka samu nasarar shigar da na'urorin wajen kera su, za a samu ci gaba wajen samar da ethylene MMA na kasar Sin, wanda ke da matukar tasiri ga masana'antar MMA.
Nau'in MMA na biyu na tsarin ethylene a China ana iya yada shi a Shandong.Da farko ana sa ran za a sanya shi cikin samarwa a kusa da 2024, kuma a halin yanzu yana cikin matakin amincewa na farko.Idan naúrar ta kasance gaskiya, za ta zama na biyu na MMA na sarrafa ethylene a kasar Sin, wanda ke da matukar ma'ana ga bambance-bambancen tsarin samar da MMA a kasar Sin, da ci gaban masana'antar sinadarai ta kasar Sin.
Bisa ga bayanan da suka dace, akwai hanyoyin samar da MMA masu zuwa a kasar Sin: tsarin C4, tsarin ACH, ingantaccen tsarin ACH, tsarin BASF ethylene da Lucite ethylene tsari.A duk duniya, waɗannan hanyoyin samarwa suna da shigarwar masana'antu.A kasar Sin, dokar C4 da dokar ACH sun kasance masana'antu, yayin da dokar ethylene ba ta cika masana'antu ba.
Me yasa masana'antar sinadarai ta kasar Sin ke fadada masana'antar ta ethylene MMA?Shin farashin samar da MMA da hanyar ethylene ke samarwa yana yin gasa?
Na farko, masana'antar ethylene MMA ta haifar da sarari a cikin Sin kuma tana da babban matakin fasahar samarwa.Bisa ga binciken, akwai nau'ikan ethylene MMA guda biyu kawai a duniya, waɗanda ke cikin Turai da Arewacin Amurka bi da bi.Yanayin fasaha na sassan ethylene MMA suna da sauƙi.Adadin amfani da atomic ya fi 64%, kuma yawan amfanin ƙasa ya fi sauran nau'ikan tsari.BASF da Lucite sun gudanar da bincike na fasaha da haɓaka kayan aikin MMA don tsarin ethylene da wuri, kuma sun sami masana'antu.
Ƙungiyar MMA na tsarin ethylene baya shiga cikin albarkatun acidic, wanda kuma yana haifar da ƙananan lalata kayan aiki, tsarin samar da yanayi mai dacewa, da kuma tsawon lokacin aiki da sake zagayowar.A wannan yanayin, ƙimar ƙimar ƙimar MMA a cikin tsarin ethylene yayin aiki yana ƙasa da na sauran hanyoyin.
Kayan Ethylene MMA shima yana da rashin amfani.Na farko, ana buƙatar wuraren tallafi don tsire-tsire na ethylene, wanda galibi ana samar da ethylene ta hanyar haɗaɗɗun tsire-tsire, don haka ana buƙatar tallafawa ci gaban masana'antar haɗin gwiwa.Idan an saya ethylene, tattalin arzikin yana da talauci.Na biyu, akwai nau'ikan kayan aikin ethylene MMA guda biyu kawai a cikin duniya.Ayyukan da kasar Sin ke ginawa suna amfani da fasahar kwalejin kimiyya ta kasar Sin, kuma sauran kamfanoni ba za su iya samun fasahar cikin sauki da inganci ba.Na uku, kayan aikin MMA na tsarin ethylene yana da tafiyar matakai mai tsawo, babban ma'auni na zuba jari, babban adadin chlorine da ke dauke da ruwa mai tsabta za a samar da shi a cikin tsarin samar da kayan aiki, kuma farashin magani na sharar gida uku yana da yawa.
Na biyu, ƙimar farashin ƙungiyar MMA galibi ta fito ne daga ethylene mai goyan baya, yayin da ethylene na waje ba shi da fa'ida ta fa'ida.Dangane da binciken, sashin MMA na hanyar ethylene shine 0.4294 ton na ethylene, 0.387 ton na methanol, 661.35 Nm ³ iskar gas, 1.0578 ton na danyen chlorine ana samar da shi ta hanyar haɗin gwiwa, kuma babu wani samfurin methacrylic acid a cikin samarwa. .
Bisa ga dacewa data fito da Shanghai Yunsheng Chemical Technology Co., Ltd., da MMA kudin ethylene hanya ne game da 12000 yuan / ton lokacin da ethylene ne 8100 yuan / ton, methanol ne 2140 yuan / ton, roba gas ne 1.95 yuan /. Mita mai siffar sukari, kuma danyen chlorine ya kai yuan 600/ton.Idan aka kwatanta da lokaci guda, farashin doka na hanyar C4 da hanyar ACH suna da yawa.Saboda haka, bisa ga yanayin kasuwa na yanzu, ethylene MMA ba shi da wata fa'ida ta tattalin arziki.
Koyaya, samar da MMA ta hanyar ethylene mai yuwuwa yayi daidai da albarkatun ethylene.Ethylene ne m daga naphtha fatattaka, kwal kira, da dai sauransu. A wannan yanayin, da gasa na MMA samar da ethylene hanya za a yafi rinjayar da farashin ethylene raw kayan.Idan an samar da albarkatun ethylene da kansa, dole ne a ƙididdige shi bisa farashin farashin ethylene, wanda zai inganta ƙimar ƙimar ethylene MMA sosai.
Na uku, ethylene MMA yana cinye chlorine mai yawa, kuma farashi da alaƙar goyan bayan chlorine kuma za su ƙayyade mabuɗin ƙimar ƙimar ethylene MMA.Dangane da hanyoyin samar da BASF da Lucite, duka waɗannan hanyoyin suna buƙatar cinye adadin chlorine mai yawa.Idan chlorine yana da alaƙar goyan bayan ta, farashin chlorine baya buƙatar la'akari, wanda zai inganta ƙimar ƙimar ethylene MMA sosai.
A halin yanzu, ethylene MMA ya ja hankalin wasu musamman saboda gasa farashin samarwa da kuma yanayin aiki mai sauƙi na sashin.Bugu da kari, bukatu don tallafawa albarkatun kasa suma sun dace da yanayin ci gaban masana'antar sinadarai ta kasar Sin a halin yanzu.Idan kamfani yana goyan bayan ethylene, chlorine da iskar gas, to ethylene MMA na iya zama yanayin samar da MMA mafi tsada a halin yanzu.A halin yanzu, yanayin bunkasuwar masana'antar sinadarai ta kasar Sin, galibin kayayyakin tallafi ne.A karkashin wannan yanayin, hanyar ethylene da ta dace da ethylene MMA na iya zama abin da masana'antu ke mayar da hankali kan masana'antu.
