Musi waChikunguru 1, 2022, mhemberero yekutanga yechikamu chekutanga che300,000 toni.methyl methacrylate(inozonzi methyl methacrylate) chirongwa cheMMA cheHenan Zhongkepu Raw uye New Materials Co., Ltd. chakaitirwa muPuyang Economic and Technological Development Zone, ichimaka mashandisirwo ekutanga seti itsva yeionic liquid catalytic ethylene MMA tekinoroji yakazvimiririra. CAS uye Zhongyuan Dahua.Iyi zvakare ndiyo yekutanga ethylene MMA chirimwa chakaburitswa muChina.Kana iyo midziyo ikaiswa mukugadzirwa, inowana budiriro mukugadzirwa kweChina ethylene MMA, iyo ine simba rakakosha paindasitiri yeMMA.
Yechipiri MMA unit ye ​​ethylene process muChina inogona kushambadzirwa muShandong.Pakutanga inotarisirwa kuiswa mukugadzirwa kunosvika 2024, uye parizvino iri mudanho rekutanga rekubvumidzwa.Kana chikamu chiri chechokwadi, chichava chechipiri cheMMA unit ye ​​ethylene process muChina, iyo yakakosha zvikuru mukusiyana kweMMA kugadzirwa kwemaitiro muChina uye kusimudzira indasitiri yemakemikari yeChina.
Zvinoenderana nedata rakakodzera, kune anotevera MMA maitiro ekugadzira muChina: C4 maitiro, ACH maitiro, yakagadziridzwa ACH maitiro, BASF ethylene process uye Lucite ethylene process.Pasi rose, maitiro ekugadzira aya ane maindasitiri ekuisa.MuChina, mutemo weC4 uye mutemo weACH wakagadzirwa, asi mutemo we ethylene hauna kunyatsogadzirwa.
Nei indasitiri yemakemikari yeChina iri kuwedzera ethylene MMA chirimwa?Mutengo wekugadzira weMMA unogadzirwa ne ethylene nzira inokwikwidza here?
Chekutanga, iyo ethylene MMA chirimwa yakagadzira isina chinhu muChina uye ine yakakwirira yekugadzira tekinoroji level.Maererano neongororo, kune maviri chete seti ethylene MMA mauniti munyika, ayo ari muEurope neNorth America zvakateerana.Mamiriro ehunyanzvi ethylene MMA mayunitsi ari nyore.Chiyero chekushandiswa kweatomu chinodarika 64%, uye goho rakakwirira kupfuura mamwe marudzi emaitiro.BASF naLucite vakaita tsvakiridzo yehunyanzvi uye kuvandudza kweMMA michina ye ethylene process kare kare, uye vakawana maindasitiri.
Iyo MMA unit ye ​​ethylene process haibatanidzi mune acidic mbishi zvinhu, izvo zvakare zvinotungamira kune yakaderera kuora kwemidziyo, ine nharaunda-inoshamwaridzika yekugadzira maitiro, uye yakareba yakazara nguva yekushanda uye kutenderera.Muchiitiko ichi, kuderera kwemutengo weMMA unit mu ethylene process panguva yekushanda yakaderera pane yemamwe maitiro.
Ethylene MMA midziyo zvakare ine zvayakaipira.Kutanga, zvivakwa zvinotsigira zvemiti ye ethylene inodiwa, umo ethylene inonyanya kugadzirwa nemiti yakabatanidzwa, saka kutsigira kusimudzira kwemabhizinesi akabatanidzwa kunodiwa.Kana ethylene inotengwa, hupfumi hwakashata.Chechipiri, kune maviri chete seti ethylene MMA michina munyika.Mapurojekiti eChina ari kuvakwa anoshandisa tekinoroji yeChinese Academy yeSainzi, uye mamwe mabhizinesi haagone kuwana tekinoroji nyore uye nemazvo.Chechitatu, iyo MMA midziyo ye ethylene process ine nguva refu yekuyerera, hombe yekudyara chiyero, yakawanda yeklorini ine tsvina yemvura ichagadzirwa mukugadzira, uye mutengo wekurapa wemarara matatu wakakwira.
Chechipiri, kukwikwidzana kwemutengo weMMA unit kunonyanya kunobva kune inotsigira ethylene, nepo ethylene yekunze isina mukana wakajeka wekukwikwidza.Maererano nekuferefeta, iyo MMA unit ye ​​ethylene nzira ndeye 0.4294 matani ethylene, 0.387 matani emethanol, 661.35 Nm ³ Synthetic gasi, 1.0578 matani e crude chlorine inogadzirwa ne co reaction, uye hapana methacrylic acid chigadzirwa mukugadzira maitiro. .
Zvinoenderana nedata rakakosha rakaburitswa neShanghai Yunsheng Chemical Technology Co., Ltd., iyo MMA mutengo weethylene nzira ingangoita 12000 yuan/ton kana ethylene iri 8100 yuan/ton, methanol iri 2140 yuan/tani, gasi rekugadzira riri 1.95 yuan/ cubic meter, uye crude chlorine i600 yuan/ton.Kuenzaniswa nenguva imwechete, mari yepamutemo yeC4 nzira uye ACH nzira yakakwirira.Nokudaro, maererano nemamiriro ezvinhu emusika, ethylene MMA haina kukwikwidzana kwehupfumi kwakajeka.
Nekudaro, kugadzirwa kweMMA ne ethylene nzira inogona kuenderana ne ethylene zviwanikwa.Ethylene inonyanya kubva kune naphtha cracking, coal synthesis, etc. Muchiitiko ichi, kukwikwidzana kweMMA kugadzirwa nenzira ye ethylene kuchanyanya kukanganiswa nemutengo we ethylene raw materials.Kana iyo ethylene raw material yakazvipa yega, inofanirwa kuverengerwa zvichienderana nemutengo wemutengo we ethylene, izvo zvichavandudza zvakanyanya kukwikwidza kwemutengo we ethylene MMA.
Chechitatu, ethylene MMA inodya yakawanda yeklorini, uye mutengo uye hukama hunotsigira hweklorini hucharatidzawo kiyi yekukwikwidza kwemutengo we ethylene MMA.Zvinoenderana nemaitiro ekugadzira eBASF naLucite, ese ari maviri maitiro anoda kushandisa yakawanda chlorine.Kana chlorine ine hukama hwayo hunotsigira, mutengo weklorini haudi kutariswa, izvo zvichanyanya kuvandudza mutengo wemakwikwi ethylene MMA.
Parizvino, ethylene MMA yakwezva kutariswa zvakanyanya nekuda kwekukwikwidza kwemitengo yekugadzira uye yakapfava yekushanda nharaunda yeyuniti.Pamusoro pezvo, izvo zvinodikanwa zvekutsigira zvigadzirwa zvinopindirana neiyo yazvino nzira yekusimudzira yeindasitiri yemakemikari yeChina.Kana bhizinesi richitsigira ethylene, chlorine uye synthesis gasi, ipapo ethylene MMA inogona kunge iri yakanyanya kukwikwidza MMA maitiro ekugadzira parizvino.Parizvino, nzira yekusimudzira yeindasitiri yemakemikari yeChina inonyanya kuzara kutsigira zvivakwa.Pasi pemaitiro aya, iyo ethylene nzira inoenderana ne ethylene MMA inogona kuve yakatarisana neindasitiri.
