Ku ya 1 Nyakanga 2022, umuhango wo gutangira icyiciro cya mbere cya toni 300.000methyl methacrylate. CAS na Zhongyuan Dahua.Iki nicyo gihingwa cya mbere cyitwa Ethylene MMA cyasohotse mubushinwa.Niba ibikoresho bishyizwe mubikorwa neza, bizagera ku ntera mu musaruro wa Ethylene MMA mu Bushinwa, bigira ingaruka zikomeye ku nganda za MMA.
Igice cya kabiri cya MMA yuburyo bwa Ethylene mubushinwa gishobora gutangazwa muri Shandong.Biteganijwe ko byambere bizashyirwa mubikorwa hafi 2024, kandi ubu biri mubyiciro byambere.Niba iki gice ari ukuri, kizaba igice cya kabiri cya MMA cyibikorwa bya Ethylene mubushinwa, bifite akamaro kanini mugutandukanya ibikorwa bya MMA mubushinwa no guteza imbere inganda z’imiti mu Bushinwa.
Dukurikije amakuru afatika, hari inzira zikurikira za MMA mubushinwa: inzira ya C4, inzira ya ACH, kunoza imikorere ya ACH, inzira ya BASF etylene na Lucite etylene.Kwisi yose, ubwo buryo bwo kubyaza umusaruro bufite inganda.Mu Bushinwa, amategeko ya C4 n’amategeko ya ACH yatejwe imbere mu nganda, mu gihe amategeko ya Ethylene atigeze akora inganda.
Kuki uruganda rukora imiti mu Bushinwa rwagura uruganda rwa Ethylene MMA?Igiciro cyumusaruro wa MMA cyakozwe nuburyo bwa Ethylene burahiganwa?
Ubwa mbere, uruganda rwa Ethylene MMA rwakoze ubusa mubushinwa kandi rufite urwego rwo hejuru rwikoranabuhanga.Nk’uko ubushakashatsi bwabigaragaje, ku isi hari ibice bibiri gusa bya Ethylene MMA ku isi, biherereye mu Burayi no muri Amerika ya Ruguru.Imiterere ya tekiniki ya Ethylene MMA ibice biroroshye.Igipimo cyo gukoresha atome kirenga 64%, kandi umusaruro urenze ubundi bwoko bwibikorwa.BASF na Lucite bakoze ubushakashatsi bwa tekiniki no guteza imbere ibikoresho bya MMA kubikorwa bya Ethylene hakiri kare, kandi bigera ku nganda.
Igice cya MMA cyibikorwa bya Ethylene ntabwo kigira uruhare mubikoresho fatizo bya acide, nabyo biganisha ku kwangirika kwinshi kwibikoresho, gutunganya umusaruro ugereranije n’ibidukikije, hamwe nigihe kinini cyo gukora muri rusange.Muri iki kibazo, igiciro cyo guta agaciro kwa MMA murwego rwa Ethylene mugihe cyo gukora kiri munsi yizindi nzira.
Ibikoresho bya Ethylene MMA nabyo bifite ibibi.Ubwa mbere, ibikoresho byunganira ibihingwa bya Ethylene birasabwa, aho Ethylene ikorwa cyane nibihingwa byahujwe, bityo rero birasabwa gushyigikira iterambere ryimishinga ihuriweho.Niba Ethylene iguzwe, ubukungu burakennye.Icya kabiri, hano hari ibice bibiri gusa byibikoresho bya Ethylene MMA kwisi.Imishinga y'Ubushinwa irimo kubakwa ikoresha ikoranabuhanga rya Academy ya siyanse y'Ubushinwa, kandi izindi nganda ntizishobora kubona byoroshye kandi neza ikoranabuhanga.Icya gatatu, ibikoresho bya MMA byuburyo bwa Ethylene bifite inzira ndende, ishoramari rinini, umubare munini wa chlorine urimo amazi y’amazi bizabyara umusaruro, kandi amafaranga yo gutunganya imyanda itatu ni menshi.
Icya kabiri, ibiciro byo guhatanira ibiciro bya MMA ahanini biva muri etylene ishigikira, mugihe Ethylene yo hanze idafite inyungu zo guhatanira.Nk’uko iperereza ryabigaragaje, ishami rya MMA ryuburyo bwa Ethylene ni toni 0.4294 za Ethylene, toni 0.387 za methanol, 661.35 Nm gas Gazi ya sintetike, toni 1.0578 ya chlorine ya chorine ikorwa na co reaction, kandi nta bicuruzwa bya methacrilike biri mubikorwa byo gukora. .
Dukurikije amakuru ajyanye n’amakuru yashyizwe ahagaragara na Shanghai Yunsheng Chemical Technology Co., Ltd., ikiguzi cya MMA cy’uburyo bwa Ethylene kigera kuri 12000 Yuan / toni iyo Ethylene ari 8100 / toni, methanol ni 2140 Yuan / toni, gaze ya sintetike ni 1.95 Yuan / metero kibe, na chlorine itubutse ni 600 yuan / toni.Ugereranije nigihe kimwe, ibiciro byemewe nuburyo bwa C4 nuburyo bwa ACH ni byinshi.Kubwibyo, ukurikije uko isoko ryifashe ubu, Ethylene MMA ntabwo ifite ubushobozi bwo guhangana nubukungu.
Nyamara, umusaruro wa MMA muburyo bwa Ethylene birashoboka ko uhura numutungo wa Ethylene.Ethylene ahanini ituruka kumeneka ya naphtha, synthesis yamakara, nibindi. Muri iki gihe, guhatanira umusaruro wa MMA hakoreshejwe uburyo bwa Ethylene bizaterwa ahanini nigiciro cyibikoresho fatizo bya Ethylene.Niba ibikoresho fatizo bya Ethylene ubwabyo bitangwa, bigomba kubarwa hashingiwe ku giciro cyigiciro cya Ethylene, bizamura cyane ibiciro byo guhangana na Ethylene MMA.
Icya gatatu, Ethylene MMA ikoresha chlorine nyinshi, kandi igiciro nubusabane bushigikira chlorine nabyo bizagena urufunguzo rwo guhangana nigiciro cya Ethylene MMA.Ukurikije uburyo bwo gukora bwa BASF na Lucite, izi nzira zombi zigomba kurya chlorine nyinshi.Niba chlorine ifitanye isano nayo, ikiguzi cya chlorine ntigikenewe gusuzumwa, bizamura cyane ibiciro byo guhangana na Ethylene MMA.
Kugeza ubu, Ethylene MMA yakunze kwitabwaho cyane cyane kubera guhangana n’ibiciro by’umusaruro hamwe n’ibidukikije byoroheje bikora.Byongeye kandi, ibisabwa mu gushyigikira ibikoresho fatizo nabyo bihuye nuburyo bugezweho bwiterambere ry’inganda z’imiti mu Bushinwa.Niba uruganda rushyigikiye gaze ya Ethylene, chlorine na synthesis, noneho Ethylene MMA irashobora kuba igiciro cyinshi cyo guhatanira umusaruro MMA muri iki gihe.Kugeza ubu, uburyo bw’iterambere ry’inganda z’imiti mu Bushinwa ahanini ni ibikoresho byunganira.Muri ubu buryo, uburyo bwa Ethylene buhuye na Ethylene MMA bushobora kuba intego yibikorwa byinganda.
