Suuqa Shiinaha, geedi socodka wax soo saarka ee MMA wuxuu horumariyey ku dhawaad ​​lix nooc, howlahanna dhammaantood waa ay warshadeen. Si kastaba ha noqotee, xaalada tartanka ee MMA si weyn ayey ugu kala duwan tahay geedi socodka kala duwan.

Waqtigan xaadirka ah, waxaa jira seddex habraac wax soo saarka oo loogu talagalay MMA:

Acetone Cyanohyhrind Habka (Habka ACH): Tani waa mid ka mid ah geedi socodka wax soo saarka ee ugu muhiimsan ee warshadaha, oo leh tikniyoolajiyadda qaangaarka iyo hawlgal fudud.

Habka carbobiska eethylene: Tani waa geeddi-socod wax soo saar cusub oo leh wax soo saarka cusub oo leh wax-ka-tafcayn sare ee falcelinta iyo tayada wax soo saarka.

Habka loo yaqaan 'beboutne-ka' (Qaabka C4): Tani waa geeddi-socod wax soo saar oo ku saleysan geesaha dekeda oksidative of okenene, oo si fudud looga heli karo agab cayriin iyo kharashyo hooseeya.

Iyadoo lagu saleynayo saddexdaas geeddi-socod, waxaa jira seddex geeddi-socod wax soo saar oo la wanaajiyey sida soo socota:

Hagaajinta ACH ee Hagaajinta

Habka aashitada aashitada ee barafka: Nidaamkani wuxuu adeegsadaa barafka aashitada aashitada sida sheyga ceyriinka ah, mana jiraan badin saddex wasakh ah inta lagu gudajiro nidaamka wax soo saarka, taasoo ka dhigaysa bey'ad u fiican.

Basf iyo geedi socodka lucadaha, oo badanaa matalaya magaca shirkada, ayaa maray horumar farsamo oo u gaar ah oo ku saleysan astaamaha shirkaddooda ay ka kala horreeyaan, oo leh faa iido gaar ah iyo faa'iidooyin tartan.

Waqtigan xaadirka ah, lixdan geeddi-socod ee wax soo saarka ayaa dhammaantood gaadhay soosaarka cutubyada iyadoo loo eegayo qiyaasta 10000 tan ama in ka badan Shiinaha. Si kastaba ha noqotee, tartanka u dhexeeya geedi socodyo kaladuwan ayaa si weyn ugu kala duwan arrimo ay ka mid yihiin arrimo ay ka mid yihiin astaamaha iyo kharashyadahooda. Mustaqbalka, hormarinta tikniyoolajiyadda iyo horumarka suuqa, muuqaalka tartan ee geedi socodkan wax soo saarka ayaa laga yaabaa inuu isbedelo.

Isla mar ahaantaana, waxaa muhiim ah in la sheego in bisha Sebtember 2022, waaxda bandhig ee warshadaha ee Methanol 10000 ee methars ee methacylate-ka (MAR) oo ay si madaxbanaan ay u horumarisay machadka injineerinka ee akadeemiyadeed ee Shiinaha ay tahay si guul leh ayaa loo bilaabay oo ku shaqeeyay si nabdoon, iyo badeecaduhu waxay ahaayeen ilaa heer. Qalabkaani waa methanol-ka dunida ee salka ku haysa aashitada aashitada aashitada ee 'Mma warshadaha', oo gaadhay isbadalka wax soo saarka methyllate ee metherlate-ka oo ka mid ah ku tiirsanaanta batroolka ashyaa'da ceyriinka ee salka ku haysa.

Beddelka sabab u ah muuqaalka tartan ee loo tartamayo, sahayda iyo baahida loo baahan yahay ee alaabooyinka MMA ayaa isbedelay, qiimahooduna wuxuu muujinayaa isbadal ciriiri ah. Labadii sano ee la soo dhaafay, qiimaha ugu sarreeya ee suuqa ee MMA ee Shiinaha ayaa gaadhay 14014 yuan / tan, qiimaha ugu hooseeyana waa qiyaastii 10000 yuan / tan. Laga soo bilaabo Agoosto 2023, qiimaha suuqa MMA wuxuu hoos ugu dhacay 11500 yuan / tan. Badeecada ugu weyn ee wax soo saarka hoose waa PMMA, oo muujisay isbeddelada daciifka ah ee qiimaha suuqa labadii sano ee la soo dhaafay, iyadoo qiimaha ugu badnaan 17560 yuan / tan iyo qiimaha ugu yar ee 14625 yuan / tan. Laga soo bilaabo Agoosto 2023, qiimaha guud ee suuqa P /-da ayaa isbeddelay 14600 yuan / tan. Waa in la ogaadaa in sababtu tahay xaqiiqda ah in waxyaabaha soosaarka PMMMA ay caadiyan ka jiraan bartamihii magacyada ugu hooseeya, heerka qiimaha badeecada ay ka hooseyso tan suuqa laga soo dejiyo.

1.Iyadoo aan la tixgalin qeybta Mma ACIDO AIDO AIDAH ACID, habka wax soo saarka eethylene MMA uu lahaa tartanka ugu adag labadii sano ee la soo dhaafay.

Labadii sano ee la soo dhaafay, habka wax soo saarka ee Ethyleneneeneene wuxuu leeyahay tartankii ugu xoogan ee suuqa Shiinaha. Marka loo eego tirakoobka, wax soo saarka wax soo saarka ee Ethylene ee ku saleysan MMA waa kan ugu hooseeya ee tartankeeduna waa kan ugu xoogan. Sanadkii 2020, qiimaha cilmiga maskaxda ee Ethylene ee ku saleysan MMA waxay ahayd 5530 yuan halkii ton, halka Janaayo 2023, celcelis ahaan qiimaha ay ahayd 6088 yuan halkii ton. Taas bedelkeeda, habka 'Basf' waxay leedahay qarashka soosaarka ugu sarreeya, iyadoo qiimaha MMA ah 10765 Yuan halkii ton oo ah 2020 iyo qiimaha celcelis ahaan 11081 yuan halkii-dii ee 110-kii Janaayo 2023.

Markii la qiimeynayo tartanka geedi socodka wax soo saarka ee kaladuwan, waxaan u baahan nahay inaan fiiro gaar ah u yeeshano kala duwanaanshaha ku saabsan isticmaalka unugyada ee agabyada ceeriin ee geedi socodka kala duwan. Tusaale ahaan, isticmaalka shey ceyriin ee habka ethylene-ka waa 0.35 Etherene, 0.84 methanol, iyo 0.38 synthesis gaaska, halka habka '' basfy 'ay muhiimad gaar ah tahay, laakiin isticmaalkeeda' Metherenene 'waa 0.429, Isticmaalka methanol waa 0.387, iyo isticmaalka gaaska synthesis-ka waa 662 mitir cubic. Kala duwanaanshahaasi waxay saameeyaan qiimaha wax soo saarka iyo tartamada hanaanka kala duwan.

Iyada oo ku saleysan qiyaasaha qaaska ah sanadihii la soo dhaafay, darajooyinka Tartanka MMA ee geedi socodka kaladuwan waa: Habka Ethylene-ka> Habka 'C4'> Habka loo yaqaan 'ACH'> Habka ACCE> Habka Lucite> Habka Lucite> Habka Lucite> Habka Lucite> Habka Lucite> Habka Lucite> Habka Lucid> Darajadan waxaa inta badan saameyn ku leh kala duwanaanshaha injineerinka guud ee ka dhex jira geedi socodka kala duwan.

Mustaqbalka, hormarinta tikniyoolajiyadda iyo horumarka suuqa, muuqaalka tartan ee geedi socodka kala duwan ayaa is beddeli kara. Gaar ahaan iyada oo aan la tixgalin aaladda MMA aashitada aashitada, Ethylene MMA ayaa la filayaa inay sii wado sii wadidda faa'iidada ay tahay tartankeeda.

2.Habka aashitada aashitada ee MMA ayaa la filayaa inuu noqdo habka ugu tartamaya tartanka

Machadka geeddi-socodka injineerinka ee akadeemiyada Shiinaha ee cilmiga Shiinaha ayaa si guul leh u horumariyay methanol ee methanol-ka ee salka ku haysa ee salka ku haysa baradka ee Methanol aashitada ee 'MMA' ee 'MMA'. Dhirtu waxay qaadataa methanol iyo aashitada acetic acid sida qalabka ceyriinka ah, iyo hanaanka umulida aldol, hydrogenition, iwm., Iwm. Hawshani waxay leedahay horumar cad, oo aan howsha oo keliya waa gaaban yahay, laakiin sidoo kale alaabta ceyriinka ahi waxay ka yimaadaan dhuxul, oo leh faa'iidooyin muuqda oo muuqda. Intaas waxaa sii dheer, xajijiang zhongyou Puhui tikniyoolajiyadda Puhui Commochog, Ltd. waxay qorsheyneysaa rakibo warshadeed oo baaxad leh oo ah 110000 tan / sanadka, taas oo dhiirigelin doonta casriyeynta iyo horumarinta warshadaha MMA ee Shiinaha. Marka la barbar dhigo geedi socodka soosaarka ee MMOLEUM ee ku saleysan ee MMOLEUM ee ku saleysan Acid Acid Acid Acid Acid Acid ayaa aad u habboon oo dhaqaale ahaan faa'iido leh oo dhaqaale ahaan faa'iido leh, waxaana la filayaa inuu noqdo jiho horumarineed oo muhiim u ah mustaqbalka warshadaha MMA ee mustaqbalka.

3.Waxaa jira kala duwanaansho weyn oo ku saabsan culeyska culeyska saameynta ee howlaha kala duwan

Farqi weyn ayaa ku jira kharashka saameynta culeyska ee geedi socodka wax soo saarka ee MMA, iyo culeyska miisaaniyada ee qodobbada kaladuwan ee ku saabsan kharashaadka ayaa ku kala duwan tikniyoolajiyadda hawsha.

ACH MMA, qiimaha isbeddelada acetone, methanol, iyo acrylonitrile waxay saameyn weyn ku leeyihiin kharashkeeda. Waxaa ka mid ah, isbedelada qiimaha acetone-ka ayaa leh saameynta ugu weyn ee qarashku ku yeesho kharashaadka, iyadoo la gaarayo 26%, halka qiimaha metrylonile iyo acrylonitrile ay saameeyaan 57% iyo 18% kharashyada, siday u kala horreeyaan. Taa bedelkeeda, qiimaha methanol wuxuu ku xisaabtamayaa kaliya 7%. Sidaa darteed, daraasadda silsiladda qiimaha ee Charch ee ACH MMA, fiiro gaar ah ayaa loo baahan yahay in la siiyo isbedelka qiimaha acetone.

Qaabka C4 ee MMA, daahirsanaanta sare ee Isobutenene waa qiimaha ugu weyn ee doorsoomayaasha ah, xisaabaadka ku dhawaad ​​58% qiimaha MMA. Methanol waxay akoonnada ku dhawaad ​​6% qiimaha MMA. Qiimaha isbeddelka Isoboutenene waxay saameyn weyn ku leedahay qiimaha Qaabka C4 ee MMA.

Wixii Ethylenene ah oo ku saleysan MMA, isticmaalka unug ee Ethylene Sytylene ee ka badan 85% qiimaha MMA ee hanaankan, taas oo ah saameynta ugu weyn ee qiimaha ugu weyn. Si kastaba ha noqotee, waa in la ogaadaa in inta badan etlylene inteeda badan loo soo saaro sida qalabka iskiis u soo saaray, iyo degitaanka gudaha inta badan waxay ku saleysan tahay degitaanka qiimaha qiimaha. Sidaa darteed, heerka tartan rasmi ah ee etherlene-ka ah ma noqon karo sida heerka dhabta ah ee tartanka dhabta ah.

Marka la soo koobo, waxaa jira kala duwanaansho weyn oo ku saabsan culeyska miisaaniyada kaladuwan ee sababaha kala duwan ee wax soo saarka ee MMA, iyo falanqaynta loo baahan yahay in lagu sameeyo iyada oo lagu saleynayo tikniyoolajiyadda hawsha gaarka ah.

4.Geedi socodka waxsoosaarka ee MMA noocee ah ayaa mustaqbalkiisa ugu hooseeya?

Xaaladda teknolojiyada ee hadda jirta, heerka tartanka ee MMA ee geedi socodka kala duwan ee mustaqbalka ayaa si aad ah saameyn ugu yeelata isbeddelada qiimaha cayriin ee cayriin. Alaabada ceyriinka ah ee loo adeegsaday dhowr geedi socodyo soosaarka MMA ee ugu waaweyn waxaa ka mid ah mtbe, methanol, acetone, sulfuric acid, iyo ethylne. Alaabooyinkan ayaa la iibsan karaa ama lagu bixin karaa gudaha gaas is-dhexgal ah, xargaha gaaska, ashyaa'da isku-darka ah, ashyaa'da kaaliyaha ah, aashitada hydrogyanic, iwm.

Waxaa ka mid ah, qiimaha Mtbe inta badan wuxuu raacaa isbeddelada isbeddelka ee suuqa saliida ee la safeeyey, qiimaha saliida la safeeyey ayaa si dhaw ula ah qiimaha saliidda cayriin. Out of off of offthert offtht of off ee qiimaha saliidda mustaqbalka, qiimaha MTBE sidoo kale waxaa laga filayaa inuu muujiyo isbeddel kor u dhaaf ah, oo la filayo in isbeddelka kor u kacayo uu ka xoog badan yahay saliida ceyrka. Qiimaha methanol ee suuqa ayaa isbeddelaya sicirka qiimaha dhuxusha, iyo saadka mustaqbalka ayaa la filayaa inuu sii kordhayo si aad ah. Si kastaba ha noqotee, horumarinta qaabka silsiladda warshadaha ayaa horseedi doonta koror ku yimaada qiimayaasha is-isticmaalka ee hoos u dhaca, iyo qiimaha buuqa loo yaqaan 'Metanol methanol' ee methanol ayaa la filayaa inuu sii wado.

Bixinta iyo Baahiga Deegaanka ee suuqa acetone-ka ayaa ka sii daraya, iyo dhismaha mashaariicda cusub iyadoo la adeegsanayo habka 'ACH', iyo qiimaha muddada-dheer ee isbeddelka muddada-dheer ayaa laga yaabaa inay liitaan. Ethyllene waxaa inta badan la bixiyaa gudaha waxayna leedahay tartan qiimo adag.

Sidaa darteed, iyadoo lagu saleynayo xaaladda teknolojiyada hadda jirta iyo isbeddelka isbeddelka ee qiimaha cayriin, ayaa wali jira waxoogaa hubanti ah oo ku saabsan geedi socodka wax soo saarka ee MMA uu lahaan doono qiimaha ugu hooseeya mustaqbalka. Si kastaba ha noqotee, waxaa laga yaabaa in la saadaaliyo in macnaha guud ee saliida iyo qiimaha dhuxusha, qiimaha alaabta ceyriinka sida methanol iyo Mtbe ay sidoo kale saameyn weyn ku yeelan karaan heerka tartan ee MMA hanaanka kala duwan ee MMA. Si loo ilaaliyo tartanka, soo-saareyaashu waxay u baahan karaan inay raadiyaan kanaallo dhaqaale oo cayriin oo hufan oo hufan, iyagoo xoojinaya kobcinta iyo hal-abuurka geedi socodka wax soo saarka si loo yareeyo waxyaabaha wax soo saarka loona wanaajinayo tayada wax soo saarka iyo hagaajinta tayada wax soo saarka.

Tartanka Tartanka ee habraacyada Mma ee kala duwan ee Shiinaha mustaqbalka ayaa la filayaa inay sii wadaan inay u xoog badnaato nidaamka etrylen, oo ay ku xigto habka ACH ee taageeraya qaybta acrylonile, ka dibna nidaamka C4. Si kastaba ha noqotee, waa in la ogaadaa in mustaqbalka shirkadaha ay ku koban doonaan moodal silsilado warshadeed, kaasoo noqon doona habka ugu tartamida ugu tartanka ah ee ah badeecadaha-qiime jaban iyo hoos-u-dhigista hoos udhaca PMMA ama waxyaabaha kale ee kiimikada ah.

Sababta habka loo filayo in habka ethellene ay tahay inuu xoog yeesho waxaa sabab u ah helitaanka adag ee ethylene, kaasoo xisaabaya tiro aad u sarreeya oo ah qiimaha soosaarka ee MMA. Si kastaba ha noqotee, waa in la tilmaamaa in dadka ethylene in gudaha lagu bixiyo gudaha, heerka xirfadeed ee tartanku uusan u badnaan karin sida heerka dhabta ah ee tartanka dhabta ah.

Qaabka 'ACH' wuxuu leeyahay tartan adag markii uu ku dhexjiro unug acrylonile ah, sababta oo ah achice brobutenene-ka ugu weyn ee maaddada ugu weyn ee qarashka MMUTENE, halka habka 'Exclutlen', halka habka loo yaqaan '' ISMutlutne ', sidaasna loo yareeyo kharashaadka .

Tarjumanaanta habraaca ah sida habka C4 uu yahay mid daciif ah, badiyaa sababtuna tahay isbeddelada qiimaha weyn ee ashyaa'da ceyriinka ah isbaraaca iyo acrylonitrile iyo acrylonitrile iyo acrylonitrile iyo acrylonitrile iyo acrylonitrile-ka qiimaha soosaarka ee MMAUTE.

Guud ahaan, habka ugu tartamaya ee silsiladda warshadaha ee ugu tartamaya MMA mustaqbalka ayaa noqon doona shirkado si loo horumariyo moodal silsilado warshadeed, oo ah wax-ka-dhigga-hooseysa iyo hoos u dhigista hoos udhaca PMMMA ama alaabada kale ee kiimikada. Tani kaliya ma yarayn karto qarashka wax soo saarka oo keliya kor u qaadida kartida wax soo saarka, laakiin sidoo kale si fiican ayey u buuxisaa baahida suuqa.
