Ukulungisa Amasu Okusetshenziswa Kwezinto Ezingavuthiwe Kwabakhiqizi Be-Calcined Petroleum Coke Phakathi Kokuqiniswa Kokunikezwa Kwe-Sulfur Ephansi
Ngokuphikisana nesizinda se-coke kaphethiloli ephansi ye-sulfur eyandayo (okuqukethwe kwe-sulfur <1%, ikakhulukazi i-coke ye-sulfur ephansi kakhulu <0.5%) kanye nokuncintisana okwandayo kwesidingo esivela ezintweni ze-anode zebhethri le-lithium kanye nama-anode abhakwe kusengaphambili aphezulu, izitshalo ze-calcination kumele zishintshe amasu azo ezinto zokusetshenziswa kusuka ekufuneni okunomqondo owodwa kwe-sulfur ephansi ziye endleleni ehlelekile yokuhambisana kwemithombo eminingi, ukusetshenziswa kwe-cascading, ukufaka esikhundleni sobuchwepheshe, kanye nokuvikela ubungozi. Ukucabanga okuyinhloko kungafingqwa ngalezi zindlela ezilandelayo:
I. Ukulungiswa Kwesakhiwo Sezinto Ezingavuthiwe: Kusukela “Ku-Sonke I-Sulfur Ephansi” Kuya “Ekuhlanganisweni Kwesayensi Kwe-Sulfur Ephansi + I-Sulfur Ephakathi”
Iphuzu elibuhlungu kakhulu nge-low-sulfur coke ukuthi iyabiza futhi ayitholakali kalula. Esikhathini esidlule, izitshalo ze-calcination zazivame ukusebenzisa kakhulu i-low-sulfur coke ukuqinisekisa ukuhambisana kwe-sulfur yomkhiqizo. Kodwa-ke, endaweni yokutholakala okuncane kanye namanani aphezulu kakhulu (ngo-2025, intengo emaphakathi ye-#1 low-sulfur coke ibone ukwanda konyaka nonyaka okungaphezu kuka-57% ngesikhathi esisodwa), le ndlela ayisasebenzi.
Isu elisebenzayo ukusungula uhlelo "lokuxuba i-sulfur olusezingeni eliphezulu". Ama-anode abhakiwe kusengaphambili kanye nama-electrode avamile e-graphite anokubekezelela okuthile kokuqukethwe kwe-sulfur. I-sulfur coke ephakathi nendawo ephansi ingaxutshwa ne-sulfur coke ephansi ngezilinganiso ezithile (isb., i-sulfur ephansi: i-medium-sulfur = 4:6 noma 3:7) ukuze kuncishiswe kakhulu izindleko zezinto zokusetshenziswa ngenkathi kuhlangatshezwana nezidingo ze-sulfur yomkhiqizo ongezansi. Isihluthulelo ukwakha i-database yayo yonke inqwaba yezinto zokusetshenziswa ezihlanganisa okuqukethwe kwe-sulfur, i-volatile matter, i-true density, kanye nezinto zokulandelela (V, Ni, Fe, njll.), bese usebenzisa amamodeli okuqamba ukubala ngokunembile izilinganiso zokuxuba ukuqinisekisa izakhiwo ezizinzile ze-physicochemical ze-calcined coke.
Ezitshalweni ze-calcination, lokhu kusho ukuthi uhlangothi lokuthengwa kumele luqinisekise ngasikhathi sinye imithombo ye-coke ephakathi nesibabule (i-coke ephakathi nesibabule evela ezindaweni zokuhlanza ezizimele zasekhaya ihlanganisa cishe u-38% wokunikezwa okuphelele futhi iningi kakhulu), kunokugxila konke ukucindezela kokuthengwa kwe-coke ephakathi nesibabule.
II. Ukuhlukahluka Kweziteshi Zokungenisa: Valela Imithombo Ezinzile Futhi Usakaze Ingozi Yezwe
I-coke yasekhaya ene-sulfur ephansi ikhiqiza cishe u-14% kuphela womkhiqizo we-coke kaphethiloli (okuqukethwe kwe-sulfur <0.5% kuqukethe cishe u-4%), kuyilapho ama-anode ebhethri le-lithium esevele edla cishe u-29% wesidingo se-coke ene-sulfur ephansi futhi asakhula ngokushesha. Igebe lokuphakelwa kwasekhaya alikwazi ukuvalwa esikhathini esifushane. Ngakho-ke, ukungenisa i-coke ene-sulfur ephansi kusalokhu kuyisengezo esibalulekile, kodwa izitshalo azikwazi ukuthembela emthonjeni owodwa.
Izenzo ezithile zifaka:
- Ukuthola izimpahla emazweni amaningi: Ngaphandle kwemithombo yendabuko yaseMpumalanga Ephakathi kanye neNingizimu-mpumalanga ye-Asia, gxila emithonjeni ye-coke engeyona eyendabuko ene-sulfur coke efana neRussia ne-Azerbaijan. Sayina izivumelwano zokuthatha izimpahla zesikhathi esimaphakathi kuya kweside (iminyaka engu-1-3) ngendlela "yentengo elinganiselwe + ukulungiswa okuntantayo" ukuze uvale intengo ephansi.
- Yandisa ukungeniswa kwe-coke ene-sulfur ephezulu njengezinye izindlela: I-coke ene-sulfur ephezulu inokusetshenziswa okulinganiselwe kuma-anode abhakiwe ngaphambilini asekhaya ngenxa yokukhathazeka ngokukhishwa kwe-SO₂, kodwa isenezimakethe zemikhiqizo yekhabhoni ezingazweli kakhulu kwi-sulfur, i-silicon carbide, i-calcium carbide, njll. I-Southeast Asia kanye ne-Middle East high-sulfur coke inikeza izinzuzo zentengo ezicacile. Izitshalo ze-calcination zingasungula imigqa ye-calcination ye-coke ene-sulfur ephezulu ehlose le mikhiqizo engezansi.
- Sebenzisa amathuluzi esikhathi esizayo nezinketho: Vimbela u-30%–50% wamanani okuthengwa kwempahla engenayo, bese usebenzisa ukuvikela ukushintshaniswa kwemali yangaphandle ukuze unciphise ingozi ephindwe kabili yokuguquguquka kwesilinganiso sokushintshaniswa kwemali kuhlanganiswe nokuguquguquka kwentengo.
III. Ukufakwa Kobuchwepheshe Nokuthuthukiswa Kwefomula: Nciphisa Ukuthembela Ku-Low-Sulfur Coke Emthonjeni
Lena indlela enenani elikhulu kakhulu lesikhathi eside. Ingqikithi yokuntuleka kwe-coke ene-sulfur ephansi ukushintsha kwesakhiwo sesidingo esingezansi - ama-anode ebhethri le-lithium kanye nama-electrode e-graphite aphezulu akhula ngokushesha kakhulu kunokunikezwa. Uma izitshalo ze-calcination zixazulula inkinga kuphela ohlangothini lokuthengwa, zizohlala zisabela. Kumelwe futhi zenze intuthuko ohlangothini lobuchwepheshe.
Izindlela eziningana eziqinisekisiwe noma ezilandelwayo ngenkuthalo:
- Ukuhlanganisa izinto ezisizayo ukuze kuncishiswe ukusetshenziswa kwe-coke ene-sulfur ephansi: Ukwengeza i-graphite ephinde yasetshenziswa, i-carbon fiber, nezinye izinto ezisizayo ekwakhiweni kwezinto ze-anode kanye nemikhiqizo yekhabhoni ephezulu kunganciphisa ukusetshenziswa kwe-coke ene-sulfur ephansi ngo-10%–15%. Ngesikhathi esifanayo, izinqubo zokubhaka kanye ne-graphitization ezithuthukisiwe zinganciphisa ukusetshenziswa kwe-coke ene-petroleum ngeyunithi ngayinye ngo-8%–10%.
- Ukushintshaniswa okuyingxenye nge-needle coke esuselwe kumalahle: I-needle coke esuselwe kumalahle ibiza cishe u-20% ngaphansi kune-petroleum coke, futhi isabelo sayo sokusetshenziswa ezintweni ze-anode sikhuphuke sisuka ku-15% saya ku-28%. Kweminye imikhiqizo esezingeni eliphezulu, ukusetshenziswa ngokubambisana kwe-needle coke esuselwe kumalahle kanye ne-low-sulfur coke ezimbonini sekuvele kungenzeka. Izitshalo zokugaya i-calcination zingakha amandla okugaya i-needle coke ngendlela esebenzayo.
- I-graphite yemvelo njengenye indlela: I-graphite yemvelo ene-surface coating (isb., i-nano-silicon carbide coating) ifinyelele impilo yomjikelezo edlula imijikelezo engu-2,000 ngentengo ephansi ngo-30% kune-graphite yokwenziwa, futhi isabelo sayo semakethe sikhule sisuka ku-15% saya ku-25%. Lokhu kudala ukuncintisana okuqondile namabhizinisi ezinto ze-anode athembele ku-coke ene-sulfur ephansi, okuphoqa izitshalo ze-calcination ukuthi zicabangele ngokungathi sína ukufaka esikhundleni sezinto zokusetshenziswa.
- Gada izinto zokusetshenziswa ezivelayo njenge-bio-coke: Nakuba zisaqinisekiswa ngezinga lokuhlola, i-bio-coke ibonise amandla okufaka esikhundleni kweminye imikhiqizo yekhabhoni futhi kufanelekile ukuqhubeka nokulandelela ubuchwepheshe ngezitshalo ze-calcination.
IV. Ukuthuthukiswa Kokusebenza Kahle Kokukhiqiza: Sebenzisa Inzuzo Yenqubo Ukunciphisa Ukwenyuka Kwentengo Yezinto Eziluhlaza
Ukwenyuka kwentengo yezinto ezingavuthiwe kuyizinto zangaphandle, kodwa izinga lokukhiqiza, ukusetshenziswa kwamandla, kanye nezinga lokungcola kwe-coke ene-calcined kungaphansi kolawulo lwesitshalo.
- Thuthukisa izinga lokukhiqiza i-coke ene-calcium: Lungiselela amapharamitha enqubo ye-calcination (izinga lokushisa le-calcination, isikhathi sokuhlala, ukusatshalaliswa komoya) ukuze wandise izinga lokukhiqiza ngamaphuzu angu-1-2 amaphesenti. Lapho amanani eyunithi yezinto zokusetshenziswa enyuka ngama-yuan angamakhulu amaningana ngethani, lokhu kuthuthukiswa kwesivuno esingu-1%-2% kufana nokunciphisa ngqo izindleko zezinto zokusetshenziswa ngeyunithi ngayinye.
- Ukubuyiswa kokushisa okulahlwayo kanye nokuphathwa kwamandla: Ukwethula izinhlelo zokubuyiswa kokushisa okulahlwayo ukuze kuncishiswe ukusetshenziswa kwamandla ngeyunithi ngayinye, futhi kusetshenziswe ugesi ongekho ezingeni eliphezulu kanye nogesi oluhlaza ukuze kuncishiswe izindleko zamandla okukhiqiza.
- Ukuphathwa kwempahla yedijithali: Yakha uhlelo lokuqapha amanani ezinto zokusetshenziswa ukuze ulandelele amanani aqondile nawesikhathi esizayo ngesikhathi sangempela futhi ulungise isikhathi sokuthenga ngendlela eguquguqukayo. Cindezela isitoko sokuphepha kusukela ezinyangeni ezi-3 zendabuko kuya ezinyangeni ezingu-1.5-2, unciphise ukubopha kwenhloko-dolobha kanye nengozi yokwehla kwentengo.
V. Ukubambisana Kwe-Supply Chain: Ukuhlangana Ne-Upstream Ne-Downstream Ukuze Uhlanganyele Ingozi
Esimweni sokuntuleka kwe-coke ene-sulfur ephansi, imodeli yokuthengwa kwe-solo isiphelelwe yisikhathi.
- Sayina izivumelwano zamanani ezixhumene namakhasimende angaphansi komfula: Xoxa ngezindlela zokuxhumanisa "intengo ye-coke - intengo yomkhiqizo" namabhizinisi e-anode abhakiwe kusengaphambili kanye nabakhiqizi bezinto ze-anode. Lapho amanani e-coke kaphethiloli enyuka, amanani omkhiqizo alungiswa ngokulinganayo, kudlule ingcindezi yezindleko ngokushelela phansi komfula.
- Sayina izinkontileka zesikhathi eside nezindawo zokucwenga ukuze zigcine umthamo wazo: Qinisekisa ngaphezu kwama-50% okuthengwa kwe-coke ephansi ye-sulfur minyaka yonke ngezinkontileka zesikhathi eside ezinemigomo yomkhawulo wentengo, ugweme ukuqhutshwa ukuguquguquka kwemakethe yesikhashana.
- Bamba iqhaza ekuxhumaniseni imboni: Khuthaza izinhlangano zemboni ukuthi zihlanganyele ekwenzeni ngcono inqubomgomo yentela yokungenisa ukuze kuncishiswe izindleko zokungenisa i-coke ene-sulfur ephezulu, kwandiswe ngokungaqondile inqwaba yezinto zokusetshenziswa ezingasetshenziswa.
Umugqa Ophansi
Ukuntuleka kwe-coke ene-sulfur ephansi akuyona ukuguquguquka kwesikhathi esifushane kodwa ukuphikisana kwesakhiwo sesikhathi esiphakathi kuya kweside (i-coke yasekhaya ene-sulfur ephansi ikhiqiza u-14% kuphela womkhiqizo ophelele, kuyilapho isidingo se-anode yebhethri le-lithium sikhula ngaphezu kuka-10% ngonyaka). Izitshalo zokugaya i-calcination kumele zishintshe isu lazo lezinto zokusetshenziswa kusukela "ekufuneni i-coke ene-sulfur ephansi" ziye endleleni enezinhlangothi ezinhlanu "yokulawula ukuxuba, ukuhlukanisa ukungenisa, ukusunduza ukushintshwa, ukuthuthukisa ukusebenza kahle, kanye nokubopha amaketanga okuphakelwa." Noma ngubani oqeda le nhlanganisela kuqala uzobamba isinyathelo emjikelezweni olandelayo wezinto zokusetshenziswa.
