Npaj thee tar: tech thiab eco tiam? 

Koj hnov ​​cov thee tar npaj thiab feem ntau cov neeg nyob sab nraud tseem pom qee qhov qub tsev kawm ntawv, grimy byproduct lag luam. Qhov ntawd yog thawj qhov kev xav tsis zoo. Nws tsis yog hais txog kev sau dab tsi tawm ntawm lub qhov cub coke ntxiv lawm. Qhov kev npaj yog qhov kev ua si tiag tiag tam sim no - nws yog hais txog kev txiav cov khoom damn los ntawm kev mus, tweaking lub distillation nkhaus thiab muaj pes tsawg leeg kom haum rau cov kev xav tau tshwj xeeb hauv qab, tsis yog muag cov khoom lag luam loj xwb. Lub siab tsis yog technical xwb; nws yog qhov no tas li thawb-rub ntawm qhov tau txais qhov kev ua tau zoo specs rau tej yam xws li ultra-high-power electrodes thiab tsis tau hammered ntawm ib puag ncig tus nqi. Nws yog ib qho kev sib npaug uas tau hloov kho tag nrho cov khoom siv.

Qhov Kev Npaj tsis yog ib daim ntawv lo xwb

Thaum peb tham txog Npaj Cov Tar Niaj hnub no, peb tab tom tham txog cov khoom siv tshwj xeeb. Ib xyoo caum dhau los, ib daim ntawv cog lus tsuas yog hais txog viscosity thiab ntom. Tam sim no, nws yog hais txog QI (Quinoline Insoluble) cov ntsiab lus, beta-resin qhov tseem ceeb, thiab lub qhov rais softening point. Qhov sib txawv ntawm cov tar haum rau koob coke ntau lawm piv rau ib qho rau cov pa roj carbon dub yog loj heev, thiab nws pib nrog yuav ua li cas koj lis cov crude tar los ntawm coke cub roj. Yog tias koj tsis tswj hwm qhov kev sib xyaw ua ke thiab kev sib sau ua ke kom zoo, koj kaw rau hauv lub siab QI uas yog npau suav phem los daws tom qab rau kev siv high-end. Kuv tau pom cov nroj tsuag uas lawv nyuam qhuav khiav txhua yam kub kom cov kab ntshiab, tab sis qhov ntawd ua rau muaj teeb meem rau txhua tus neeg siv khoom hauv kab uas xav tau cov khoom siv qis QI rau hwm graphite.

Muaj ib qho kev tsis txaus ntseeg ntawm no uas tau ploj lawm. Kev hloov mus rau hluav taws xob arc rauv steelmaking tau tsav kev thov rau UHP (Ultra High Power) graphite electrodes, uas nyob rau hauv lem xav tau koob zoo coke. Qhov tseem ceeb precursor rau ntawd coke? Ib hom tshwj xeeb ntawm Npaj Cov Tar nrog ib tug tshwj xeeb aromatic qauv thiab impurity profile. Nws tsis txaus kom muaj tar; koj xav tau txoj cai tar. Qhov no tau yuam cov neeg tsim khoom sib koom ua ke rov qab, lossis tsawg kawg ua haujlwm ntau dua nrog cov nroj tsuag coking. Nws tsis yog ib qho yooj yim yuav-muag kev sib raug zoo. Qee qhov sib xyaw ua ke ntau dua, zoo li Hebei Yaofa carbon Co., Ltd., siv lawv cov kev tsim khoom mus sij hawm ntev los tswj cov saw no. Los ntawm kev paub tob ntawm cov ntaub ntawv carbon thoob plaws electrodes thiab additives, lawv tuaj yeem qhia cov yam ntxwv tar xav tau los ntawm qhov chaw, uas yog qhov zoo dua. Koj tuaj yeem pom txoj hauv kev no cuam tshuam hauv lawv cov ntaub ntawv ntawm https://www.yafatansu.com - nws tsis yog tsuas yog muag tar lossis electrodes, tab sis nkag siab cov khoom ntws ntawm ib qho mus rau lwm qhov.

Peb sim ib qhov project ib zaug, nrhiav cov tar generic los ntawm ntau cov cokers me me los muab rau kev npaj sib tov. Nws yog ib lub tswv yim txuag nqi. Ua tsis taus pa. Qhov tsis sib xws ntawm cov khoom siv tsis sib xws - sib txawv ntawm cov ntsiab lus ammonia, dej, feem ntau - ua rau cov khoom ruaj khov, spec-npaj khoom tsis yooj yim sua. Lub chaw sib xyaw ua ke tau dhau los ua npau suav phem tshuaj lom neeg, thiab qhov tshwm sim ntawm coke los ntawm nws yog qhov tsis paub tseeb. Qhov kev ua haujlwm ntawm tes tsis ua haujlwm tau tsav tsheb mus rau hauv tsev: qhov sib xws pib ntawm thawj lub sijhawm ntawm kev sau. Koj tsis tuaj yeem kho qhov tsis zoo tar los ntawm kev npaj ua ntej; koj tsuas tuaj yeem txo qee qhov teeb meem ntawm tus nqi siab.

Lub Tech Leaps tsis yog qhov chaw koj xav tau

Feem ntau R & D headlines mus rau flashy carbon daim ntaub ntawv, tab sis qhov tiag, gritty nce mus rau hauv daim yas thee tech tau nyob rau hauv kev sib cais thiab purification. Advanced fractional distillation nrog meej reflux tswj yog tam sim no lub rooj ceg txheem ntseeg. Cov khoom nthuav yog nyob rau hauv cov kuab tshuaj extraction cov tswv yim los rub tawm tej yam khoom muaj nqis xws li carbazole los yog anthracene roj ua ntej lub ntsiab suab ntau lawm, thiab nyob rau hauv de-ashing technologies. Cov centrifuges tau zoo dua, tab sis rau cov khoom siv hluav taws xob tsawg uas xav tau rau lithium-ion roj teeb anode precursors, tshuaj lom neeg lossis thermal kho cov kauj ruam tau raug bolted rau. Nws ntxiv capex, paub meej.

Tom qab ntawd muaj cov ntaub ntawv sab. Cov txheej txheem tswj tau txav los ntawm PLCs yooj yim mus rau cov tshuab uas siv lub sijhawm tiag tiag viscosity thiab dielectric qhov ntsuas tsis tu ncua los kho cov kab ke. Nws suab me me, tab sis ntaus lub qhov muag muag ntawm 108 ° C ± 2 ° C tsis tu ncua, batch tom qab batch, yog qhov tso cai rau cov chaw tsim khoom graphite electrode khiav lawv lub cub tawg zoo. Ib qho kev hloov pauv ntawm 5 degrees tuaj yeem cuam tshuam nrog lub voj voog ci thiab qhov kawg electrode ntom. Yog li cov thev naus laus zis feem ntau yog qhov tsis zoo nkauj, cov txheej txheem nce ntxiv hardening. Nws tsis yog hais txog kev tsim khoom, nws yog hais txog qhov tsis sib xws, uas nyuaj dua li nws suab thaum koj cov khoom noj khoom haus yog qhov sib txawv.

Ib qho teeb meem tshwj xeeb uas peb tau ua nrog yog kev tswj hwm naphthalene hauv cov khoom sib dua. Hauv qee qhov kev lag luam, kev rov qab los thiab muag naphthalene tau txais txiaj ntsig. Hauv lwm tus, nws yog tus nqi. Cov qauv thev naus laus zis ntawm no yog qhov yooj yim: tsim cov tsheb ciav hlau pib distillation kom rov qab tau qhov ntse naphthalene txiav los yog cia nws nyob hauv cov roj feem rau kev ua haujlwm qis, tag nrho raws li kev lag luam hauv lub sijhawm. Nws yuav tsum tau ib tug complex kem tsim thiab ib tug mindset hloov los ntawm kev khiav ib tug taag txheej txheem rau khiav ib tug adaptive ib. Tsis yog txhua cov nroj tsuag laus tuaj yeem ua qhov no, uas tsim kev sib faib hauv kev ua lag luam.

Eco-Pressure yog Reshaping daim ntawv qhia

Cia peb ua blunt: cov lus piav qhia ib puag ncig ib puag ncig thee tar yog qhov nyuaj. Qhov sib txawv tsis yog hais txog kev ntxiv cov tshuaj txhuam hniav lossis cov nroj tsuag dej khib nyiab-tab sis qhov ntawd yog qhov chaw loj heev. Nws yog hais txog tag nrho lub neej voj voog los ntawm kev tshuaj xyuas. VOCs (volatile organic compounds) los ntawm cov tso tsheb hlau luam, PAHs (polycyclic aromatic hydrocarbons) nyob rau hauv chaw ua hauj lwm huab cua, thiab qhov kawg txoj hmoo ntawm lub suab residue yog tag nrho cov kev cai flashpoints. Hauv Tebchaws Europe thiab North America, qhov no tau ua rau kev cog qoob loo lossis kev nqis peev loj heev. Qhov sib txawv tau, nyob rau hauv ib txoj kev, thaj chaw hloov qee qhov kev tsim khoom ntawm qhov tseem ceeb Cov Khoom Siv Carbon rau cov cheeb tsam nrog kev sib koom ua ke, cov chaw niaj hnub uas tau tsim los yog rov kho dua nrog cov kev tswj hwm hauv siab txij thaum pib.

Qhov no tsim ib tug paradox. Kev tswj hwm ib puag ncig nruj me ntsis ua rau cov khoom lag luam kim dua, tab sis lawv kuj muaj peev xwm tsim tau tus nqi rau cov zaub ntsuab lossis ntau dua. Npaj Cov Tar. Qee cov neeg yuav khoom electrode tam sim no tau thov rau cov ntaub ntawv ntawm ib puag ncig hneev taw ntawm cov hlua khi uas lawv siv. Nws tseem tsis tau yog qhov kev thov tseem ceeb, tab sis nws nyob ntawm ntug. Qhov no yog qhov chaw tsim khoom nrog nplai thiab cov txheej txheem niaj hnub tuaj yeem tig tus nqi ua raws li kev ua lag luam kom zoo dua. Ib lub tuam txhab zoo li Hebei Yaofa Carbon, ua cov chaw tsim khoom loj nrog ntau xyoo hauv kev ua si, yuav ntsib cov kev ntxhov siab no. Lawv lub peev xwm los nqis peev rau hauv lub voj kaw kaw, kev ntes cov fume siab, thiab kev kho cov khib nyiab tsis yog kev coj ua zoo xwb; nws tau dhau los ua daim ntawv tso cai ua haujlwm thiab muaj peev xwm sib txawv rau cov neeg siv khoom uas lawv tus kheej nyob rau hauv ESG (Environmental, Social, thiab Kev Tswj Xyuas) cov neeg ua lag luam siab.

Kuv nco qab txog qhov project retrofit rau ib chav tsev tar distillation qhov twg tus nqi loj tshaj tus tsav tsheb tsis yog cov kab tshiab lossis cov khoom siv hluav taws xob hloov hluav taws xob - nws yog lub vapor rov qab system thiab cov thermal oxidizer rau cov roj tawm kom tau raws li cov cai tshiab huab cua. Nws muab ob npaug rau qhov projected capex. Cov ntaub ntawv lag luam tsuas yog ua haujlwm vim tias peb tuaj yeem ua kom muaj txiaj ntsig zoo thiab ua haujlwm zoo rau kev ua lag luam high-end electrode. Yog tsis muaj lub qhov hluav taws xob zoo li ntawd, cov nroj tsuag yuav raug tso tseg. Yog li cov qauv eco ncaj qha yuam kev hloov kho thev naus laus zis, tab sis tsuas yog qhov twg kev lag luam ntawm cov khoom muaj txiaj ntsig kawg tuaj yeem txhawb nqa nws.

Kev ua lag luam yog Fragmenting, tsis ploj

Ib qho kev pom sab nraud yog tias thee tar yog kev lag luam hnub poob. Qhov ntawd tsis yog lawm. Nws yog fragmenting. Cov khoom siv dav dav, cov khoom siv qis rau cov ntaub ntawv yooj yim los yog roj yog qhov tseeb nyob rau hauv siab thiab ntsws. Tab sis lub high-spec, precisely engineered Npaj Cov Tar rau cov khoom siv qib siab carbon yog loj hlob. Cov neeg tsav tsheb xav tau yog cov hluav taws xob megatrend: EAF steelmaking (graphite electrodes) thiab lithium-ion roj teeb (anode koob coke). Ob leeg xav tau cov pa roj carbon zoo, uas xav tau cov khoom ua ntej.

Qhov kev sib cais no txhais tau hais tias cov neeg muag khoom yuav tsum xaiv txoj kab. Koj puas yog tus tswv lag luam uas tsis tshua muaj nqi, lossis tus kws tsim tshuaj tshwj xeeb? Qhov nruab nrab hauv av tau nyem. Txoj kev tshwj xeeb yuav tsum muaj kev pabcuam sib sib zog nqus. Nws tsis yog tsuas yog xa lub tanker; Nws yog hais txog kev ua haujlwm nrog tus neeg siv khoom R & D txog seb koj lub suab coj li cas hauv lawv cov qauv tsim hluav taws xob tshiab lossis lawv cov qauv tshiab anode. Qhov no yog qhov kev paub tseem ceeb. Ib tus neeg muag khoom uas tsuas yog ua tar yuav tsis nkag siab nws tus cwj pwm hauv tus neeg siv khoom lub voj voog. Ib tug vertically integrated carbon producer ua. Qhov ntawd yog tus nqi implicit hauv lub tuam txhab profile zoo li Hebei Yaofa's - lawv 20+ xyoo tsim cov pa roj carbon additives thiab graphite electrodes txhais tau tias lawv tau pom tus cwj pwm ntawm lawv cov ntaub ntawv los ntawm ob tus neeg muag khoom thiab cov neeg siv kawg. Qhov kev tawm tswv yim voj voog yog qhov tseem ceeb rau kev tsim khoom.

Peb kuj tseem pom ntau lub sij hawm ntev, kev sib koom tes kev cog lus tsis yog qhov chaw yuav khoom. Ib tus kws tsim hluav taws xob graphite tsis xav twv txiaj ntawm daim ntawv sib tw zoo hloov lub hli-rau-hli. Lawv xav tau tus khub uas tuaj yeem lav qhov sib xws thiab ua haujlwm ntawm kev sib koom ua ke. Qhov no locks nyob rau hauv mov chains thiab tsa barriers rau nkag. Kev sib tw tshiab tsis yog lwm tus tar distiller hauv txoj kev; nws yog lwm cov ntaub ntawv xws li roj av, los yog txawm radical hloov li carbon-dawb steelmaking nyob rau hauv lub sij hawm ntev heev. Txog tam sim no, txawm li cas los xij, kev ua haujlwm thiab tus nqi qauv ntawm cov pa roj carbon monoxide yog ib qho nyuaj rau nws cov ntawv thov tseem ceeb.

Saib tom ntej: Cov lus nug tiag

Yog li qhov no tso peb nyob qhov twg? Lub neej yav tom ntej ntawm Npaj Cov Tar hinges rau ob peb nqe lus nug. Kev lag luam puas tuaj yeem txhim kho cov txiaj ntsig thiab kev ua tau zoo los ntawm cov khoom noj (coal) uas nws tus kheej hloov pauv? Cov nqi ib puag ncig puas tuaj yeem tswj hwm yam tsis muaj nqi khoom kawg ntawm kev ua lag luam? Thiab cov khoom puas tuaj yeem tuav nws cov txheej txheem kev tiv thaiv kev hloov pauv roj av, tshwj xeeb tshaj yog tias cov nqi roj hloov pauv?

Cov txheej txheem thev naus laus zis yuav zoo li tsom mus rau kev kwv yees kwv yees-siv cov ntaub ntawv feedstock los ua qauv distillation tshwm sim ua ntej batch txawm khiav-thiab txawm tias qhov sib cais molecular kom rho tawm tus nqi siab tshaj plaws los ntawm txhua feem. Cov eco tiam sis yuav thawb mus rau tag nrho cov nyiaj tshuav nyiaj li cas thiab tej zaum carbon capture kev koom ua ke ntawm cov nroj tsuag coking, uas yuav yog ib tug kev ua si-hloov rau lub lifecycle footprint.

Thaum kawg, nws yog kev lag luam uas ua rau nws cov khoom siv tawv nqaij. Lub sij hawm Npaj Cov Tar yog evolved los ntawm ib tug yooj yim txheej txheem cov khoom mus rau hauv ib tug xaiv, kev ua tau zoo-tseem ceeb tivthaiv nyob rau hauv ib tug high-tech mov saw. Nws qhov kev cuam tshuam tam sim no khi ncaj qha rau qhov zoo thiab kev tsim kho tshiab hauv cov khoom siv carbon kawg, txawm tias yog lub tshuab hluav taws xob loj uas siv lub tshuab steel lossis lub me me anode hauv EV roj teeb. Nws tsawg dua txog kev khawb cov thee thiab ntau ntxiv txog engineering molecules. Cov neeg ua si uas nkag siab txog qhov kev hloov pauv, uas muaj kev paub dhau los ntawm cov saw hlau, yog cov uas yuav txhais cov qauv, tsis yog ua raws li lawv.
