Chii chinonzi asphalt coke?

Asphalt Coke, anowanzo rondedzwa sepetroleum coke kana kungoita pet coke, ishebhu rinotorwa kubva mukunatswa kwemafuta anorema asina kuchena. Kunyange zvingaenzani zvakafanana neasphalt inoshandiswa kumigwagwa yekurongedza, asphalt coke is a yakasimba carbonaceous zvinhu zvine midziyo yakasarudzika uye zvinoshandiswa. Iyo yakawana mukurumbira mune dzakasiyana-siyana maindasitiri nekuda kweiyo yakakwira kabhoni zvemukati uye simba density. Ichi chinyorwa chinoongorora kuti chii chinonzi asphalt coke, maitiro ayo ekugadzira, mhando, zvikumbiro, uye kufunga kwezvakatipoteredza kwakabatana nekushandiswa kwaro.

Izvo zvekutanga zveAsphalt coke

Asphalt coke, dema, uye yakasimba zvinhu zvakanyanyisa kuumbwa kabhoni, pamwe chete nemitsetse yesarufa, hydrogen, uye simbi. Iyo byproduct yekukora maitiro, nzira inoshandiswa mumafuta ezvekuwedzera kusimudzira mafuta asina kuchena, zvigadzirwa zvakakosha sepeturu uye dizil. Iyo yakasara zvinhu kubva pane izvi zvinosimbisa mu asphalt coke, yakanyanya kugadzikana uye ine simba-pfuma.

Ipo izwi rekuti "asphalt coke" rinogona kuratidza chinongedzo kune asphalt anoshandiswa pakuvaka mumugwagwa, ivo vaviri vakasiyana. Asphalt yekuvhara iri fomu-yakasimba fomu yePetroleum, nepo asphalt coke is a ligid, kabhoni-inorema-inorema yakasimba.

Asphalt Conta inogadzirwa sei?

Asphalt coke yakagadzirwa panguva yekunatsa yemafuta anorema asina kuchena, kunyanya mukunonoka kudzora zvikamu. Maitiro acho anosanganisira:

1. Kupisa:Mafuta anorema asina kuchena anotsveneswa kupisa (500-550 ° C) mune coker unit.
2. Kuora Kwekuuraya:Pasi pokupisa uye kumanikidzwa, refu hydrocarb ketani dzinopwanya kuita madiki madiki, kupatsanura zvigadzirwa zvakareruka senge peturu uye dizil kubva pakurima zvakasara.
3. Kukanda:Iyo inosara hydrocarbons inosimbisa mune yakasimba, kabhoni-yakapfuma zvinhu zvinozivikanwa seasphalt coke.
4. Kutonhora uye Unganidzo:Akamboremerwa, iyo coke yakaunganidzwa, yakapwanywa, uye yaiwanzoongororwa kuti isangane nezvayo zvinodikanwa zveindasitiri.

Mhando dze asphalt coke

Asphalt Coke yakakamurwa mumhando dzakasiyana dzakavakirwa pachimiro charo uye application:

1. Green Coke:
   • Fomu yakasviba yeasphalt coke, zvakananga kubudiswa kubva pakukora maitiro.
   • Ine yakakwira mazinga ehuremesi zvine musoro uye kunyorova.
   • Inowanzoshandiswa seyakafa yekubhadhara kanenge calcination kana seinobva mafuta sosi mumaindasitiri.
2. Calced Coke:
   • Green coke ine pasi pe calcination, kurapwa kwakanyanya kwekubvisa zvinhu zvisina kunaka.
   • Inozivikanwa nekuchena kwayo uye yakakwirira kabhoni zvemukati.
   • Inonyanya kushandiswa mukugadzirwa kwe aluminium, simbi, uye maElectrodes.
3. Sindano Coke:
   • Fomu yakakosha yeCoke ine tsono-kunge crystalline chimiro.
   • Yakakosha mukugadzira yeGraphite Electrodes Eserce arc machira.
4. Fuel-Giredhi Coke:
   • Yakadzika-giredhi asphalt coke inoshandiswa zvakanyanya sehuni mune zvidiki zvidyarwa uye coment kilns nekuda kweiyo yakakwirira yeCalardif.

Zvikumbiro zveasphalt coke

1. Aluminium Indasitiri:
   Calcined asphalt coke chiitiko chakakosha mukugadzirwa kweAnods anoshandiswa muAluminium kunyudzwa.
2. Simbi Indasitiri:
   Sindano coke yakakosha yekugadzira graphite electrodes, iyo yakakosha muVigetsi arc machira ekurira.
3. Energy Sector:
   Fuel-Giredhi Coke inoshandiswa seimwe nzira kune marasha mune chizvarwa chechizvarwa uye kugadzirwa kwesimende, nekuda kwesimba rayo rakakwirira simba.
4. Indasitiri yeMakemikari:
   Asphalt Coke anoshanda seyakaisa zvinhu zvekugadzira makemikari uye maindasitiri carbon zvigadzirwa, zvakadai se kabhoni dema uye synthetic graphite.

Kufunga kwezvakatipoteredza

Pasinei nezvinokuvara zvacho, Asphalt Coke inouya neyakatonamara.

1. High carbon emissions:
   • Paakapiswa kunge mafuta, asphalt coke anoburitsa huwandu hwakakosha hweCarbon dioxide (CO2), zvinopa kudziya kwepasirese.
2. Kusvibiswa kwemhepo:
   • Sulfur yezvinyorwa mune asphalt coke inogona kutungamira kune iyo yekubuda kweSulfa dioxide (So2), ichikonzera nyaya dzemhepo dzemhepo uye acid inonaya.
3. Marara manejimendi:
   • Kubata kwakakodzera uye kuchengetwa kwakakosha kudzivirira kusvibiswa kwezvakatipoteredza, sekusvibiswa kwezvakatipoteredza, sekusarudzika kweasphalt kunogona kuve nesimbi inorema saVanadium ne nickel.

Kuedza kuri kuderedza kuti kuderedze iyi maitiro enzvimbo, sekurera tekinoroji yekuchenesa yeCoke kugadzirwa uye kuongorora dzimwe sarudzo dzekushandisa asphalt coke isingabatanidze kurwadzisa.

Mhedziso

Asphalt Coke inosimbisa maitiro ekunatsa oiri, kupa macomputations kupfuura iyo aluminium, simbi, uye maindasitiri esimba. Yayo yakakwirira kabhoni zvemukati uye density density inoita kuti ive yakakosha zvigadzirwa mumaindasitiri maitiro, kunyanya mumatunhu ayo zvimwe zvigadzirwa zvisingaiti kana mafuta mashoma.

Nekudaro, matambudziko akatipoteredza ane chekuita nekushandiswa kwayo anoratidza kukosha kwekutangisa manejimendi ane mutoro uye nekudzora tsoka dzayo dzezvemativi. Maindasitiri anovavarira kutsigirwa, Asphalt Coke anoenderera mberi nekutamba basa rakakosha mukuvhara musana pakati pekushandiswa kwezviratidzo uye nehutariri hwezvakatipoteredza.
