Nyocha nke Isi Oriri Ike na Mmetụta Gburugburu Ebe Obibi na Mmepụta Mmanụ Ala Graphitized Coke

I. Usoro Nri Ike Isi

  1. Ọgwụgwọ Graphitization dị elu
    Usoro nhazi ihe osise bụ isi, nke chọrọ ka okpomọkụ ruo 2,800–3,000°C iji gbanwee carbon na-abụghị graphitic dị na coke petroleum ka ọ bụrụ nhazi kristal graphite. Oge a na-ewe ike nke ukwuu, ebe ọkụ Acheson ọdịnala na-eri 6,000–8,000 kWh kwa tọn nke ọkụ eletrik. Igwe ọkụ kwụ ọtọ ọhụrụ na-aga n'ihu na-ebelata nke a ruo 3,000–4,000 kWh kwa tọn, ọ bụ ezie na ọnụ ahịa ike ka bụ 50%–60% nke mmefu mmepụta niile.
  2. Okpomọkụ na Oyi Ogologo Oge
    Usoro ọdịnala na-ewe ụbọchị 5-7 kwa otu, ebe ọkụ ọhụrụ na-ebelata nke a ruo awa 24-48. Agbanyeghị, oyi ka chọrọ awa 480 nke ikuku oyi sitere n'okike. Mmalite ọkụ na mmechi ugboro ugboro na-eduga na mkpofu ike okpomọkụ, na-abawanye oriri ike.
  3. Oriri Ike n'ime Usoro Enyemaka
    • Ịkụcha na Ịgweri: A ga-akụri koke mmanụ ala ruo nha ihe dị ka 10-20 mm, ebe ịgweri ya na-eri ike eletriki dị ukwuu.
    • Ịsacha Asịd (Ịsacha Asịd): A na-eji ihe ndị e ji kemikal mee ewepụ ihe ndị na-adịghị mma, na-eme ka usoro ahụ sie ike n'enweghị ọkụ eletrik kpọmkwem.
    • Nchedo Gas: A na-enye gas ndị na-anaghị arụ ọrụ dịka argon ma ọ bụ nitrogen mgbe niile iji gbochie oxidation, nke chọrọ ka akụrụngwa ọkọnọ gas na-arụ ọrụ mgbe niile.

II. Nyocha Mmetụta Gburugburu Ebe Obibi

  1. Mwepụ Gas Mkpofu
    • Ọkwa Okpomọkụ Dị Ala (Okpomọkụ Ụlọ–1,200°C): Calcium oxide (CaO) dị na ihe e ji emeju ihe (calcined petroleum coke) na-emeghachi omume na carbon iji mepụta carbon monoxide (CO), ebe mmebi okpomọkụ na-emepụta methane (CH₄) na mwepụta hydrocarbon ndị ọzọ.
    • Ọkwa Okpomọkụ Dị Elu (1,200–2,800°C): Sọlfọ, ntụ, na ihe na-agbanwe agbanwe na-ere ere, na-emepụta ihe dị n'ime ya na sọlfọdọks (SO₂). Ọ bụrụ na e nweghị ọgwụgwọ dị irè, mwepụta SO₂ na-eme ka mmiri ozuzo dị n'ime ya ghara ịdị mma, ebe ihe dị n'ime ya na-emebi ịdị mma nke ikuku.
    • Usoro Mbelata: Ngwakọta nke ihe ndị na-ekewapụ ikuku cyclone, ihe nhicha alkaline nke ọkwa atọ, na ihe nzacha ụlọ akpa na-eme ka ikuku e tinyere n'ọrụ ruo n'ókè iwu kwadoro.
  2. Mmiri mkpofu na ihe mkpofu siri ike
    • Mmiri mkpofu: Ịsa ihe mkpofu acid na-emepụta mmiri mkpofu acidic nke chọrọ nkwụsịtụ, ebe mmiri oyi nke akụrụngwa nwere ihe ndị na-emerụ mmanụ nke na-achọ ikewapụ na mgbake.
    • Mkpofu siri ike: A na-etinye ihe e ji ekpuchi ihe nke nwere ike iguzogide ihe na-adịghị mma n'ime akpa maka ọrịre ma ọ bụ ikpofu ihe mkpofu, nke na-ebute ihe egwu nke mmetọ ala ma ọ bụrụ na ejighị ya nke ọma.
  3. Mmetọ Uzuzu
    A na-emepụta uzuzu n'oge a na-egwepịa ihe, na-enyocha ihe, na mgbe a na-asacha ọkụ. Ọ bụrụ na e nweghị usoro nchịkọta e tinyere n'ime ya, ọ na-etinye ahụike ndị ọrụ n'ihe ize ndụ ma na-emerụ gburugburu ebe obibi.
    Usoro Njikwa: A na-eji kreen mmiri, mkpuchi, na ihe nzacha akpa ejide uzuzu tupu a wụpụ ya site na ikpo ikuku.
  4. Oriri Akụrụngwa na Mwepụ Carbon
    • Akụrụngwa Mmiri: A na-eji mmiri dị mkpa eme ihe maka ịjụ oyi na nhicha, na-eme ka nrụgide mmiri ka njọ n'ógbè kpọrọ nkụ.
    • Nhazi Ike: Ịdabere na ọkụ eletrik sitere na mmanụ ọkụ na-eduga na mwepụ CO₂. Dịka ọmụmaatụ, imepụta otu tọn nke elektrọd graphite na-eri tọn 1.17 nke kol nkịtị, na-eme ka akara ụkwụ carbon dịkwuo elu n'ụzọ na-apụtaghị ìhè.

III. Atụmatụ Mmeghachi Omume Ụlọ Ọrụ

  1. Nkwalite Teknụzụ
    • Kwalite ọkụ ọkụ kwụ ọtọ ọhụrụ na-aga n'ihu iji belata okirikiri ma belata oriri ike (ojiji ọkụ eletrik na-agbada ruo 3,500 kWh kwa tọn).
    • Jiri teknụzụ eserese microwave mee ihe maka ikpo ọkụ ngwa ngwa (ihe na-erughị otu awa) yana nnyefe ike lekwasịrị anya.
  2. Ọchịchị Gburugburu Ebe Obibi
    • Ọgwụgwọ Gas Mkpofu: Gbaa ọkụ na ikuku na-ekupụ n'okpomọkụ dị ala ma jiri nchịkọta emechie ya na nhicha dị iche iche n'okpomọkụ dị elu.
    • Imegharị Mmiri Mkpofu: Mejuputa usoro iji mmiri eme ihe iji belata mmiri a na-aṅụ.
    • Nhazi Mkpofu Siri Ike: Jiri ihe ndị na-ejupụta ihe na-adịghị mma mee ihe dị ka ihe na-emegharị ihe maka osisi ígwè.
  3. Mmekọrịta Amụma na Ụlọ Ọrụ Mmepụta Ihe
    • Mee ihe dịka iwu si dịIwu Mgbochi na Njikwa Mmetọ IkukunaIwu Mgbochi na Njikwa Mmetọ Mmiriiji manye ụkpụrụ ikuku siri ike.
    • Mee ka ọrụ ihe anode agbakwunyere rụọ ọrụ nke ọma site n'iwulite ikike nhazi eserese n'ime ụlọ iji belata ntụkwasị obi na ndị na-ebubata ngwaahịa mpụga ma belata mmetọ metụtara njem.

IV. Mmechi

Mmepụta nke coke mmanụ ala graphitized bụ usoro siri ike ma na-emetọ ihe nke ukwuu, ebe oriri ike na-etinye uche na nhazi okpomọkụ dị elu na mmetụta gburugburu ebe obibi nke gas mkpofu, mmiri, ihe mkpofu siri ike, na mmetọ uzuzu. Ụlọ ọrụ ahụ na-ebelata mmetụta ndị a site na mmepe teknụzụ (dịka ọmụmaatụ, ọkụ na-aga n'ihu, ikpo ọkụ microwave), ọchịchị gburugburu ebe obibi (nhicha ọtụtụ ọkwa, imegharị ihe onwunwe), na nhazi amụma (ụkpụrụ mwepụ, mmepụta agbakwunyere). Agbanyeghị, nhazi na-aga n'ihu nke usoro ike - dịka ijikọ ọkụ eletrik a na-emegharị emegharị - ka dị oke mkpa maka inweta mmepe na-adịgide adịgide.
