Ukususela ngo-Agasti, imakethi ye-petroleum coke yasekhaya iyonke ibirhweba kakuhle, kwaye indlela yokuthenga esezantsi izinzile, nto leyo eye yabangela ukuba uluhlu lwe-petroleum coke lweendawo zokucola kunye namazibuko lwehle ngokukhawuleza, kwaye ixabiso lentengiselwano ye-petroleum coke liye latshintsha-tshintsha. Imakethi yekota yesithathu ineengaphezulu kwesiqingatha, elandelayo ngotshintsho lwemarike kunye notshintsho lwemfuno kwixabiso le-petroleum coke iya kubonisa yiphi indlela?

Kutshanje, imeko-bume yokurhweba nge-petroleum coke yasekhaya intle ngakumbi, amashishini asezantsi afuna nje ukuthenga inkxaso inamandla, kwaye amanye amaxabiso e-petroleum coke abonisa ukuthambekela okuphezulu.

Ngokutsho kohlalutyo lwezibalo lwedatha yemarike yeLongzhong Information, ixabiso eliqhelekileyo le-petroleum coke yasekhaya ene-sulfur ephantsi yi-3257 yuan/ton, inyuke nge-2.2% ukusuka kwinyanga ephelileyo. Ukusebenza kwemfuno yemarike yezinto ze-electrode ezimbi kulungile, amashishini e-graphite electrode aqala ukuphucula indlela yokuthenga intle ngakumbi, ukuthunyelwa kwe-oyile yokucoca kakuhle. Ngenxa yokusebenza okunciphileyo kwemveliso kwezinye iindawo zokucoca, ukusebenza kokuthunyelwa ngokubanzi bekuzinzile, kwaye amashishini e-carbon angene kwimarike ukubuza iimpahla, nto leyo ebangela ukuba amaxabiso e-coke yokucoca anyuke.

Ixabiso lemarike le-medium sulfur petroleum coke liqhubekile nokunyuka ukuya kwi-2463 yuan/ton, ukunyuka kwe-103 yuan/ton okanye i-4.36%. Ngenxa yokulungiswa kwesalathisi sezinto eziluhlaza, umxholo wesalfure we-petroleum coke kwimarike yokucoca yasekuhlaleni uyaqhubeka nokunyuka, kwaye imveliso ye-shot coke kwiPhondo laseShandong itshintshwa ngokwahlukeneyo, kwaye ukunikezelwa kwe-medium sulfur petroleum coke kwimarike kuyancipha. Ukusebenza kwesalathisi se-petroleum coke kwezinye iindawo zokucoca i-Sinopec ecaleni komlambo kulungile, kwaye umdla wokuthenga wamashishini amabi unamandla, nto leyo eqhuba ixabiso le-medium-sulfur petroleum coke ecaleni komlambo ukuba liqhubeke linyuka.

Imarike ye-coke yepetroleum ene-sulfur ephezulu ngokusisiseko igcine umkhwa ozinzileyo noguquguqukayo kancinci, kwaye ixabiso le-coke yepetroleum eveliswayo nethengiswa kakuhle kwiindawo eziphambili zokucola liqhubekile nokunyuka kancinci; Ukuthunyelwa kwimarike yokucola kuyehla, amashishini atshileyo eempahla angena kwimarike enesimo sengqondo sokuthenga ngononophelo, kwaye iindawo zokucola zithumela ngenkuthalo amaxabiso athile e-coke ehla kuluhlu oluncinci.

Kutshanje, umdla wamashishini e-silicon wokuthenga uphezulu, imakethi ye-aluminium carbon irhweba kakuhle, kwaye imfuno yemakethi yee-electrode ze-graphite kunye nezixhobo ze-electrode ezingalunganga zilungile kwiimpahla ezithunyelwa kwimakethi ye-petroleum coke, kwaye iindawo zokucocisa zasekhaya kunye ne-petroleum coke ezingenisiweyo zibonisa indawo yokugcina izinto ngexesha elinye.

Ngokwedatha yophando lwemarike evela kwiLongzhong Information, ukususela phakathi ku-Agasti, uluhlu lwe-petroleum coke kumazibuko amakhulu asekhaya lwehle lwaya kwi-4.93 yezigidi zeetoni, lwehla nge-6.24% ukusuka kwinyanga ephelileyo. Ukusukela ngo-Agasti, inani le-petroleum coke esandul’ ukufika kwizibuko liye lehla kakhulu, kwaye inani elincinci le-coke engeniswe kwizibuko ligxile kakhulu kumazibuko aseShandong naseGuangxi. Okwangoku, imithombo yeempahla ezithengiswayo ikakhulu yi-United States, iRashiya kunye ne-petroleum coke ene-sulfur ephantsi. Amashishini e-Silicon carbide anesidingo esihle sokuthengwa kwe-pellet coke ephakathi nephezulu, nto leyo enyusa ixabiso le-port spot pellet coke. Inzuzo yexabiso le-petroleum coke engeniswe kwi-carbon grade icacile xa ithelekiswa ne-petroleum coke elinganayo yasekhaya, kwaye umdla wokuthengwa kwamashishini e-carbon asezantsi uselungile, uxhasa ixabiso le-coke ethile engeniswe kwi-intanethi.

I-petroleum coke yasekhaya enezixhobo zokulungisa kwangethuba iqalise ukuvelisa kwakhona kwaye inika ukonyuka okuncinci, imakethi ikwimeko yokukhula okubini kobonelelo kunye nemfuno, kwaye i-refinery ithunyelwa kwaye ithengiswa ngokukhutheleyo, kwaye uluhlu lwempahla yesampulu ye-petroleum coke refinery yeshishini lugcinwe malunga neetoni ezili-100,000.

Uqikelelo lwemarike yexesha elizayo:

Ngenxa yotshintsho oluqhubekayo kwisalathisi sezinto eziluhlaza ze-petroleum coke, kulindeleke ukuba ukuhanjiswa kwe-petroleum coke ene-sulfur ephantsi kunokuncipha, kwaye inani lokuhanjiswa kwempahla ngokubanzi ene-sulfur ephezulu liyakhula, nangona icala lemfuno yasekhaya linamandla kakhulu, kodwa amashishini kunye nabarhwebi abasezantsi balumkile ngakumbi ukungena kwimarike. Ukongeza, ezinye ii-petroleum coke ezingenisiweyo zinezibonelelo ezicacileyo kunezixhobo zasekhaya, nto leyo enyanzelisa ixabiso lezinye iimpahla zasekhaya ukuba zihlale zisezantsi.

Ngasekupheleni kuka-Agasti, imakethi ye-petroleum coke yayicwangciswe kakhulu, kwaye phantsi kwesikhokelo sokubonelela kunye nemfuno, amaxabiso e-coke yokucola asekhaya okanye ukuguquguquka okuncinci okuzinzileyo, ukuthunyelwa kwe-port petroleum coke bekukuhle, kwaye amanye amaxabiso e-coke ayesenethuba elincinci lokunyuka.
