Kūkākūkā e pili ana i ke kumu kūʻai a me ka hoʻonui ʻana i ke kumu kūʻai o ka Petroleum Coke

Hua'ōlelo: kiʻekiʻe sulfur coke, sulfur coke haʻahaʻa, kumukūʻai optimization, sulfur content

Logic: aia kahi ākea nui ma waena o ke kumukūʻai kūloko o ka coke sulfur petroleum kiʻekiʻe a haʻahaʻa, a ʻo ke kumukūʻai i hoʻololi ʻia me ka hoʻololi ʻana o ka index ʻaʻole like like, ʻoi aku ka kiʻekiʻe o ka sulfur content o ka huahana, ʻoi aku ka haʻahaʻa o kona kumukūʻai.No laila, ʻoi aku ka maikaʻi o nā ʻoihana e hoʻohana i ka ratio like ʻole o ka sulfur coke kiʻekiʻe a me nā huahana sulfur haʻahaʻa e hōʻemi i ke kumukūʻai kūʻai i loko o ka pae o nā hōʻailona.

I ka makahiki 2021, e kiʻekiʻe ke kumukūʻai o ka petroleum coke i nā makahiki i hala iho nei.No nā ʻoihana o lalo, pili ke kumu kūʻai kiʻekiʻe me ke kumu kūʻai kiʻekiʻe, ʻo ia hoʻi, ka loaʻa kālā hoʻokō.No laila, pehea e hoʻonui ai i ke kumukūʻai e lilo i kumu nui e pili ana i ka hana o nā ʻoihana.Hōʻike ka Figure 1 i ka hoʻololi a me ka hoʻohālikelike ʻana o ke kumukūʻai ʻaila coke kūloko i nā makahiki i hala.Hiki iā mākou ke ʻike i ke kumukūʻai kiʻekiʻe ma 2021.

Kiʻi 1 Kūʻai kumu kūʻai o ka petroleum coke i nā makahiki

Hōʻike ka Kiʻi 2 i ka pakuhi kumukūʻai o nā ʻano ʻano coke ʻaila home.ʻO ke kumukūʻai o ka coke medium a me ka haʻahaʻa sulfur coke ka nui o ka hoʻoponopono ʻana a me ka laulā hoʻoponopono ākea, ʻoiai ke kumukūʻai o 4 # high sulfur coke i mālama ʻia ma kahi o 1500 yuan / ton me kahi hoʻololi liʻiliʻi.ʻO ka loli pinepine a me ka nui o ke kumukūʻai ʻaʻole ia ka mea a mākou e makemake ai e ʻike no nā ʻoihana o lalo, ʻoi aku ka hopena o ka piʻi ʻana o ke kumukūʻai superimposed.Ma ke kumu o ka hōʻoia ʻana i ka maikaʻi o ka huahana, ʻo ka hōʻemi ʻana a me ka hoʻonui ʻana i ke kumukūʻai ua lilo i wahi ʻeha no nā ʻoihana coke petroleum downstream.

Kiʻi 2 Ka pakuhi kumu kūʻai o ka aila coke hale o nā ʻano hoʻohālike like ʻole

Hōʻike ka Figure 3 i ka sulfur index a me nā hoʻololi kumukūʻai i loaʻa ma hope o ka sulfur coke kiʻekiʻe me 5% sulfur maʻiʻo i hui pū ʻia me ka sulfur coke haʻahaʻa me 1.5%, 0.6% a me 0.35% sulfur maʻiʻo ma nā ʻano like ʻole.No ka mea, he mea nui ka maʻiʻo o ka sulfur coke kiʻekiʻe e hoʻohaʻahaʻa i ke kumukūʻai, akā e hoʻonui ia i ka sulfur content i ka maikaʻi o ka huahana, pono ia i loko o ka pae kuhikuhi kūpono loa.No ka loaʻa ʻana o ka lakene hui maikaʻi loa e hoʻokō i ka hoʻonui kumukūʻai.

Ma ka huahelu 3, no ke koho ana i ka abscissa o ka nui sulfur coke ratio, pela ka ratio o ekolu ano o ka sulfur maʻiʻo i loko o ka hopena a me ka hope kumukuai convergent, a hiki i ke kumu kuai laina, ma ka aoao akau o ka laina no ka sulfur maʻiʻo. ka intersection mākou i manao equilibrium, hiki iā mākou ke ʻike mai ka helu 3 me 5% sulfur maʻiʻo a me ka lākiō o ʻokoʻa sulfur maʻiʻo nā hōʻailona o ka huahana, Me ka ho'ēmiʻana o kekahi huahana sulfur maʻiʻo kuhikuhipuʻuone o equilibrium mau neʻe i ka akau i ka manawa like, no hoi ma ke neʻe nei i luna, no laila, ma ke kumu kūʻai optimization o koho huahana a mai koho i ka sulfur maʻiʻo o ka mea kiʻekiʻe a me ka haʻahaʻa sulfur maʻiʻo i loko o ka like 'ole o ka hui 'ana, akā, e like me maoli pono, me ka haʻahaʻa haʻahaʻa kumu kūʻai o kiʻekiʻe sulfur maʻiʻo o kekahi mau huahana hui. .

No ka laʻana, pono mākou i ka petroleum coke me 2.5% sulfur content ma ke ʻano he kuhikuhi hope.Ma ka Figure 3, hiki iā mākou ke ʻike i ke kumukūʻai maikaʻi loa e pili ana i ka RMB 2550 / ton ma hope o ka ratio o 30% petroleum coke me 5% sulfur content i 70% petroleum coke me 1.5% sulfur content.Me ka noʻonoʻo ʻole i nā kumu ʻē aʻe, ʻo ke kumukūʻai ma kahi o 50-100 yuan / ton ka haʻahaʻa ma mua o nā huahana me ka index like ma ka mākeke.No laila, he koho maikaʻi ia no nā ʻoihana e hoʻopaʻa i ke kumukūʻai e hoʻohui i nā huahana me nā index ʻokoʻa ma lalo o nā kūlana kūpono.
