Hua'ōlelo: high sulfur coke, low sulfur coke, cost 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 ka hoʻohana ʻana o nā ʻoihana i ka lakene like ʻole o ka sulfur coke kiʻekiʻe a me nā huahana sulfur haʻahaʻa e hōʻemi i ke kumukūʻai kūʻai i loko o ka pae i ʻae ʻia 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 Kiʻi 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 ʻaila coke i nā makahiki
Hōʻike ke kiʻi 2 i ka pakuhi kumu kūʻai o nā ʻano coke ʻaila home. ʻO ke kumukūʻai o ka coke liʻiliʻi a me ka liʻiliʻi sulfur ka nui o ka hoʻoponopono ʻana a me kahi ākea ākea 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 nā 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 Papa kumu kūʻai o ka ʻaila ʻaila coke o nā ʻano 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 i nā ʻano like ʻole. No ka mea, he mea nui ka maʻiʻo o ka coke sulfur 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 kumukuai laina, ma ka aoao akau o ka laina no ka sulfur maʻiʻo. ka intersection a mākou i manaʻo ai equilibrium, hiki iā mākou ke ʻike mai ka helu 3 me 5% sulfur maʻiʻo a me ka lākiō o nā mea hōʻailona sulfur maʻiʻo like ʻole o ka huahana, Me ka hōʻemi ʻana o kekahi huahana sulfur maʻiʻo helu helu o ke kaulike e neʻe mau i ka ʻākau i ka manawa like, pū kekahi ke neʻe nei i luna, no laila, i ke kumu kūʻai optimization o koho huahana a me ka ole koho i ka sulfur maʻiʻo o ka mea kiekie loa a me ka haʻahaʻa sulfur maʻiʻo i loko o ka like ole like o ka huikau, akā, e like me maoli pono, me ka haʻahaʻa kumu kūʻai o kiʻekiʻe sulfur maʻiʻo o kekahi mau huahana ua hui pu ia. .
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 a 70% petroleum coke me 1.5% sulfur content. Me ka noʻonoʻo ʻole i nā kumu ʻē aʻe, ʻo ke kumukūʻai e pili ana i ka 50-100 yuan / ton haʻahaʻa ma mua o nā huahana me ka papa kuhikuhi 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.
