【Alakaʻi】I kēia pule, ua hoʻomaikaʻi iki ʻia ke ʻano hana holoʻokoʻa o ke kaulahao ʻoihana propylene. Ke noho mālie nei ka ʻaoʻao lako, ʻoiai ua piʻi aʻe ka helu helu hana piha o nā huahana downstream. Me ka hoʻomaikaʻi ʻia ʻana o nā palena waiwai o kekahi mau huahana downstream, ua piʻi aʻe ka ʻae ʻana o nā hale hana downstream i nā kumukūʻai propylene, e hoʻoikaika ana i ke kākoʻo no ke koi propylene a hāʻawi i kahi hoʻoikaika i ka mākeke propylene.
I kēia pule, ua hoʻi hou nā kumukūʻai mākeke propylene kūloko ma hope o ka paʻi ʻana i ka lalo, me ka pāʻani lako a me ke koi o ka mākeke ma ke ʻano he hiʻohiʻona nui. ʻO ke kumukūʻai awelika hebedoma o ka propylene ma Shandong i kēia pule he 5,738 yuan/ton, he emi ʻana o 0.95% i kēlā me kēia mahina; ʻo ke kumukūʻai awelika hebedoma ma Kina Hikina he 5,855 yuan/ton, he emi ʻana o 1.01% i kēlā me kēia mahina.
I kēia pule, ua hui pū ʻia nā ʻano kumukūʻai o ke kaulahao ʻoihana me ka laulā o ka loli holoʻokoʻa. Ua hōʻike nā kumukūʻai o nā mea maka nui i nā piʻi a me nā iho like ʻole me ka volatility liʻiliʻi, me ka hopena palena i nā kumukūʻai propylene. Ua hāʻule iki ke kumukūʻai propylene awelika i kēlā me kēia mahina a ua piʻi hou ma hope o ka paʻi ʻana i ka lalo. Ua piʻi a iho nā kumukūʻai o nā derivatives downstream: i waena o lākou, ua piʻi nui ke kumukūʻai o ka propylene oxide, ʻoiai ua hāʻule nui ke kumukūʻai o ka acrylic acid. Ua hoʻopiha hou ka hapa nui o nā hale hana downstream i nā waihona ma nā kumukūʻai haʻahaʻa.
Piʻi ka nui o ka hana o ka ʻoihana me ka emi ʻana o ka lako.
I kēia pule, ua hōʻea ka nui o ka hana propylene i 79.57%, he piʻi ʻana o 0.97 pakeneka mai ka pule i hala. I loko o ka pule, ua mālama ʻia nā ʻāpana PDH o Haiwei lāua ʻo Juzhengyuan, a me ka ʻāpana MTO o Hengtong, kahi i hoʻonui iki ʻia ai ka lako mākeke. Ua mālama ka ʻoihana propylene i kahi kūlana lako palupalu, a ua hoʻoponopono kekahi mau ʻāpana i kā lākou ukana hana, e alakaʻi ana i ka piʻi iki ʻana o ka nui o ka hana o ka ʻoihana i kēia pule.
Piʻi ka Downstream Comprehensive Operating Rate Index, Hoʻomaikaʻi ka Propylene Cost
I kēia pule, ua kū ka helu kuhikuhi hana piha o nā ʻoihana propylene downstream ma 66.31%, he piʻi ʻana o 0.45 pakeneka mai ka pule i hala. I waena o lākou, ua piʻi nui nā helu hana o ka pauka PP a me ka acrylonitrile, ʻoiai ua emi nui nā helu o ka phenol-ketone a me ka acrylic acid. I kēia pule, ua piʻi ka helu kuhikuhi hana holoʻokoʻa downstream, e hoʻoulu ana i ke koi paʻa no ka propylene mai nā hale hana downstream. Eia kekahi, me nā kumukūʻai propylene ma kahi haʻahaʻa a me nā palena waiwai o kekahi mau huahana downstream e hoʻomaikaʻi ana, ua piʻi ka hoihoi o ke kūʻai ʻana i downstream no ka propylene, e hāʻawi ana i kahi hoʻonui iki i ke koi propylene.
Hoʻomaikaʻi iki ka loaʻa kālā o nā huahana ma lalo, e hoʻonui ana i ka ʻae ʻia ʻana o nā kumukūʻai Propylene
I kēia pule, ua hui pū ʻia ka loaʻa kālā o nā huahana propylene downstream. Me ke kikowaena kumukūʻai propylene ma kahi pae haʻahaʻa, ua emi ke kaomi kumukūʻai o kekahi mau huahana downstream. ʻO ke kikoʻī, ua neʻe ka pauka PP mai ka loaʻa kālā a i ka pohō i kēia pule, ʻoiai ua piʻi ka loaʻa kālā o PO (propylene oxide). Ua hoʻonui ʻia ka palena pohō o n-butanol, ʻoiai ua emi ka 2-ethylhexanol, acrylonitrile, a me phenol-ketone. Eia kekahi, ua emi ka loaʻa kālā o ka waikawa acrylic a me ka propylene-based ECH. Ma keʻano holoʻokoʻa, ua hoʻomaikaʻi iki ka loaʻa kālā o nā huahana downstream akā maʻalahi, kahi i hoʻonui ai i ko lākou ʻae ʻana i nā kumukūʻai propylene.
