ʻO nā hydrocarbons aromatic ke kumu no nā ʻano huahana like ʻole, ʻo ka mea nui loa i hoʻohana ʻia i ka hana ʻana i nā dyes, polyurethanes a me nā fiber synthetic.ʻO ka Petrochemical Industry kahi ʻoihana piha loa, akā he huahana koʻikoʻi ka ethylene, ʻo ia hoʻi nā huahana olefin nui.ʻO ka hana ʻana o ka ethylene makahiki honua ma 2012 ma kahi o 143 miliona tons.Ma ka mōʻaukala, ʻo ka hoʻolako ʻana a me ka ʻai ʻana i ka ethylene ua hoʻomalu ʻia e ka United States, Western Europe a me Iapana.Mai ka 2009 a i ʻole 2010, akā naʻe, ua loli ke kūlana, me ka neʻe ʻana o ka hana a me ka hoʻohana ʻana i ka Middle East a me Asia.ʻO kēia manawa wale nō i hoʻihoʻi mai ka shale-gas boom o ʻAmelika i ke koena o ka leverage hoʻokele waiwai i ke kaulike a hoʻoulu i ka piʻi nui o ka mana hana hou ma ʻAmelika ʻĀkau.

Loaʻa i nā Ngls ka ethane, propane, butane, isobutene, a me ka pentana.He kūpono kekahi o lākou no ka ʻoihana petrochemical.Ua ʻike mua ʻia ʻo Ngls ma ke ʻano he haʻahaʻa haʻahaʻa i hoʻohui ʻia e ka huahana e puhi ana ma kahi kokoke i ke poʻo punawai.I kēia mau lā, akā naʻe, ua ʻike pono nā kānaka i kona waiwai ma ke ʻano he petrochemical maka.ʻO kēia hoʻololi ka mea i hoʻoikaika i ka hoʻihoʻi ʻana ma ʻAmelika ʻĀkau, a me ka ʻoihana petrochemical US.

He aha ke ʻano o ka hoʻihoʻi ʻana o ka ʻoihana petrochemical no ka mākeke valve?

ʻO ka hoʻihoʻi ʻana i ka ʻoihana petrochemical US he nūhou maikaʻi no nā mea hoʻolako lako waiwai, me nā valves.Loaʻa nā manawa ʻoihana ma kēlā me kēia ʻano o ka hoʻomohala ʻana i ka ikehu.

ʻO ka hoʻomau ʻana i ka hoʻohana ʻana i ka shale gas-waiwai i ka condensate kinoea maoli (NGLs) ua alakaʻi i ka wehe ʻana i nā papahana wili he nui, ka hopena i ke koi ʻana i nā ʻano kīwī punawai he nui.Ma kahi o 1,700 mau rigs e hana ana ma ʻAmelika Hui Pū ʻIa - ʻoi aku ka nui ma mua o ke koena o ka honua i hui pū ʻia - koi ʻia a ikaika loa ka koi no nā kīwaha poʻo.

Pono ʻo Ngls no ka hana ʻana i ka petrochemical i kahi pūnaewele pipeline i hoʻolaʻa ʻia no ka lawe ʻana iā lākou i nā wahi hana, e like me nā ʻāpana ʻāpana a i ʻole nā ​​​​mea kanu petrochemical.ʻO ka hui pū ʻana a me ka pipeline kaʻa i hāʻawi i ka mākeke i ka valve pipeline, ʻoi aku ka nui o ke kahawai kahe piha a "hiki ke hele i ka bead maʻemaʻe" i ka pahu pōleʻa, ke koi nui ka ʻīpuka.A pono e hui pū ʻia nā mea hana i kēia mau valve me ka hāʻawi ʻana i kahi manawa ʻoihana hoihoi no ka mākeke mea kūʻai.

ʻO nā mea kanu Petrochemical nā mea hana maʻalahi a paʻakikī.Hiki ke kiʻekiʻe i ka 1-2 miliona tons ka puka makahiki o kahi mea kanu petrochemical hou.ʻO ke kumu kūʻai o ka mea kanu e pili ana i kona nui a me kona wahi, akā aia ia ma kahi o $ 3 biliona a i $ 4 biliona.ʻO ke kumukūʻai o ka valve no ka mea kanu ma kahi o $35 miliona.ʻOiai ua ʻike maopopo ʻia e hāʻawi nā mea kanu hou i nā manawa ʻoihana waiwai a piha loa no ka ʻoihana valve, ʻo ka hoʻonui ʻana i nā mea kanu a me ka hoʻoponopono hou ʻana e hoʻokipa i nā mea hana hou he mea nui hoʻi, ʻoi aku ka nui ma ka mākeke US.Aneane e hoʻohana ʻia nā ʻano valve a pau, me nā kiwi piʻi kiʻekiʻe i hoʻohana ʻia i nā hale hana no ka pale ʻana i nā compressors.
