[Ntuziaka]: Na ngwụcha ọnwa Juun, mmechi a na-atụghị anya ya nke ngwa ahịa propylene mere otu otu, nke dị mma maka akụkụ ọkọnọ, ebe ịnụ ọkụ n'obi nke ngwaahịa ndị dị n'okpuru ala malitere, ọnụ ahịa ahịa kwụsịrị ịda, ruo na Julaị 14, azụmahịa a na-emekarị nke ọnụ ahịa ahịa Shandong propylene bụ yuan 6480-6500 kwa tọn, azụmahịa a na-emekarị nke ahịa East China bụ yuan 6350-6350 kwa tọn.

N'ime usoro a, ahịa propylene nke obodo akwụsịla ịda ma gbakee, ihe ndị na-akwado mmụba ahịa bụ isi ihe dị mkpa maka ọkọnọ na ọchịchọ. Makro, ọnụahịa mmanụ mba ụwa amụbaala, ihe ndị bụ isi dị mma bụ: data mmụba ọnụahịa nke United States dị mma, Federal Reserve ga-anọgide na-ebuli nrụgide ọnụego ọmụrụ nwa belatara, mbelata mmepụta ọzọ nke Saudi Arabia mere ka ikuku dị mma na-aga n'ihu n'ahịa. N'otu oge ahụ, ebe a na-adọba ụgbọala nwa oge nke ngwaọrụ Qingdao Jinneng, Wangtong, na Zhenghe propylene na mpaghara ahụ, ebe a malitebeghị ngwaọrụ mmezi ebe a na-adọba ụgbọala mbụ, ọkọnọ ahụ na-eche ahịa ihu site na nkwado ụfọdụ, ọnụego mmepụta PDH nke mba ahụ dịkwa 69.79% dịka ụbọchị 14, nke dị 0.2% ala karịa okirikiri gara aga. Ka owuwu propylene dara, ngwa ahịa mmepụta propylene adịghị elu n'ozuzu ya, a na-ebuli ọnụ ahịa onyinye ahụ nwayọ nwayọ, ịnụ ọkụ n'obi ịzụta ihe ka mma, ikuku azụmaahịa zuru oke dịkwa mma.

N'ime usoro a, usoro atọ nke propylene na-agwakọta, uru nke propane dehydrogenation na propylene pụtara ìhè karịa. N'otu aka, ọnụahịa propane na-aga n'ihu na-ada n'oge a, n'aka nke ọzọ, ọnụahịa propylene monomer siri ike, nke na-eme ka uru ahụ dịkwuo elu. Uru nke naphtha na methanol na propylene nọgidere na-ada, uru nke usoro methanol na propylene belatara nke ukwuu, nke bụ isi metụtara mmụba ọnụ ahịa nke methanol ihe eji emepụta ihe, nke gbochiri uru ahụ. Uru usoro Naphtha na propylene na-adakarị site na izu gara aga, isi ihe na-emetụta bụ na ọnụahịa naphtha na-ebelata elu, mana na uru na-akpata, a na-atụ anya na ọ ga-eme ka mgbanwe uru propylene dị mkpụmkpụ, lebara anya nke ọma na ọnụ ahịa ahịa nke ihe eji emepụta ihe.

N'oge na-adịghị anya, n'akụkụ ọkọnọ, site na mmalite nke ngwaọrụ PDH na Shandong, ibu nke mmepụta ọhụrụ a na-etinye na mbido na-abawanye nwayọ nwayọ, a na-atụkwa anya na ọkọnọ propylene ga-abawanye, mana ebe a na-adọba ụgbọala nwa oge nke ngwaọrụ ụlọ ọrụ nke ọ bụla na Shandong ga-enye aka n'ahịa ahụ.
