[Hagaha] : Dabayaaqadii Juun, xidhitaanka lama filaanka ah ee qalabka suuqa propylene ayaa dhacay midba midka kale, kaas oo ku habboon dhinaca sahayda, halka xamaasadda badeecadaha hoose ay kor u kacday, qiimaha suuquna uu istaagay hoos u dhaca, laga bilaabo Luulyo 14, oo ah heerka caadiga ah. wax kala iibsiga qiimaha suuqa Shandong propylene waxa uu ahaa 6480-6500 yuan/ton, wax kala iibsiga guud ee suuqa Bariga Shiinahana waxa uu ahaa 6350-6350 yuan/ton.

Wareeggan, suuqa propylene ee gudaha ayaa joojiyay hoos u dhaca iyo soo kabashada, iyo arrimaha taageeraya dib u soo kabashada suuqa ayaa inta badan ku jira aasaaska sahayda iyo baahida. Macro, qiimaha saliidda caalamiga ah ayaa kor u kacay, arrimaha ugu muhiimsan ee wanaagsan ayaa ah: xogta sicir-bararka ee Maraykanku waa wanaagsan tahay, Kaydka Federaalka si uu u sii wado kor u qaadista cadaadiska dulsaarka ayaa daciifay, iyo dhimista wax soo saarka dheeraadka ah ee Sacuudi Carabiya waxay keentay sii wadida jawiga wanaagsan, suuqa. Isla mar ahaantaana, baarkinka ku meel gaadhka ah ee Qingdao Jinneng, Wangtong, iyo aaladaha Zhenghe propylene ee gobolka, halka aaladda dayactirka baarkinka hore aan dib loo bilaabin, sahayduna waxay soo food saartay suuqa oo leh taageero gaar ah, iyo heerka wax soo saarka PDH ee qaranka waa 69.79% marka loo eego 14 maalmood, taas oo 0.2% ka hooseysa wareeggii hore. Dhicistii dhismaha propylene, alaabada shirkadaha wax soo saarka propylene maaha mid sarreeya guud ahaan, qiimaha wax-soo-saarka ayaa si tartiib tartiib ah kor loogu qaadayaa, xamaasadda wax iibsiga ee hoose ayaa ka sii wanaagsan, jawiga ganacsigu waa OK.

Wareeggan, saddexda hab ee propylene ayaa isku dhafan, iyo faa'iidada fuuq-baxa propane ee propylene ayaa aad u muuqda. Dhinaca kale, qiimaha booska propane ayaa sii wadi doona inuu hoos u dhaco marxaladan, iyo dhinaca kale, qiimaha propylene monomer waa mid xoogan, taas oo siinaya kor u kaca qiimaha faa'iidada. Faa'iidada nafta iyo methanol ee propylene ayaa sii waday inay hoos u dhacdo, iyo faa'iidada methanol ee habka propylene ayaa si weyn hoos ugu dhacday, taas oo inta badan ay saamaysay qiimaha kor u kaca ee methanol alaabta ceeriin, taas oo caqabad ku ah faa'iidada. Naphtha ilaa propylene habka faa'iidada waxay u egtahay in ay hoos u dhacdo usbuucii hore, qodobka ugu muhiimsan ee saameynaya waa qiimaha naphtha ee kor u kaca, laakiin sidoo kale faa'iidada wadista faa'iidada keentay, ayaa la filayaa in muddada gaaban ee isbeddelka faa'iidada propylene, goor dambe fiiro gaar ah u yeelato suuqa qiimaha alaabta ceeriin.

Muddada gaaban, dhinaca sahayda, iyada oo dib loo bilaabo qalabka PDH ee Shandong, culeyska cusub ee la geliyey wax soo saarka marxaladda hore ayaa si tartiib tartiib ah u kordhay, iyo sahayda hadda jirta ee propylene ayaa la filayaa in ay kordho, laakiin baarkin ku meel gaar ah Aaladaha warshadaha gaarka ah ee Shandong waxay siin doonaan xoogaa kor u kaca suuqa. Dhanka baahida, marxaladan, suuqa polypropylene wuxuu u muuqdaa inuu noqdo isbeddel xooggan, faa'iidada budada waa OK, warshadaha hoose waxay u baahan yihiin inay iibsadaan inta badan, halka toddobaadka soo socda PO, warshadda acrylonitrile la filayo inay dib u bilowdo, waxaa la filayaa in propylene-ga gaaban. suuqa ayaa laga yaabaa inuu yeesho koror yar, laakiin booska kaca ayaa xaddidan, si dhow ula soco dib u bilaabashada iyo soo dejinta soo-saareyaasha propylene.

Dhinaca dalabka, isbeddelka suuqa polypropylene ee wareegga, taageerada dhinaca baahida waa mid xooggan, qiimaha hore ee propylene ayaa hoos u dhacay, faafitaanka u dhexeeya propylene iyo PP ayaa kordhay, faa'iidada warshadda hoose ayaa si tartiib tartiib ah u korodhay, xamaasadda wax iibsiga ayaa sidoo kale si tartiib tartiib ah loo soo qaatay. kor u kacday, taasoo keentay in si habsami leh loo raro shirkadaha propylene, booska alaabada si tartiib tartiib ah hoos ugu dhaco, taageerto qiimaha propylene.
