Sanadihii la soo dhaafay, sida technology bislaaday iyo wanaajinta joogtada ah ee qoondaynta suuqa, petrochemical warshadaha, olefin joogo isbeddel horumarinta kala duwan ee alaabta ceeriin, gaar ahaan ka hooseeya asalka ah ee carbon double, a weyn Bob propane news la xiriira, waa awoodda rabitaanka Leon, iyo Saliida dhaqameed ee olefin / dhuxusha ilaa olefin / methanol ilaa olefins, habka fuuq-baxa propane ee wax-soo-saarka propylene wuxuu ahaa mid sarreeya. hydrogenproduct-product, isha kaliya ee alaabta ceeriin waxaa lagu hayn karaa oo kaliya wax soo saarka polypropylene ee alaabta guud, iyadoo imaatinka wareegga cusub ee wareegga ballaarinta ee polypropylene ka dhigaysa sii kordheysa muujinaya ismaandhaaf qaabdhismeedka u dhexeeya sahayda iyo baahida, horumarinta polypropylene-dhamaadka sare noqday Habka ugu muhiimsan ee tartanka kala duwan, wareegaan tartanka, propane dehydrogenation PP tartanka farsamada PP ayaa bilaabay inuu hoos u dhaco, inkastoo ay jirto qayb ka mid ah ganacsiga Si kastaba ha ahaatee, la'aanta ethylene ayaa noqotay guddiga gaaban ee habka PDH.Dhanka kale, Shiinuhu waxaa ka maqan kheyraad ku habboon awoodda sahayda ee hydrocarbon-ka fudud kuma filna.Inta badan khayraadka alaabta ceeriin waxay u baahan yihiin in la soo dhoofiyo, markaa xasiloonida sahayda alaabta ceeriin waxay noqotaa furaha horumarinta habka hydrocarbon-ka fudud Laga bilaabo 2014 ilaa 2018, mashruuca caadiga ah wuxuu ahaa propane dehydrogenation.Si kastaba ha ahaatee, tan iyo 2018, caanka ah ee dildilaaca hydrocarbon iftiinka ayaa si degdeg ah u kacay sababtoo ah dabacsanaan xoog leh iyo ductility.Qaar ka mid ah mashaariicda tijaabada ah ayaa la soo saaray 2020.

Wax-soosaarka ethylene ee ethane, propane iyo butane dildilaaca waa sarreeyaa.Shirkadaha ka faa'iidaysiga dhammaystiran ee hydrocarbon-ka fudud, wax-soo-saarka ethylene ayaa saamayn muuqata ku leh wax-soo-saarka kiimikaad ee hoose, iyo xulashada dariiqa hoose waxay leedahay dabacsanaan sare iyo meel doorasho.Habka leh wax-soo-saarka propylene sare waa PDH MTP C/MTO, laakiin badeecada la beegsanayo ee dildilaaca hydrocarbon iftiinku waxay leedahay wax-soosaar sare waxayna sidoo kale soo saari kartaa hydrogen nadiif ah oo ka soo baxa, kaas oo loo tixgeliyey mid ka mid ah siyaabaha muhiimka ah ee lagu dhimayo. ku tiirsanaanta batroolka iyo isticmaalka tamarta warshadaha.Sidaa daraadeed, kobcinta horumarinta mashaariicda qashinka korontada ee gudaha ayaa ah mid aad u degdeg ah, iyo ciyaartoy badan oo cusub oo aan awood u lahayn inay ku shaqeeyaan saliidda cayriin ayaa sidoo kale soo galay horumarinta joogtada ah ee alaabta ceeriin, siyaabaha lagu helo propylene ayaa sii kordhaya.Ka dib fuuq-baxa propane, mashruucyada dildilaaca kaarboon-carbon ayaa si tartiib tartiib ah u kordhaya.Propane kaliya maaha alaabta ceeriin ee fuuqbaxa si ay u soo saarto propylene, laakiin sidoo kale alaabta ceeriin ee ugu muhiimsan ee dildilaaca hydrocarbon fudud si loo soo saaro propylene.Waa maxay faraqa u dhexeeya qaab dhismeedka alaabta ee u dhexeeya fuuq-baxa propane iyo dildilaaca hydrocarbon fudud?Nidaamkee ayaa noqon doona mid aad u tartan badan xarumaha wax soo saarka mustaqbalka?Kor u kaca propane sida tignoolajiyada wax soo saarka ugu weyn ee Propylene yaraanta dalkeena, ku-xigeenka dhaqameed ee wax soo saarka propylene ma dabooli karo baahida sii kordheysa ee soosaarayaasha propylene gudaha, isla mar ahaantaana, horumarinta gaaska shale ee Bariga Dhexe iyo Waqooyiga Ameerika ayaa ka dhigaya wax soo saarka propane. kor u kaca dhoofinta dhoofinta koror weyn, kor u kaca tikniyoolajiyada propane ee gudaha waxay bixisaa agab cayriin oo ku filan si ay u taageeraan Habka ansixinta fudud Saamaynta maalgashiga gaaban iyo degdegga ah ee mashaariicda fuuq-baxa propane waxay keentay fursado horumarinta dhaqaalaha ee xeebaha Shiinaha.Fuuqbaxa Propane iyo mashaariicda fuuqbaxa alkane ee isku dhafan ayaa ku soo badanaya Shiinaha.Habka soo saarista olefin iyadoo la jajabinayo hydrocarbon fudud sida alaabta ceeriin ay kor u kacayso Hal ama laba nooc oo butane ah) iyadoo alaabta ceeriin ee dildilaaca shirkadaha olefin ay si tartiib tartiib ah u korodhay, sida Boralidek Basle Petrochemical Xinpu kiimikaad Huatai Shengfu iyo laba nooc oo kale oo ah habka wax soo saarka Propane fuuqbaxa, sida hab cusub oo lagu soo saaro propylene ka propane sida hal shay oo ceyriin ah, waxay soo saartaa propylene ka badan pyrolysis uumiga hydrocarbon iftiinka, laakiin sidoo kale waxaa jira dhibaatooyin heerka beddelka hal-jid hooseeya iyo shuruudaha sare ee alaabta ceeriin.Wax-soo-saarka propylene ee geedku wuxuu gaari karaa in ka badan 80%, kaas oo keeni kara xaddi badan oo alaabta ceyriin ah oo loogu talagalay propylene hoos-tagga qulqulka iftiinka hydrocarbon ma hagaajin karo oo kaliya saamiga wax-soosaarka propylene/ethylene ee unugga, laakiin sidoo kale si buuxda u isticmaali kara khayraadka sifaynta, taas oo ah jihada horumarinta ee ka kooban alaabta ceeriin ee cutubka dildilaaca.Marka la eego xaaladda wareegga buuxa ee propane, dhalidda diene ee habka dildilaaca hydrocarbon fudud waxay gaari kartaa in ka badan 60%, iyo alaabooyinka la soo saaro ayaa aad uga badan fuuq-baxa propane

Propane dehydrogenation alternaria alternata propylene by-product hydrogen gaaska, haddii hydrogen by-product oo aan channels iibka, kaliya gubi karaa sida gaaska shidaalka, si toos ah u saameyn doonaa dhaqaalaha ee fuuqbaxa propane, marka la barbar dhigo dildilaaca hydrocarbon iftiinka, propane dehydrogenation (hydrogen gubanaya) Halbeegga olefin wuxuu ka sarreeyaa habka fuuq-baxa propane, alaabada ugu muhiimsan ee dildilaaca hydrocarbon ee ethylene propylene, badeecada hydrogen gaaska isku dhafka ah ee kaarboon afar isku dhafan oo shan ah, waxay xallin kartaa fuuq-baxa propane lafteeda iyada oo aan ethylene iyo butene qoomameyn, pyrolysis of wax soo saarka ayaa mar kale ogaan kara qiimaha iyaga u gaar ah, isla mar ahaantaana waxay leedahay faa'iidada qiimaha jaban, waxay ku jiri kartaa suuqa copolymerization aan sharciyeysneyn iyo saameyn ku yeelashada copolymerization, dhaqaale badan sanadihii ugu dambeeyay Warshadaha tamarta hydrogen waxay leedahay siyaasad xoog leh oo wadista .Isla mar ahaantaana, korodhka tirada xaaladaha codsiga terminal, dhinaca baahida suuqa ayaa sidoo kale si tartiib tartiib ah kor u qaaday warshadaha tamarta hydrogen ilaa xad, iyo inta badan shirkadaha propane ee gudaha ayaa bilaabay in ay fiiro gaar ah ama xitaa qaabeynta. kanaalka iibka ee iyaga u gaar ah iyo qorshayaasha ka faa'iidaysiga ee hydrogen by alaabta Xaaladdan oo kale, fuuqbaxa propane, haddii lagu iibiyo sida hydrogen hydrogen ama sida ka qaalisan unugyada shidaalka hydrogen ama xataa daahirsanaan sare, waxay bixin doontaa soo celin dhaqaale oo sidaas kor u faa'iidada shirkadaha propane fuuqbaxa. .Marka la barbardhigo, tignoolajiyada fuuq-baxa propane waxay leedahay geeddi-socod gaaban iyo isticmaalka hooseeya Wax-soo-saarka sarreeya iyo kharashka maalgashiga hooseeya ee hal qalab.Haddii lagu dari karo qalabyada sifaynta ee ku hareeraysan si loo bixiyo hydrogen si loo sifeeyo oo loo kordhiyo faa'iidooyinka iyada oo loo marayo sahayda wadajirka ah ee alaabta ceeriin, faa'iidada qulqulka hydrocarbon iftiinku waxay ku jirtaa qiyaasta maalgashiga ballaaran, noocyo kala duwan oo alaab ah iyo awood xooggan oo looga hortagayo khatarta suuqa.Dhaqaalaha labada inta badan wuxuu ku xiran yahay ethylene iyo qiimaha Propylene: Dariiqa fuuq-baxa propane waa ka dhaqaale badan yahay marka qiimaha ethylene iyo propylene ay dhow yihiin, dariiqa dillaaca hydrocarbon-ka fudud ayaa ka dhaqaale badan marka qiimaha ethylene uu ka sarreeyo propylene.

Propane fuuqbaxa alaabta ceeriin hal, oo kaliya isticmaalaya propane sida alaabta ceeriin, wax soo saarka kaliya propylene iyo hydrogen by-product, ilaalinta deegaanka kaarboon hooseeyo ma aha oo kaliya, weli waa la dhimi karaa khataraha arrimo kale, weli waa cusub hadda galay doorashada ugu weyn ee farsamada ee ganacsiga. Inta badan ee wax soo saarka Shiinaha ee qalabka PDH u dhigma qalab hoose, isdhexgalka warshadaha iska cad, laakiin mustaqbalka fog, booska horumarinta silsilad warshadaha hoose waa cidhiidhi, Cadaadis Market waa weyn, in awoodda wax soo saarka polypropylene gudaha labanlaaban tartanka suuqa ba'an. Mashruuca fuuq-baxa ethylene propane tartankiisa ayaa mudan in dib loo qiimeeyo.

Marka la barbar dhigo fuuq-baxa propane, habka dildilaaca hydrogen kaarboon fudud ayaa leh xalal kala duwan oo badeecado ah iyo saameyn xoogan oo suuqa ah.Marka la barbardhigo, dhaqaalaha geeddi-socodka fuuq-baxa propane wuxuu inta badan ku xiran yahay farqiga qiimaha u dhexeeya propylene iyo propane.Marka qiimaha suuqa ee propylene isbedbedesho oo hoos u dhaco, dhaqaalaha habka fuuqbaxa propane si weyn ayaa loo dhimi doonaa.

Warshadaha polypropylene, isha propane waxay ku xisaabtamaysaa qayb yar, inkasta oo ay ka korodhay 7% 2015 ilaa 15% 2022, weli kuma mashquulin suuqa caadiga ah waxayna leedahay xuquuq daciif ah oo lagu qiimeeyo alaabta polypropylene.Si kastaba ha ahaatee, iyada oo horumarinta joogtada ah ee tamarta khafiifka ah iyo alaabta ceeriin kiimikada ee Shiinaha, isbeddelka kala-duwanaanta ee ilaha saliidda cayriin ee polypropylene ayaa soo jeestay, iyo soo bixitaanka xilligii "propane", kama fogaan doono naphtha, propane iyo dhuxusha. waxa loo qaybin doonaa sadex qaybood oo aduunka ah.
