I-PTA ayinuki kamnandi? Iinkunzi ezininzi ngokulandelelana "ziphuma kwisangqa", kwenzeke ntoni?
Qhaqha! Ineos, Rakuten, Mitsubishi baphuma kwishishini le-PTA!
IMitsubishi Chemical: Ngomhla wama-22 kuDisemba, iMitsubishi Chemical yabhengeza iindaba ezininzi ngokulandelelana, kuquka isibhengezo sokudluliswa okucwangcisiweyo kwe-80% yezabelo zenkampani yayo engaphantsi kwe-Indonesia kunye nokuqeshwa kwabasebenzi abaphezulu njenge-CEO entsha.
Kwintlanganiso yabaphathi ebibanjwe ngomhla wama-22, iMitsubishi Chemical Group igqibe ekubeni idlulisele i-80% yezabelo zayo kwiMitsubishi Chemical Corporation (PTMitsubishi Chemical lndonesia) yase-Indonesia kwi-PT Lintas Citra Pratama. Le yokugqibela isebenza kwishishini le-pure terephthalic acid (PTA).
I-MCCI ibisenza kwaye ithengisa iiPtas e-Indonesia ukusukela oko yasungulwa ngo-1991. Nangona imakethi ye-PTA kunye neshishini e-Indonesia zizinzile kwaye ziqinile, iQela liyaqhubeka nokuqwalasela indlela eliya kuyo ishishini ngelixa liqhubela phambili ulawulo lwepotifoliyo yalo ligxile ekukhuleni kwemakethi, ukhuphiswano kunye nokuzinza ngokuhambelana nendlela yalo yeshishini ethi "Yakha Ikamva".
Isebe eliphantsi kwe-PT Lintas CitraPratama liceba ukwenza i-paraxylene, eyona nto iphambili ekrwada ye-PTA, ithengiswe kuMzantsi-mpuma we-Asia.
Ngaphambili, izinto ezintsha zekhemikhali bezixela ukuba iinkampani ezinkulu zamazwe ngamazwe eziquka i-Ineos kunye ne-Lotte Chemical zivale/zirhoxile kwiiprojekthi ze-PTA.
I-Lotte Chemical ibhengeze ukuba: ishiya ngokupheleleyo ishishini le-PTA
I-Lotte Chemical ibhengeze ukuba iceba ukuthengisa isabelo sayo se-75.01% kwi-Lotte Chemical Pakistan Limited (LCPL) kwaye iphume ngokupheleleyo kwishishini le-refined terephthalic acid (PTA). Olu lwabiwo-mali luyinxalenye yesicwangciso sexesha eliphakathi se-Lotte Chemical sokuqinisa ishishini layo lezinto ezikhethekileyo ezinexabiso eliphezulu.
Ikwindawo yasePort Qasim, eKarachi, iLCPL ivelisa iitoni ezingama-500,000 zePTA ngonyaka. Le nkampani ithengise eli shishini kwiLucky Core Industries (LCI), inkampani yeekhemikhali yasePakistan, nge-19.2 yeebhiliyoni zeewon (malunga ne-1.06 yeebhiliyoni zeeyuan) (iLotte Chemical ithenge iLCPL nge-14.7 yeebhiliyoni zeewon ngo-2009). I-LCI ikakhulu ivelisa i-PTA derivative polyester, ivelisa iitoni ezili-122,000 zepolyester polymer kunye neetoni ezili-135,000 zepolyester fiber ngonyaka eLahore, ngelixa iitoni ezingama-225,000 zesoda ash ngonyaka eHeura.
ULotte Chemical uthe imali efunyenwe kwintengiso yeshishini le-PTA iza kusetyenziselwa ukuphuhlisa imakethi ekhoyo yeemveliso ezinexabiso eliphezulu ezifana ne-polyethylene, i-polypropylene kunye ne-polyethylene terephthalate, kunye nokwandisa ishishini leekhemikhali ezikhethekileyo kunye nokungena kwishishini lezinto zokusingqongileyo.
NgoJulayi 2020, iLotte Chemical yayeka ukuvelisa i-PTA kwisityalo sayo esivelisa iitoni ezingama-600,000 ngonyaka e-Ulsan, eMzantsi Korea, yaza yasiguqula saba yindawo yokuvelisa i-fine isophanic acid (PIA), okwangoku enomthamo we-PIA weetoni ezingama-520,000 ngonyaka.
U-Ineos: Ubhengeze ukuvalwa kweyunithi ye-PTA
Ngomhla wama-29 kweyeNkanga, u-Ineos wabhengeza ukuba uceba ukuvala iiyunithi ezimbini ze-PTA (i-refined terephthalic acid) ezincinci nezindala kwiziko layo lemveliso elihlanganisiweyo le-PX kunye ne-PTA kumzi-mveliso walo eHerr, e-Antwerp, eBelgium.
Le yunithi ibingasebenzi ukususela ngo-2022 kwaye uphononongo lwamathemba ayo exesha elide beluqhubeka kangangexesha elithile.
U-Ineos uthe kwingxelo yakhe kawonke-wonke ukuba izizathu eziphambili zokuvalwa kwesi sityalo zezi: ukwanda kwamandla, izinto eziluhlaza kunye neendleko zabasebenzi kwenza imveliso yaseYurophu ingakhuphisani kangako nokuthunyelwa kwe-PTA entsha kunye nomthamo ophumayo e-Asia; Kwaye eli qela lifuna ukugxila ngakumbi kwizinto ezintsha ezikumgangatho ophezulu.
Imveliso engaqhelekanga yezinto ezikrwada, imfuno ephantsi "ye-0"?
Xa sijonga imakethi yasekhaya ye-PTA, okwangoku, ixabiso eliqhelekileyo le-PTA ngonyaka ngo-2023 liye lehla xa lithelekiswa nowama-2022.
Nangona ingxaki yakutshanje yoLwandle oluBomvu kunye nokuvalwa kwengingqi yasekhaya okubangelwe yimozulu ebandayo, i-PTA inyukile; Nangona kunjalo, ukuphela kokuphela kwee-odolo zelaphu akukuhle, ukusonta okusezantsi, amashishini okuluka awanakho ukuzithemba kwimarike yexesha elizayo, kwimeko yokwanda kwempahla yawo kunye noxinzelelo lwezemali kwixabiso eliphezulu lokumelana nezinto ezikrwada kunamandla, okubangela ukuba iintlobo zepolyester zibe nzima ukuzitsala, okubangela ukuba inqanaba lenzuzo yeentlobo zepolyester lihle kakhulu.
Ukongeza, ngophuhliso olukhawulezileyo lweeprojekthi zokudibanisa, amandla e-PTA yexesha elizayo asabonisa umkhwa okhulayo. Ngo-2024, kulindeleke ukuba i-PTA yasekhaya ivelise iitoni ezili-12.2 lezigidi, kwaye izinga lokukhula kwamandla e-PTA linokufikelela kwi-15%, ngokombono wamandla emveliso, i-PTA inokujongana noxinzelelo olukhulu.
Kwiminyaka yakutshanje, ishishini le-PTA lasekhaya liye lafumana ixesha lomthamo ogqithisileyo kunye nokutshintshwa komthamo, utshintsho kwindlela yokubonelela lunempembelelo enkulu kwimarike, kunye nezixhobo ezintsha eziqalisiweyo, imeko yexesha elizayo yokubonelela ngokugqithisileyo kwishishini le-PTA lasekhaya okanye imeko enzima ngakumbi.
Ukukhawulezisa ukususwa! Eli shishini liya lisiba likhuphisana ngakumbi
Ngokuveliswa kothotho lwezixhobo ezinkulu ze-PTA, amandla e-PTA ngokubanzi abe makhulu kakhulu, kwaye ukhuphiswano kushishino luye lwaba lubi kakhulu.
Okwangoku, amashishini aphambili e-PTA ayaqhubeka nokunciphisa iifizi zokucubungula, athathe isabelo semarike, asuse amandla okuvelisa angasemva, uninzi lwezixhobo ezineendleko eziphezulu zokucubungula zisusiwe, kwaye kwiminyaka yakutshanje, izixhobo ze-PTA ezisandula ukufakwa kwimveliso zingaphezulu kweetoni ezi-2 zezigidi zezixhobo eziphambili kwiifektri ezinkulu, kwaye iindleko zokucubungula eziphakathi zoshishino zinciphile kakhulu. Kwixesha elizayo, amandla okuvelisa aphambili aya kwanda, kwaye iindleko zokucubungula eziphakathi zesixhobo sangaphakathi soshishino ukuvelisa i-PTA ziya kuncipha ngemveliso, kwaye umrhumo wokucubungula uya kuba kwinqanaba eliphantsi ixesha elide.
Ngoko ke, kwimeko yokuthengiswa kakhulu, ukhuphiswano olukhulayo kushishino, kunye nokuncipha kwenzuzo, ukusinda kweenkampani ngokungathandabuzekiyo kunzima, ngoko ke kubonakala ngathi ukhetho lwe-Ineos, Rakuten, Mitsubishi nalo lufanelekile, nokuba kukugxila kwishishini eliphambili ukuze kuhluthwe amashishini, okanye kukwaphulwa kwezixhobo ukuze kusindiswe, okanye kukulungiselela amaqhinga alandelayo okuwela imida kunye namanye amaqhinga.
