I-Butadiene: Ipateni yokuqinisa iqhubekile rhoqo

Ukungena kwi-2023, imakethi ye-butadiene yasekhaya iphakame kakhulu, ixabiso lentengiso linyuke nge-22.71%, ukukhula kweminyaka engama-44.76%, kufezekisa isiqalo esihle. Abathathi-nxaxheba kwimakethi bakholelwa ukuba iphethini yentengiso ye-Butadnene ye-2023 iya kuqhubeka, imakethi ifanelekile ukukhangela ixesha lokuphumla kwendawo yendawo yokuhlala yasekhaya okanye iya kuba ngaphezulu kwe-2022, ukusebenza kakhulu.

Ukuguquguquka kwemakethi ephezulu

UJin Lianchuang Uhlalutyo lwe-Nhang Xhang Xiuping uthe le shishini libe lifikile malunga nemakethi ye-butadiene ngoJanuwari ngenxa yempembelelo yokuveliswa kwemveliso ye-Shenghong kunye neShemical. Nangona kunjalo, ulondolozo olulindelekileyo lwezityalo zebhadiene eZhejiang Potrochemical noZhenhai kunye neMichiza yeKhemikhali ngoFebruwari nangoMatshi ziye zaphakamisa umoya wentengiso. Ukongeza, uTianchen Qiixiang noZhejiang Perochemical Co., ltd. 'I-acrylonitile-i-butadiene - i-styrene copolymer (ABS) iyanda. Imakethi iphonononge ngokubanzi.

Nangona iyunithi yebhadiene kwiSigaba se-II ye-II ye-ITejiang Petrochemical icwangciselwe ukulondolozwa kolondolozo phakathi kwe-FEBRUWARI, kunye nesityalo se-Zhenhai kunye nesityalo se-hainan kunye nesityalo sekhemikhali kunye nepetrochina Isityalo se-guangdong sicwangciselwe ukuba sisebenze ngoFebruwari. Phantsi kwempembelelo ebanzi, ukunqongophala kwebhadiene kulindeleke ukuba kuzinze kodwa kungabi namandla, kwaye ixabiso lentengiso kulindeleke ukuba lihlale liphezulu.

Ukusuka kwimbono yokukhutshwa komthamo weBifuenene ngo-2023, kunokubakho iitoni ezizigidi ezili-1,04 ezikhutshelweyo ezikhutshwe unyaka wonke, kodwa ukulibaziseka kwezinye iindlela ezingenakugwetywa. Kwangelo xesha, uninzi lwezityalo ezitsha ebezimele ukuba zisebenze ekupheleni konyaka ophelileyo ziye zalibaziseka kwisiqingatha sokuqala salo nyaka. Ukongeza kwi-Shenghong ecocekileyo kunye nemichiza, ezinye izityalo ze-butadiene ezifana ne-dongmical petrochemicalical ikwanokusebenza. Kwisiqingatha sokuqala salo nyaka, esichaphazeleka kukukhululwa kobume obutsha bokuvelisa, ukuhanjiswa kwe-butadiene kuya kuyichitha ngokuthe ngcembe, imakethi okanye ibonise indlela yokuvula eqaqambileyo.

Kulindelwe ukuba inani eliqingqiweyo lezixhobo zebhadiene ezintsha ziya kufakwa kwimveliso kwisiqingatha sesibini sonyaka, kwaye kulindeleke ukuba izixhobo ezintsha zokuhlala zisezantsi ziya kufakwa kwimveliso. Ukunyuka kwemfuno kuya kuba nkulu kunokunyusa ukubonelela, kunye nemeko yemakethi eqinileyo iya kuqhubeka.

Ukongeza, kunye nohlengahlengiso lomgaqo-nkqubo wobukrelekrele kunye nokulindelwa kokuchacha koqoqosho, imfuno yesiphelo sendlela yekhaya kwisiqingatha sesibini sonyaka inokuphuculwa xa kuthelekiswa nesiqingatha sokuqala sonyaka, kunye nenkxaso yamaxabiso kwi I-Caenti Cade iyaphuculwa xa kuthelekiswa nesiqingatha sokuqala sonyaka. Ugxininiso lwexabiso elipheleleyo lebhadiene njengezixhobo eziluhlaza zingaphezulu kwesiqingatha sokuqala sonyaka.

Ixabiso lezinto ezingafunekiyo kunzima ukuwa

Njengesityebi se-Pumpstone, njengezixhobo ze-butadiene, ixhaswe kukukhula kwemfuno ngo-2022, kwaye ukuveliswa kwe-oyile yengqondo yelitye iqhubekile ukhula unyaka wonke. Ngokwedatha evela kwi-Bureau kaZwelonke yeenkcukacha-manani, ukukhutshwa kweoli yeBongo yeLizwe kwilizwe lam ngonyaka wam ngo-2022 yayingama-54.78 yezigidi zeetoni, ukunyuka kwe-10.51% kunyaka ophelileyo; Umthamo wokungenisa i-Wibfit Brain yayiyi-9,26 yezigidi zeetoni, kwaye ukusetyenziswa kwe-Grain Grain Grail Bike yayiyi-63.99 yezigidi zeetoni zokusetyenziswa kwe-63.99 yezigidi zeetoni. , Inyuke nge-13.21% kunyaka ophelileyo.

Ngowama-2023, ngokulala kancinci kobhubhane, umgaqo-nkqubo ulungile, uqoqosho ngokuthe ngcembe, iqondo lokusebenza elihamba kancinci, ishishini le-petroleam leoli liya kunyuka. Kulindelwe ukuba le meko kulindeleke ukuba iqhubeke kude kube yikota yesithathu. Ngekota yesine, i-terrochemical terminal ingenise ukusetyenziswa kwemveli, isazi sobuso, kunye nolwakhiwo lomhlaba ezantsi. Ibango le-petroleum kunye neoyile yayinomngcipheko wokwehla.

Kuzo zonke, xa i-Recinery ingenise ixesha lokulungiswa eliphakathi kwikota yesibini, ukuhanjiswa kweoli yepetroleum kuncitshisiwe kwaye kuxhaswe kwakhona imarike. Nangona kunjalo, ngenxa yokuthoba ukhula loqoqosho lwehlabathi kunye nemfuno engonelanga, irebound ilinganiselwe, kwaye ixabiso linokuqhubeka nokulungiswa emva kokuba ixabiso liphezulu. Ikota yesithathu yayiyincopho yokuhamba ngokwemvelo. Okwangoku, amaxabiso e-oyile ahlabayo ahamba kancinci abuyele kuluhlu olusengqiqweni. Inzuzo yesixhobo sokuqhekeka esiphuculweyo, umsebenzi wentengiso unyukile, kwaye iindleko zezinto ezingafunekiyo zazigudileyo kwi-Dowream. Kwikota yesine, imakethi yepetrochemical iya kungena ekusetyenzisweni kwendabuko, ingcinga, ibango liye lahla, kwaye ixabiso lengqondo yelitye liya kuwa kwakhona.

Ukusuka kwimbono yoshishino lokucoca, ukwakhiwa okukhawulezileyo kweprojekthi yokuhlaziya i-Yulong Island kucetywa ukuba ifakwe kwimveliso ekupheleni kwe-2023. Isigaba sesibini se-hainan petinesical hainan kunye ne-Zhenhai iSicwangciso sePerooc igxile kwi-2023 ukuya kwi-2024. Ukukhula kwezixhobo zeoyile zeoyile ngokungathandabuzekiyo kuyingenelo kwimakethi yeoyile, ngoko ke ixhasa downwinard of Dowstream kubandakanya i-butadiene ngokweendleko.

Ukunyuka kwemfuno ye-dowwream

Ukufaka i-2023, impembelelo yemigaqo-nkqubo ethandekayo njengerhafu yokuthenga ye-Butadiene iphuculwe kancinane, kwaye ishishini lerabha yerabha yayilungiselelwe ngenkuthalo. Kwangelo xesha, ukuphuculwa okuqhubekayo kothintelo loThintelo lweSizwe lweSizwe nalo kuzisa izibonelelo kwimarike yerabha. Ukunyusa ibango elikhanyayo ngexesha leholide yentwasahlobo, kunye nendawo ekhulayo ye-Dowstream ye-Butadiene, kulindeleke ukuba ihambele kwintengiso yase-2023, kwaye ibala le-butadigene liya kwanda kakhulu.

Ukusuka kwimbono yokukhutshwa komthamo kwi-2023, amandla eButadieBenBenBenBenBenBenBenBenBenBenBenBenBenBenBenBenBenBenBenblebnBenblebnBenBenblebnBenblebnBenbnub inomthamo ophantsi, oneminyaka engama-40,000 kuphela; I-capsule entsha yecapsule ineetoni ezingama-273,000; I-Polypropylene kunye neChiunyrene -butadiene -llyrene Covergence Imakethi yeMveliso yeMveliso yi-150,000 yeetoni / ngonyaka; I-ABS iyongeze i-444,900 yeetoni / ngonyaka, kunye nokwanda kwemveliso yemveliso ye-tintog yi-50 000 yeetoni / ngonyaka; Akunzima ukubona ukuba isixhobo esitsha sihlala sifaka imveliso, kwaye imfuno esezantsi kulindeleke ukuba inyuke kakhulu. Ukuba isikhundla semveliso esingentla sikhutshwe ngexesha, ngokungathandabuzekiyo sisibonelelo esikhulu kwimarike yebhadiene.

Ukongeza, njengoko imigaqo-nkqubo yothintelo ekhoyo ngoku iyaqhubeka ifanelekile, ifuthe lezinto ezizahliweyo kwizinto eziphathekayo nokuthumela ngaphandle ziya kumenza buthathaka kwixesha elizayo. Ndijonge phambili kwi-2023, i-Butadiene Inqanaba lokuzimisela iya kuqhubeka, ngokungenisa ivolumu iya kuqhubeka nokwenza umthambo, kodwa ukubuyiselwa kwemfuno yelinye ilizwe kuya kunceda i-Butadiene Puby Counter Poyundi. Ukwenzela ukuba ilungelelanise ubonelelo lweentengiso zasekhaya kunye nephethini yemfuno, ukwanda komhlaba yokuthengiswa kwabantu kunokuba yinjongo yamashishini okuvelisa i-butadiene yasekhaya.
