Los ntawm 2019 txog 2023, qhov nruab nrab txhua xyoo kev loj hlob ntawm PVC muaj peev xwm yog 1.95%, thiab lub peev xwm ntau lawm tau nce los ntawm 25.08 lab tons hauv 2019 mus rau 27.92 lab tons hauv 2023. Ua ntej 2021, cov ntshuam dependence tau ib txwm nyob ib ncig ntawm 4%, feem ntau. vim tus nqi qis ntawm cov peev txheej txawv teb chaws thiab qhov nyuaj ntawm kev hloov qee cov khoom siv high-end.

Lub sijhawm peb xyoos ntawm 2021-2023, PVC muaj peev xwm ntau lawm tau nce, thaum kev xa khoom kuj nce nrawm, vim qee qhov khoom siv txawv teb chaws raug cuam tshuam los ntawm kev quab yuam majeure, cov khoom raug cuam tshuam, thiab tus nqi tsis muaj kev sib tw kom zoo dua, thiab cov ntshuam dependence poob rau. tsawg dua 2%. Nyob rau tib lub sijhawm, txij li xyoo 2021, Tuam Tshoj PVC xa tawm kev lag luam tau nthuav dav sai, thiab raws li tus nqi kom zoo dua, nws tau txais kev pom zoo los ntawm Is Nrias teb, Southeast Asia thiab lwm lub teb chaws, thiab cov xwm txheej PVC xa tawm muaj kev cuam tshuam ntau ntxiv rau kev lag luam hauv tsev. Lub peev xwm nce nrawm ntawm cov khoom siv ethylene suav nrog ntau qhov sib npaug, yog li ua kom muaj kev sib tw ntawm calcium carbide thiab cov txheej txheem ethylene. Los ntawm qhov kev xav ntawm cheeb tsam kev faib tawm ntawm lub peev xwm tsim tawm tshiab, lub peev xwm tsim tawm tshiab hauv 2023 yog qhov tseem ceeb hauv Shandong thiab South Tuam Tshoj.

2023 txhua xyoo muaj peev xwm tsim tau raws li cov txheej txheem sib txawv, feem ntau yog siv rau hauv cov tuam txhab calcium carbide, suav txog 75.13% ntawm lub tebchaws muaj peev xwm, vim tias Tuam Tshoj yog lub teb chaws muaj roj ntau dua thiab cov roj tsawg, thiab cov thee feem ntau yog faib rau hauv thaj av qaum teb sab hnub poob, qaum teb sab hnub poob cia siab rau cov nplua nuj thee, calcium carbide cov peev txheej, thiab cov lag luam feem ntau yog cov chaw txhawb nqa, yog li PVC muaj peev xwm tsim tau nyob rau sab qaum teb sab hnub poob yog qhov loj. North Tuam Tshoj, East Tuam Tshoj, South Tuam Tshoj nyob rau hauv xyoo tas los no, lub peev xwm tshiab yog tsuas yog ethylene tsim muaj peev xwm, vim hais tias ntawm ntug hiav txwv dej, yooj yim thauj, raw khoom ntshuam thiab kev thauj mus los.

Los ntawm qhov kev xav hauv cheeb tsam, thaj av qaum teb sab hnub poob tseem yog thawj zaug nrog 13.78 lab tons ntawm cov peev txheej tsim khoom. Raws li kev hloov pauv hauv cheeb tsam, South Tuam Tshoj tau ntxiv 800,000 tons ntxiv rau qhov sib txawv hauv zos, raws li qhov no, kev hloov pauv ntawm cov peev txheej hauv North Tuam Tshoj mus rau South Tuam Tshoj txoj kev lag luam tau nqaim, North Tuam Tshoj tsuas yog ntxiv ib txheej ntawm 400,000 tons ntawm cov khoom siv, thiab lwm thaj chaw. tsis muaj peev xwm tshiab. Zuag qhia tag nrho, nyob rau hauv 2023, tsuas yog South Tuam Tshoj, North China thiab Northwest Tuam Tshoj lub peev xwm ntau lawm yuav nce, tshwj xeeb tshaj yog nyob rau sab qab teb Tuam Tshoj, qhov chaw uas muaj peev xwm ntau lawm muaj kev cuam tshuam ntau dua. Lub peev xwm tshiab hauv 2024 yuav yog nyob rau sab hnub tuaj Tuam Tshoj.

2019-2023, Tuam Tshoj tus PVC kev lag luam muaj peev xwm txuas ntxiv nthuav dav, tau tsav los ntawm kev nce txhua xyoo hauv kev tsim khoom hauv xyoo tas los, kev tsim khoom hauv tsev PVC tau txuas ntxiv nthuav dav, 2019-2023 tsib xyoos ntawm kev nthuav dav ntawm 2.84 lab tons.

Vim muaj kev hloov pauv hauv Tuam Tshoj lub hauv paus muaj peev xwm nthuav dav thiab txawv teb chaws cov khoom lag luam thiab cov qauv xav tau, kev thauj khoom hiav txwv thiab lwm yam thiab cov cim qhia, Tuam Tshoj cov khoom lag luam tau poob qis tsis tu ncua, thiab kev cia siab ntawm cov ntshuam yuav tsum poob mus rau 1.74% hauv 2023. Nyob rau lub sijhawm ntev, nrog rau nce ntawm cov khoom siv hauv tsev, cov khoom lag luam zoo optimization, yav tom ntej cov khoom siv hauv tsev sib txawv yog khi kom maj mam txo.
