Raws li cov ntaub ntawv xyoo 2020, tag nrho cov peev xwm tsim khoom PVC thoob ntiaj teb tau txog 62 lab tons thiab tag nrho cov zis tau txog 54 lab tons. Tag nrho cov kev txo qis hauv cov zis txhais tau tias lub peev xwm tsim khoom tsis khiav 100%. Vim muaj kev puas tsuaj ntuj tsim, cov cai hauv zos thiab lwm yam, cov zis yuav tsum tsawg dua li lub peev xwm tsim khoom. Vim yog tus nqi tsim khoom siab ntawm PVC hauv Tebchaws Europe thiab Nyiv Pooj, lub peev xwm tsim khoom PVC thoob ntiaj teb feem ntau yog nyob rau sab qaum teb sab hnub tuaj Asia, uas Tuam Tshoj muaj kwv yees li ib nrab ntawm lub peev xwm tsim khoom PVC thoob ntiaj teb.
Raws li cov ntaub ntawv cua, xyoo 2020, Tuam Tshoj, Tebchaws Meskas thiab Nyiv Pooj yog cov chaw tsim khoom PVC tseem ceeb hauv ntiaj teb, nrog rau lub peev xwm tsim khoom suav txog 42%, 12% thiab 4% feem. Xyoo 2020, peb lub tuam txhab saum toj kawg nkaus hauv lub ntiaj teb PVC txhua xyoo muaj peev xwm tsim khoom yog Westlake, shintech thiab FPC. Xyoo 2020, lub peev xwm tsim khoom PVC txhua xyoo yog 3.44 lab tons, 3.24 lab tons thiab 3.299 lab tons feem. Qhov thib ob, cov tuam txhab uas muaj peev xwm tsim khoom ntau dua 2 lab tons kuj suav nrog inovyn. Tuam Tshoj lub peev xwm tsim khoom tag nrho yog lwm 25 lab tons, nrog rau cov zis ntawm 21 lab tons hauv xyoo 2020. Muaj ntau dua 70 lub tuam txhab tsim khoom PVC hauv Suav teb, 80% ntawm cov no yog calcium carbide txoj kev thiab 20% yog ethylene txoj kev.
Feem ntau ntawm cov txheej txheem calcium carbide yog nyob rau hauv cov chaw nplua nuj nyob rau hauv cov thee xws li Inner Mongolia thiab Xinjiang. Lub chaw cog qoob loo ntawm cov txheej txheem ethylene nyob rau hauv thaj chaw ntug dej hiav txwv vim tias cov khoom siv raw VCM lossis ethylene yuav tsum tau xa tuaj. Tuam Tshoj lub peev xwm tsim khoom suav rau yuav luag ib nrab ntawm lub ntiaj teb, thiab nrog rau kev nthuav dav ntawm Tuam Tshoj txoj kev lag luam upstream, lub peev xwm tsim khoom PVC ntawm txoj kev ethylene yuav txuas ntxiv mus nce ntxiv, thiab Tuam Tshoj yuav txuas ntxiv mus rau kev rhuav tshem cov khoom sib koom PVC thoob ntiaj teb.
