Tsis ntev los no, lub 90000 T / a olefin catalytic cracking (OCC) chav nrog lub thev naus laus zis tiav ntawm Shanghai lub koom haum roj av thiab kev lag luam chemical (tom qab no hu ua" Shanghai lub koom haum") tau pib ua tiav hauv LianHong Tshiab Cov Khoom Siv Tshuab Co ., Ltd., cim kev hloov pauv ntawm kev hloov tshiab ntawm tiam tshiab OCC thev naus laus zis ntawm Shanghai lub koom haum roj av thiab tshuaj lom neeg kev lag luam (tom qab no hu ua" Shanghai lub koom haum") thiab kev nruam tshiab thiab kev txhim kho kev txhim kho.
OCC yog thev naus laus zis tshiab los hloov C4 / C5 olefins rau hauv propylene thiab ethylene, uas tau dhau los ua ib qho tseem ceeb hauv kev txhim kho olefin ntau lawm. Txij xyoo 2000, Shanghai lub koom haum thev naus laus zis tau pib kawm OCC thev naus laus zis. Nyob rau xyoo 2009, nws pom tau hais tias kev hloov kho kev lag luam yog thawj zaug, thiab ua tiav cov chaw tsim khoom hauv Zhongyuan Petrochemical, Zhongtian hechuang thiab Zhongan thee siv tshuaj. Xyoo tsis ntev los no, Shanghai lub koom haum thev naus laus zis tau pib txoj kev loj hlob ntawm lub cim tshiab ntawm cov txiaj ntsig OCC thev naus laus zis, tau tsim cov cim hluav taws xob tshiab, thiab kev hloov pauv cov txheej txheem tshuaj tiv thaiv. Kev tsim tawm ntawm diene (propylene ntxiv rau ethylene) tau hloov kho ntau. Thaum Lub Kaum Hli 2020, lub cim tshiab ntawm OCC thev naus laus zis tau ua tiav qhov kev hloov pauv ntawm kev lag luam. Tam sim no, txoj haujlwm khiav haujlwm ruaj khov, kev thauj khoom noj ntawm lub reactor tau nce mus txog 108%, thiab cov diene tawm ntau dhau tus nqi cog lus.
Cov kws tshaj lij hais tias qhov muaj kev vam meej kev hloov pauv ntawm tiam tshiab ntawm OCC thev naus laus zis yog qhov txhim kho ntawm Shanghai lub koom haum' s ywj pheej kev muaj peev xwm thiab ua lub luag haujlwm tseem ceeb hauv kev nthuav dav lag luam ntxiv. Tom qab ua tiav ntawm txoj haujlwm, nws yuav ua kom zoo tshaj qhov tsim tawm ntawm ethylene thiab propylene, txhim kho cov khoom muaj txiaj ntsig ntawm C4 cov khoom siv, thiab muab kev txhawb nqa kev lag luam rau cov lag luam kom txo nqi thiab nce kev ua haujlwm.
Daim ntawv thov ntawm OCC thev naus laus zis hauv kev lag luam chemical chemical tau txhim kho txoj kev sib tw ntawm thee rau olefin kev lag luam. Ntxiv rau, OCC thev naus laus zis tseem tuaj yeem muab cov kev daws teeb meem hauv kev tsim cov tshuaj lom neeg, kho nrog roj txhim kho, thiab txhim kho olefin tawm los ntawm cov nroj tsuag ethylene. Olefin cov txheej txheem tawg tau dhau los ua tus choj tseem ceeb txuas rau roj av thiab cov khoom siv roj av nrog cov khoom siv propylene thiab ethylene hauv kev lag luam petrochemical thiab thee tshuaj lom neeg, thiab muaj cov ntawv thov dav.
