Thaum Lub Kaum Hli, kev ua lag luam acetone hauv Suav teb tau ntsib kev poob qis hauv cov khoom lag luam nce thiab nqis qis, nrog cov khoom lag luam tsawg tsawg tau nce ntau.Qhov tsis sib xws ntawm kev xa khoom thiab kev thov thiab tus nqi siab tau dhau los ua qhov tseem ceeb ua rau kev lag luam poob qis.Los ntawm qhov kev xav ntawm qhov nruab nrab cov nyiaj tau los, txawm tias cov khoom siv hluav taws xob tau nce me ntsis, cov nyiaj tau los tag nrho tseem yog qhov tseem ceeb hauv cov khoom lag luam downstream.Nws cia siab tias thaum lub Kaum Ib Hlis, cov khoom lag luam acetone nce siab yuav tsum tau ua tib zoo saib xyuas cov khoom siv thiab xav tau kev ua si qhov xwm txheej, thiab kev ua lag luam yuav qhia tau tias muaj kev hloov pauv thiab ua haujlwm tsis muaj zog.

Thaum Lub Kaum Hli, tus nqi nruab nrab txhua hli ntawm acetone thiab cov khoom lag luam nyob rau hauv cov kev lag luam sab saud thiab qis qis tau pom qhov sib txawv ntawm kev poob lossis nce.Tshwj xeeb, tus nqi nruab nrab txhua hli ntawm acetone thiab MIBK tau nce lub hli ntawm lub hli, nrog nce ntawm 1.22% thiab 6.70%, feem.Txawm li cas los xij, tus nqi nruab nrab ntawm cov dej ntws ntshiab huv benzene, propylene, thiab cov khoom qis qis xws li bisphenol A, MMA, thiab isopropanol tau poob rau qhov sib txawv.Qhov tsis sib xws ntawm cov khoom siv thiab kev xav tau thiab tus nqi siab tau dhau los ua qhov tseem ceeb ua rau tus nqi poob.

Los ntawm qhov kev xav ntawm qhov kev xav ntawm qhov nruab nrab cov nyiaj tau los, qhov nruab nrab cov nyiaj tau los ntawm cov dej ntshiab benzene thiab propylene nyob rau lub Kaum Hli yog nyob ze ntawm cov nyiaj tau los thiab cov kab poob, nrog ib qho zoo thiab lwm qhov tsis zoo.Raws li cov khoom lag luam nruab nrab hauv cov saw hlau, acetone tau hloov nws cov nqi nruab nrab vim yog cov khoom siv nruj thiab kev them nyiaj yug.Nyob rau tib lub sijhawm, phenol cov nqi tau qis dua thiab rov zoo dua, ua rau ze li ntawm 13% nce hauv cov txiaj ntsig tag nrho ntawm phenol ketone factories piv rau lub hli dhau los.Txawm li cas los xij, hauv cov khoom lag luam qis, tshwj tsis yog qhov nruab nrab cov txiaj ntsig ntawm bisphenol A hauv qab cov nyiaj tau los thiab cov nyiaj poob, qhov nruab nrab cov nyiaj tau los ntawm MMA, isopropanol, thiab MIBK yog tag nrho saum cov nyiaj tau los thiab cov kab poob, thiab MIBK cov txiaj ntsig tau txiav txim siab, nrog rau cov nyiaj tau los. lub hli ntawm lub hli nce ntawm 22.74%.

Nws cia siab tias thaum lub Kaum Ib Hlis, cov khoom lag luam acetone hauv kev lag luam yuav nthuav tawm qhov kev ua haujlwm tsis muaj zog thiab tsis muaj zog.Yog li ntawd, nws yog ib qho tsim nyog yuav tsum ua tib zoo saib xyuas cov kev hloov pauv ntawm cov khoom siv thiab kev xav tau, nrog rau kev taw qhia ntawm kev lag luam xov xwm, thaum tseem ua tib zoo saib xyuas cov kev hloov pauv thiab kev siv ntawm cov nqi sib kis.
