Cov ntaub ntawv tseem ceeb rau kev tsim cov styrene yog polymerized qib ethylene thiab ntshiab benzene, thiab cov ntshiab benzene suav rau 64% ntawm cov nqi tsim khoom ntawm styrene.Ib qho kev hloov pauv ntawm styrene thiab nws cov khoom siv raw khoom ntshiab benzene tus nqi yuav muaj kev cuam tshuam zoo rau lub tuam txhab kev ua lag luam.Tus nqi ntawm cov ntshiab benzene muaj kev cuam tshuam zoo rau cov nqi tsim khoom ntawm styrene.Tam sim no, ntshiab benzene feem ntau yog los ntawm cov roj tawg, yog li tus nqi ntawm cov roj crude txiav txim siab tus nqi ntawm cov ntshiab benzene.Cov nqi roj Crude tau nce nyob rau hauv xyoo tas los no, ua rau cov nqi siab ntawm cov ntshiab benzene.Txawm li cas los xij, nrog rau ib feem ntawm cov chaw lag luam tshuaj lom neeg los ua kom paub cov thev naus laus zis thev naus laus zis ntawm thee crude benzol refining, tsim cov ntsuas kom ua tiav ntau dua li cov roj av benzene refined benzene, thee puag ntawm ntshiab benzene ntau lawm yuav hloov ib qho khoom siv ntawm cov khoom. roj av benzene, cov nqi benzene ntshiab thiab cov nqi roj tuaj yeem ua rau muaj qee qhov kev sib txawv, thiab txo tus nqi lag luam ntawm cov ntshiab benzene.
