zida zazikulu zopangira styrene

Zida zazikulu zopangira styrene ndi polymerized grade ethylene ndi benzene yoyera, ndipo benzene yoyera imakhala ndi 64% ya mtengo wopanga styrene.Kusinthasintha kumodzi kwa styrene ndi mtengo wake wa benzene yoyera kudzakhudza kwambiri momwe kampaniyo imagwirira ntchito.Mtengo wa benzene yoyera umakhudza kwambiri mtengo wopangira styrene.Pakalipano, benzene yoyera imachokera ku ming'alu ya mafuta, kotero mtengo wa mafuta osayera umatsimikizira mtengo wa benzene weniweni.Mitengo yamafuta osakhwima yakwera m'zaka zaposachedwa, zomwe zapangitsa mitengo ya benzene yoyera.Komabe, ndi gawo lapakhomo la mabizinesi amagetsi a malasha kuti akhazikitse ukadaulo wapamwamba woyenga wa malasha wamafuta a benzol, amatulutsa zisonyezo kuti zikwaniritse zazikulu kuposa za petroleum benzene refined benzene, malasha amafuta a benzene asintha kusintha kwapang'onopang'ono. petroleum benzene, mitengo ya benzene yeniyeni ndi mitengo yamafuta zitha kupangitsa kuti pakhale kusokonekera, ndikutsitsa mtengo wamsika wa benzene yoyera.
