Umzi-mveliso wePetrochemical ubukhulu becala ishishini lekhemikhali elisebenzisa ioli evuthayo, irhasi yendalo kunye nezinye izinto ezingafunekiyo kwidizili, i-kerowsene, i-perlibe, i-perber, iifilimi kunye nezinye iimveliso ezithengiswayo. Igesi yerhasi yeShishini kunye neGalk Bulk idlala indima ebalulekileyo kulo mzi mveliso. I-Acetylene, i-Ethylene, i-propynene, i-broplene, i-Butadiene kunye nezinye iigasethi zemveliso zizixhobo ezisisiseko zeshishini lePetrochemical.
