Introduction
Aromatichydrocarbonsareanimportantclassofindustrialchemicalsthathaveawiderangeofapplicationsintheproductionofchemicals,plastics,andfuels.Themainfeedstockfortheproductionofaromatichydrocarbonsispetroleum,whichisafiniteresourceandsubjecttopricefluctuations.Inrecentyears,therehasbeenanincreasingfocusontheproductionofaromatichydrocarbonsfromalternativefeedstocks,suchascoal,biomass,andnaturalgas.Thispaperpresentsanoptimizationsimulationofanaromatichydrocarbonproductionplantthatusesavarietyoffeedstocks.
