Benzene Production From Toluene Cost Analysis Benzene E31a

This report presents a cost analysis of Benzene production from toluene. The process examined is a typical selective toluene disproportionation process (STDP). In the STDP, toluene is converted into benzene and xylenes (mainly, p-xylene). Benzene is recovered from the reactor output via distillation and p-Xylene is separated as a by-product using a crystallization unit.
