Two distillation columns are being used to separate a methanol-benzene mixture fed at 1000 kg-mol/hour. The feed stream is a temperature of 100degC and has composition 30% methanol and 70% benzene. The target objective is to generate two product streams, one containing 95% benzene and another containing 90% methanol. Design a process that uses two distillation columns with different operating pressures (from 0.1 to 2 bar) to carry out this separation.
