A mixture of ethyl benzene (15 wt%), ortho-xylene (20 wt%), meta-xylene (30 wt%), and para-xylene (35 wt%) is fed to a distillation column at a rate of 20,000 kg/hr. Three streams leave the column. Outlet A has a flowrate of 1400 kg/hr and contains ethyl benzene (96 wt%), meta-xylene (3 wt%) and para-xylene (1 wt%). Outlet B has a flowrate of 6000 kg/hr, has an ortho-xylene flowrate of 500 kg/hr, and contains 10 mass% of the para-xylene that entered the column. Outlet C contains no ethyl benzene. What is the mass fraction of ethyl benzene in Outlet B? What is the mass fraction of ortho-xylene in Outlet, what is the mass fraction of para-xylene in Outlet C? What is the mass fraction of meta-xylene in Outlet C?
