A chemical plant needs to separate a mixture of benzene and toluene using a distillation column. The feed contains 40% benzene and 60% toluene. Design a distillation column to achieve a distillate with at least 90% purity of benzene. Provide the reflux ratio and the number of theoretical trays required to meet the purity specification. Assume an operating pressure of 1 atm and th
