A liquid has the following composition in mol%: Propane 1.36%, i-Butane 14.33%, n-Butane 16.37%, i-pentane 15.66%, n-Pentane and n-Hexane 17.88% each. The mixture must be separated into a column, with 95% of the n-butane that enters the feed must leave in the distillate and 98% of the isopentane that enters must come out at the bottom. The Column has a pressure at 30 psia and uses a condenser that operates at 10.78 ºC and a cooler that operates at 63.33 ºC. Making the pertinent considerations, Calculate the minimum number of theoretical stages required. Determine the distribution of components in the distillate and in the background.
