3. We are separating hydrocarbons in a column that has two feeds. The column operates at 75 psig. It has a total condenser and a partial reboiler. The first feed is 30 wt% ethane, 0.6 wt% propylene, 45 wt% propane, 15.4 wt% n-butane, and 9 wt% n-pentane. This feed is a saturated liquid at a flow rate of 1000 kg/h. The second feed is 2.0 wt% ethane, 0.1 wt% propylene, 24.9 wt% propane, 40.0 wt% n-butane, 18.0 wt% n-pentane, and 15.0 wt% n-hexane. The flow rate of this feed is 1500.0 kg/h. It is a saturated liquid. We desire 99.1% recovery of the propane in the distillate and 98% recovery of the n-butane in the bottoms. Make appropriate assumptions and calculate the distillate and bottoms flow rates. Also calculate the weight fractions of each component in the distillate and bottoms streams. 3.
