A hydrocarbon feed consisting of a mixture of propane (20%), isobutene (30%), isopentane (20%), and n-pentane (30%) is fractionated at a rate of 100 kg/h into a distillate that contains all the propane and 78% of the isopentane in the feed. The mole fraction of isobutane in the distillate is 0.378. The bottom stream contains all the n-pentane fed to the unit. Determine the flow rate of the bottom stream. provide a flow chart with component and mass of each inlet and outlet

A mixture of propane, butane and pentane are to be separated in a distillation column. Feed= Propane - 20 wt % Butane - 50 wt% Pentane - 30wt%. Top=Propane – 93 wt% Butane - 7 wt% Pentane – 0 wt%. Bottom=Propane - ?? wt % Butane - ?? wt% Pentane - 38 wt%. The weight % values shown are compositions. The total feedrate is 5000 kg hr-1. ALL the pentane is recovered in the bottom product, (comprising 38 wt% of...

A closed system contains an equimolar mixture of n-pentane and isopentane. a) Suppose the system is initially all liquid at 120°C and a high pressure, and the pressure is gradually reduced at a constant temperature. Estimate the pressures at which the first bubble of vapor forms and at which the last drop of liquid evaporates. Also calculate the liquid and vapor compositions (mole fractions) at those two conditions. b) Now suppose the system starts as a vapor at 1960 mm...

A distillation column receives a feed that is 40 mole % n-pentane and 60 mole % n-hexane. The feed is saturated liquid at 2,500 lbmol/hr. The column is at 1 atm. A distillate that is 97 mole % n-pentane is desired. A total condenser is used. The reflux is a saturated liquid. The external reflux ratio is L0/D = 3. The bottoms from the partial reboiler is 2 mole % n-pentane. Determine the intersection (xq, yq) of the q-line with...

Propane is mixed with 20% excess air (propane air mixture is initially at 25 °C and 2.0 atm) and combusted at atmospheric pressure. It is assumed that the heat transfer between the chamber and the surroundings is negligible. In addition, you may assume that heat capacities of the gases are constant and that the reaction proceeds to 100% conversion. (30 points) a) Determine the flame temperature of the burner. b) Determine the flame temperature if 25% of the heat generated...

A mixture containing 20 mole % butane, 35 mole % pentane and 45 mole % hexane is to be separated by fractional distillation into a distillate product with a composition 95 mole % butane, 4 mole % pentane and 1 mole % hexane, and a bottoms product. The recovery of butane in the distillate must be 90%. Determine the composition of the bottoms product.
