1. One hundred tons per hour of a feed containing 20 wt% Na2CO3 and the balance insoluble solids is to be leached and washed with water in a continuous, countercurrent system. Assume leaching will be completed in one ideal stage. It is desired to obtain a final extract containing 15 wt% solute, with a 98% recovery of solute. The underflow from each stage will contain 0.5 lb solution/lb insoluble solid. Determine the number of ideal washing stages using both graphical and analytical solutions.

8. 9. butane is consumed, and the product gas contains 9 mol CO2 per mol CO. Calculate the molar flow rate of water in the stack gas. Butane is completely burned in a process fed with 25.0% excess air. Based on 1 mol/h of butane, determine the composition in mole fractions of oxygen in product stream. Methane at a molar flow rate of 55 mol/min is burned with dry air. A partial analysis of the exit gas reveals that the mole fraction of nitrogen is 0.85 on a dry basis, and the molar flow rate of the dry exit gas is 600 mol/min. P
An extraction experiment was carried out with the soxhlet extraction technique to obtain oil from a plant seed. In the experiment, 10 g of plant seeds were taken and extracted with 150 mL of hexane solvent, The oil-hexane mixture obtained at the end of the extraction will be separated in the rotary evaporator and the mass and percent extraction efficiency of the collected oil will be calculated. The data obtained at the end of the experiment are given in the table below. Accordingly, calculate the amount of oil obtained, the amount of oil obtained per 1 g of plant seed and the percent extraction efficiency by establishing a mass conservation balance around the rotary evaporator.

Q3/ A 100 mole feed containing equimolar amounts of methanol and water is mixe with 10 moles of a 40 mole% aqueous methanol stream. The mixture enters a distillation column that creates two streams. A top stream exits that contains 70 mole% methanol and balance with water. The bottom stream, which is 70 moles, enters a second distillation column. A top stream exits the second column as a 50% methanol and 50% water. The two top streams exiting the distillation column have the same flow rate. Calculate all unknown streams variables.
