Question 1 (34 marks)Methanol and water distillation is carried out in a column with sieve trays. Thebottoms composition is 0.01 Ibmol % methanol. The column operates at 1 atmpressure. The feed to the column is a saturated liquid at 1000 Ibmol/hr and is 40mol % methanol. L/D = 2.0. The distillate product is 99.8 Ibmol % methanol. Usea 12 inch tray spacing and ŋ = 0.85. The liquid surface tension of pure water is σ= 58.9 dynes/cm at 100 °C. Density of water at 100 °C = 59.83 lbm/ft³. Hole area(Ah) to active area (A₁) ratio is assumed to be 0.1. If we operate at a vapor flowrate that is 80% of flooding, calculate the diameter based on conditions at thebottom of the column.Additional information:Universal gas constant = R = 1.314 atm-ft³/ K-lbmolIdeal gas law hold true.

Rare Bhd. produces 'Rare Q' in a lengthy mixing and cooling process. Base materials are introduced at the start of this process, and further chemicals are added when it is 80% complete. Each kilogram of base materials produces 1 kilogram of Rare Q. Data for October are: Opening work in process: 40 kg of base materials, 25% processed Cost of opening work in process: Base materials RM1,550 Processing RM720 Costs incurred in October: Conversion costs RM6,864 Further chemicals RM7,200 Closing work in process: 50kg of base materials, 90% processed Finished output: 65 kg of Rare Q. Under normal conditions there are no losses of base materials in this process. However, in October, 5kg of partially complete Rare Q were spoiled immediately after the further chemicals had been added. The 5kg of spoiled Rare Q were not processed to finished goods stage and were sold for a total of RM200. Using the FIFO method, calculate the value of Cost of conversion cost per equivalent unit.

The abnormal spoilage is 300 units and the cost per equivalent unit is $2 for direct materials and $3 for conversion. The inspection point is at the end of processing. There are 600 units in ending Work-in-Process and normal spoilage is 200 units. What are the equivalent units for material and conversion using the weighted -average method and the FIFO method? Please provide an explanation of the calculation.

1. A protein chromatography column that processes 15 kg of protein in 60 h, is cycled every 6 h, can be loaded with 10 grams of protein per liter of column volume, has a maximum flow rate of 50 liters/ min at a pressure of 4 bar, and is packed with an incompressible resin having a particle diameter of 90 μum and void fraction of 0.35. The viscosity can be assumed to be that of water. i. What are the dimensions required for the column? ii. If the flow rate is 1 column volume per minute and the pressure rating is still 4 bar, what column dimensions are required? Is the resolution equivalent to that for Part (i)? 111. If the pressure rating for the column were raised to 12 bar, should the column dimensions change? Is so, what should the dimensions be? Do they make sense? iv. What is the best way to increase the productivity of the column packing?

Parts are produced in batch slzes of 60 parts, A part requires 3 minutes in milling and 9 minutes in finishing. The move time between the two operations for a complete batch is 10 minutes. Under the lean philosophy, the part is produced in a cell that Includes both the milling and finishing operations. The operating time is unchanged; however, the batch size is reduced to 5 parts and the move time is eliminated. Determine the value-added, non-value-added, and total lead times, and the value-added ratio under the traditional and lean manufacturing methads. If required, round percentages to one decimal place.
