Question:

It is desired to produce three different products, A, B, and C, using the same equipment in a batch processing plant. Each production method uses the same equipment in the same order for the times given in Table P3.13.Table P3.13 Equipment Processing Times for Problem 3.13 Equipment Process Mixer Reactor Filter

C 2.0 h 3.5 h 5.0 h 4.0 h 850 kg/m

It has been determined that market forces dictate that the rate of production of product B should be twice that of A and for C should be three times that of A. For a one-month campaign, equivalent to 600 h, answer the following questions:

  • Assume that each product will be produced in separate campaigns; for example, first make all A, then B, then C. Determine the number of batches for each product.
  • If the yearly demand for product C is 180,000 kg/y (180 tonne/y), determine the storage capacity (volume) for this product assuming constant demand for C throughout the campaign period.
  • Determine the number of batches that could be produced during a 600 h period if the multibatch sequence ABBCCCABBCCC … is used.
