Question:

Consider the process given in Problem 3.8. Assuming that a single-product campaign strategy is used over a 500 h operating period and further assuming that the production rates (for a year = 6000 h) for products A, B, C are 18,000 kg/y, 24,000 kg/y, and 30,000 kg/y, respectively, determine the minimum volume of product storage required. Assume that the product densities of A, B, and C are 1100, 1200, and 1000 kg/m3, respectively.


Problem 3.8

Consider the multiproduct batch plant described in Table P3.8.Table P3.8 Equipment Processing Times for Processes A, B, and C Process Mixer Reactor Separator

A B C 2.0 h 5.0 h 3.0 h 4.0 h 1.0 h 3.0 h 4.0 h 3.5 h 4.5 h

It is required to produce the same number of batches of each product. Determine the number of batches that can be produced in a 500 h operating period using the following strategies:

  • Single-product campaigns for each product
  • A multiproduct campaign using the sequence ABCABCABC…
  • A multiproduct campaign using the sequence CBACBACBA…
