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.

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…
