Intended learning outcomes: Differentiate between batch production and continuous production. Explain the criteria that are important for the decision for one or the other of these concepts.
As a producer of fine chemicals, you plan to introduce a new type of solvent to the market. It is suitable for use in the production of adhesives for the automobile industry. The corporate marketing department estimates that 5000 to 10,000 tons of the product can be sold per year. The product design with laboratory tests has been completed. But the industrial production concept for the product remains to be determined. While most of the production processes are actually done on the batch principle (discontinuous or batch production), your engineers now suppose continuous production for this product.
a. What are the differences between these two concepts? What criteria are important for the decision for one or the other of these concepts?
b. What is your suggestion regarding the new solvent? Explain the reasons for your decision.
Solution:
a.
In selecting the appropriate production principle, the following points have to be considered:
- Production volume and regularity of demand
- Need for flexibility
- Requirements in terms of proof of origin and quality control
- Technological conditions and safety requirements
b.
In the case of the solvent, the preferred principle could be continuous flow production. The production volume is of adequate size for small facilities for continuous production. Furthermore, it can be assumed that the consumption of the new product will run relatively regularly. At least a proof of origin is not necessary.
