Reaction and Separation Systems for Batch Processes - Summary

11 REACTION AND SEPARATION SYSTEMS FOR BATCH PROCESSES - SUMMARY 

Many batch processes are designed on the basis of a scale-up from the laboratory, particularly for the manufacture of specialty chemicals. Particularly when manufacturing specialty chemicals, the shortest time possible to get a new product to market is often the biggest priority (accepting that the product must meet the specifications and regulations demanded and the process must meet the required safety and environmental standards). This is particularly true if the product is protected by patent. 

For batch reactors the four major factors that effect batch reactor performance are  

Batch distillation has a number of advantages when compared with continuous distillation  

Crystallization is extremely common in the production of fine and specialty chemicals. Many chemical products are in the form of solid crystals. Also, crystallization has the advantage that it can produce a product with a high purity and can be more effective than distillation from the separation of heat-sensitive materials. Batch crystallization is
