Storage in Batch Processes

The storage requirements associated with continuous processes were discussed in Chapter 13. The minimum storage volume in batch processes is equal to the delivered batch size for feed materials, or the manufactured quantity per batch for the product. 

Because batch processes are in a dynamic state, it can be difficult to maintain the required product specification throughout the batch. Thus, storage can help to dampen out variations in product quality for fluid products. Variations in the outlet properties from the storage are reduced compared with variations in the inlet properties for fluid products. As long as the mean quality is within specifications, all of the product can be sold.
