Product recovery techniques
Manufacturers of chemical products often need to clean processing equipment between different batches of products. To do this, they need to remove the existing product from pipelines and vessels. Product loss and waste generation resulting from the cleaning of processing equipment increase production costs and have a negative impact on sustainability. Product recovery is typically done in combination with Clean-in-Place. This presentation introduces the reader to two techniques for product recovery: pigging and whirlwind systems. Design considerations, advantages & disadvantages as well as case studies are presented for both techniques.

Key Messages
Product loss and waste generation resulting from the cleaning of processing equipment increase production costs and have a negative impact on sustainability. Product recovery is typically done in combination with Clean-in-Place.
The product (e.g. cosmetics, paints, polymers, etc.) remaining in the pipelines and process equipment has economic value and can be recovered using the following techniques:
- Pigging systems
- Whirlwind systems
