Notes:

The previous animation has been greatly simplified to convey theory of the Process Pigging System. Implementation of three-way valves and other fittings (not shown) may be required in order to achieve the illustrated product flows. However, it is easy to see how with the addition of the Process Pigging System, enormous savings can be gained.

Additional applications (also not shown) can be solvent flushes in between batches, if product type requires. The important difference is that with a very small amount of solvent, placed in between two pigs, can be run through the line, rather than having to fill entire line with solvent. Obviously, this equates to additional savings, but furthermore, because the pigs have removed the majority of product (up to 99% in a single run), the small slug of solvent could be re-used several times before having to be disposed, increasing savings further.

Also, by adding Pig Passage Indicators and solenoids to actuate valves, the entire system can be fully automated, or can be operated by a single operator in a control room with the push of a single button.
