To determine the amount of nitrogen required for superpressurization of FM-200™ at various fill densities, it isnecessary to understand the solubility relationship ofnitrogen and FM-200™. Extensive experimental work was

Recovery, Recycle, Reclamation, and Disposal

Reclamation

Responsible use of FM-200™ requires that the product be

Reclamation refers to the reprocessing of FM-200™

recovered for reuse or disposal whenever possible.

recovered from a system to new product specifications.

Recoveryanalysis. In the United States FM-200™ is included in

Recovery refers to the removal of FM-200™ from

Chemours reclamation program. Contact Chemours forequipment and collection in an appropriate container.
Recovery does not involve processing or analytical testing.
Recovery is normally performed when a system must
undergo maintenance, and the FM-200™ is then returnedto the system after completion. There are a number ofrecovery devices on the market. These devices contain acompressor and an air-cooled condenser and may be used
for liquid and vapor recovery. Before purchasing a specific
recovery unit, check with the manufacturer to be sure thatit contains the elastomeric seals and compressor oilcompatible with FM-200™.

Quality of the reclaimed product is verified by chemicalfurther information.
Disposal
Disposal refers to the destruction of used FM-200™.
Disposal may be necessary when FM-200™ has becomecontaminated with other materials and no longer meets theacceptable specifications of Chemours or other reclaimers.
Chemours does not presently accept severely contaminatedFM-200™ for disposal; licensed waste disposal firms areavailable. Be sure to check the qualifications of any firm
before sending them used FM-200™.
