🔍 Key Concepts

• Difference between recovery, recycling, and reclamation of refrigerant • What reclamation equipment can and cannot remove from refrigerant (solid, liquid, and gaseous contaminants) • How mixtures of different refrigerants behave compared to a single, pure refrigerant

💭 Think About

• For each option, ask yourself: can this contaminant be filtered, dried, or separated by normal reclamation equipment? • Consider which contaminant changes the chemical identity or composition of the refrigerant in a way that is hard to reverse. • Think about how easy it is to vent, boil off, or absorb each type of contaminant during processing.

✅ Before You Answer

• Be clear on the difference between removing moisture, acid, and particulates versus separating different refrigerant types from each other. • Recall that some contaminants can be handled with filters, dryers, and oil separators, while others require much more complex separation methods. • Before choosing, ask: does this contaminant result in a mixture of different refrigerants or just impurities within one refrigerant?
