Which process applies to cleaning refrigerant for immediate reuse by oil?

The process that applies to cleaning refrigerant for immediate reuse by oil is called refrigerant reclamation. This involves filtering and purifying the refrigerant to remove contaminants, moisture, and acids, typically through distillation or other separation techniques. After reclamation, the cleaned refrigerant can be reused in HVAC systems, ensuring it meets the necessary purity standards. This process is essential for maintaining system efficiency and environmental compliance.
