Which process applies to cleaning refrigerant for immediate reuse by oil separation and single or multiple passes through devices, like replaceable core filter driers, which reduce moisture and acidity

Recycling.

Explanation:

Recycling can be defined as the process of gathering, processing and conversion of waste materials such as thrash or scraps into new materials or products. Thus, recycling facilitates the reuse of materials that could have been disposed off as waste or thrash.

Hence, recycling is a process which applies to cleaning refrigerant for immediate reuse by oil separation and single or multiple passes through devices, like replaceable core filter driers, which reduce moisture and acidity. This simply means that, refrigerants can be cleaned for reuse by using an oil separation technique to remove the residual refrigerant oil and then a filter-drier to reduce moisture and acidity.
