A refrigerant recycling system (10) has a compressor (12) and identical first and second drier/separators (18, 20). Refrigerant material to be reclaimed is drawn into an inlet (22) of the first drier/separator, in which lubricant is separated from refrigerant vapor. After the lubricant is removed, the refrigerant vapor is filtered as it passes through a screen (80), a bed of molecular sieve material (82), and a fibrous pad (84). After passing through the first drier/separator, the refrigerant enters the compressor in which clean lubricant material is introduced to enable the compressor to operate effectively. From the compressor, the refrigerant vapor and clean lubricant passes through the second drier/separator wherein the clean lubricant is removed and the refrigerant vapor is again filtered. The twice filtered vapor is then passed to a condenser (44) in which it is condensed to a liquid. The clean refrigerant liquid is delivered from the reclamation system cleansed of impurities.

A method for removing compressor lubricant, water and particles from vapor refrigerant in a refrigerant recycling system, comprising the steps of: locating a vapor drier/separator in the refrigerant recycling system to receive the vapor refrigerant, said vapor drier/separator including a body having a top, a bottom, and an internal chamber, filter material for removing lubricant, water and particles located within said internal chamber, an imperforate conduit extending from the top of the body to a lower separation chamber at the bottom of the body, and a drain in the separation chamber; directing the vapor refrigerant with compressor lubricant, water and particles into an inlet opening in the top of the vapor drier/separator body and vertically downward through the conduit toward the bottom of the body directly into the lower separation chamber; separating out by quiescent action the compressor lubricant from the vapor refrigerant in the separation chamber; periodically draining the lubricant out of the separation chamber through the drain in the separation chamber; directing the vapor refrigerant vertically upward through the filter material toward the top of the body and removing the water and particles from the vapor refrigerant, and directing the filtered vapor refrigerant through an outlet in the top of the vapor drier/separator body.
