A refrigerant recovery processing and storage unit (RPSU) for removing and storing refrigerant from an air conditioning and refrigeration system (AC&R) is disclosed. The unit creates a pressure difference between the inlet and outlet side of the AC&R, and a pressurized motivating gas is delivered to the inlet and flows therethrough to the outlet. The pressurized gas flow drives the refrigerant fluid from the AC&R. The RPSU separates the mixed refrigerant from the pressurized gas, and delivers the separated refrigerant to a detachable storage unit. After the AC&R is repaired, the refrigerant is returned from the storage tank to the AC&R.
