Jim Todack's Refrigerant Recovery and Recycling Patents
U.S. Pat. 5,709,091 - Refrigerant Recovery and Recycling Method and Apparatus

A portable refrigerant recovery and recycling system for removing and recycling chloroflourocarbon (CFC), hydroflourocarbon (HFC) and hydrochloroflourocarbon (HCFC) refrigerants from refrigeration systems. Closed loop interconnection prevents release of refrigerant to the atmosphere. By re-configuring connections to the refrigeration and storage system the stored refrigerant may be recycled through a distillation process which removes oil, water, acids and other solid particles. The distilled refrigerant is then recondensed and passed through high efficiency filters which further removes moisture and acids, thus rendering the refrigerant suitable for reuse.

U.S. Pat. 5,535,596 - Refrigerant Recovery and
Purification Apparatus and Method

A portable refrigerant reclamation and purification apparatus removes moisture, oil, solid particulates, non-condensables, acid and other contaminants from refrigerant. Contaminated refrigerant is introduced into a separation chamber and vaporized as it passes over heat exchanger coils. During vaporization the bulk of contaminants are separated from the refrigerant and fall into a sump and the vapors are redirected 180° to an upward flow separating the contaminants from the refrigerant vapors. The vapors are drawn out of the chamber through demisting screens which strip remaining contaminants from the vapors and pass through a suction accumulator to either a compressor. The compressed gases are passed through an oil separator. and then either through the heat exchangers in the separation chamber to vaporize incoming liquid refrigerant, or to a condenser coil and then passed through a sub-cooling coil in the chamber over which the vapors drawn from the chamber pass, to lower the temperature of the refrigerant in the sub-cooling coil. The sub-cooled liquid refrigerant passes through a receiver where non-condensables are separated and purged from the system and the condensed liquid refrigerant is then passed through filters.

U.S. Pat. 5,363,662 - Refrigerant Recovery and
Recycling Method and Apparatus

A portable refrigerant recovery and recycling apparatus and method for removing and recycling chloroflourocarbon (CFC), hydroflourocarbon (HFC) and hydrochloroflourocarbon (HCFC) refrigerants from refrigeration systems through a closed loop connection which prevents the release of refrigerant to the atmosphere. A refrigerant is drawn by suction through a filter in its liquid state and transferred to a storage tank. When all liquid refrigerant has been so transferred, a refrigerant vapor recovery process automatically engages and retrieves and condenses the remaining refrigerant vapors, thus completing evacuation of the closed loop refrigeration system until the refrigeration system is evacuated to a pressure of approximately 29 inches Hg absolute for low pressure refrigeration systemes and 20 inches Hg absolute for high pressure refrigeration systems, at which time the present invention automatically shuts off. By re-configuring connections to the refrigeration and storage system the stored refrigerant may be recycled through a distillation process which removes oil, water, acids and other solid particles. The distilled refrigerant is then recondensed and passed through high efficiency filters which further removes moisture and acids, thus rendering the refrigerant suitable for reuse.
