Recovery, Recycling and Reclamation

The U.S. Clean Air Act J992, prohibits the intentional destruction of Halocarbon refrigerants into the atmosphere and requires recovery of refrigerant during repair or disposal of refrigeration equipment.

Recovery is a term that means removing die of the refrigerant from the system and saving it on the external containment vessel. The recovered refrigerant can be recycled, reclaimed or destroyed by burning, to prevent harm to the environment. When refrigerant is recovered, it can be transferred directly from the system in the storage cylinder, if it is in a liquid state. Otherwise, die translation is carried out by means of cooling storage cylinder in a decrease in pressure. In vapour refrigerant in the system will flow into the tank for storage of chilled force differential pressure creates. Keeping the temperature of the receiving cylinder cold allows the steam condenses, thereby preserving the differential pressure. Fluid pump can also be used for the transmission of some refrigerants. With any of these methods, as a rule, it is necessary to remove residual refrigerant through evacuation and condensation system restore.

Processing involves removing refrigerant from a system, its spread through the separator for oil and filter-dehydrator to remove any dirt.

This process can also be used to clean noncondensible gases from the cooling system. Recycling refrigerant typically occurs on the website of the equipment. Although recycling remove the most common contaminants such as oil, moisture, air, acids, sludge, varnish and solid particles from the refrigerant, it does not always return the refrigerant to the original specifications industry, as defined ARI (American refrigeration Institute). Degree of removal of pollutants depends on the complexity of recycling equipment, concentrations of contaminants and the skill of the technician. The only way to be sure that the refrigerant is responsible ARI Standard 700-88 specifications were analyzed by a qualified laboratory.

Schematic diagram of a few passage recycling unit. The system consists of an evaporator, oil separator, filter-drier, a compressor, a second oil separator, the condenser and the storage cylinder. Connect the equipment is made of holding a refrigerant for recovery through the entrance of the dispenser. As compressor disposal of the unit is receiving power, differential pressure develops through the dispenser. The liquid refrigerant flows through the metering device and the evaporator, where it evaporates. The oil is separated from the refrigerant in the evaporator sucked off the bottom of the coil. Filter-drier removes contaminants before the refrigerant vapour is included in the " basket " of the compressor.

Reset vapors pass through another oil separator before is condensed and going to in the storage cylinder. If the storage cylinder is connected back to the metering device, the refrigerant can make multiple passes through the separators and filters-driers, before he returned to die system. Each pass increases the opportunities to recycle unit to remove other pollutants from die refrigerant. If the plant is not used basket system becomes a single pass recycling unit. If turnaround cycle, oil separators and filters-driers are not used basket system becomes a simple recovery. The recycled refrigerant most often returned to the system from which it was removed. Charging system widi an uncertified refrigerant may void die manufacturers of equipment warranty.

Recovery of refrigerant is carried out on the remediation of the object where the recovered refrigerant is analyzed to determine the degree of its pollution. After determining taking into account the possibility of recovery of the refrigerant, it is reprocessed or destroyed by incineration. Reclamation process usually requires distillation and always includes analysis to ensure that the reclaimed refrigerant meets ARI Standard 700-88 specifications. Because of land reclamation process is complex, it is only performed by the chemical manufacturer of refrigeration and food processing...
