  • NAG non-condensable gases
  • NAG non-absorbable gases
  • concentration of non-condensable gases (NCG) or non-absorbable gases (NAG) may vary or be altered, resulting in a concentration of less than 1 .5 volume percent at 25°C, per AHRI 700, preferably below 0.9 volume percent at 25°C per AHRI 700.
  • NAG typically comprises air, (which is typically comprised of 78% nitrogen, 21 % oxygen, and about 1 % argon), accumulated in the vapor phase of refrigerants where the solubility of air in the liquid phase is extremely low. While reducing the total amount of NAG contained within liquid may be important, it is typically more desirable to reduce the oxygen containing portion of the NAG preferentially over the nitrogen portion.
  • the concentration could vary due to the amount of blowing agent used to create the foam, the amount lost to atmosphere during the life of the foam, the amount of air that infiltrates the foam during the life of the foam, as well as the amount of air introduced during reclaiming and/or recycling process, and the efficiency of the foam pulverization.
  • foam waste is sent through a process under vacuum (partial or total) where the foam would be crushed and pulverized under vacuum, and the vapor stream sent to a distillation process for liquid recovery. Solids are sent to a pelletizer for subsequent recycle. Once the foam is pulverized, the remaining solid portion is no longer a foam, it is polyurethane solids. These solids can be recovered, pelletized, or compressed and incinerated for fuel value, used as a concrete filler, or it is possible to recycled by glycolysis to chemically reduce the solids to a liquid polyol, which can be used again to make another polyurethane foam.
  • FIG. 4 illustrates a non-limiting example of a service center 400 including one or more systems 110, 120, 130, 140, 150 and 160 which can be connected to a mobile transport vehicle 420 to charge reclaimed refrigerant/refrigerant blends from system 410 through line 412, or recharge a refrigerant or refrigerant blend through line 412 which has been processed in system 410, and optionally withdraw spent refrigerant through line 422 from vehicle 420 for processing in system 410.

  • Step 2 liquid components of liquid mixtures are separated via a separation process such as distillation.
  • Step 3 non purified separated liquids could require further processing, e.g., additional distillation removal of NAGs, etc.
  • Step 4 the purified liquid components of Step 4 are compared with industry quality standards, and involve removal of moisture, solids, volatile impurities.
  • additive and/or tracers components are introduced to each purified individual component.
  • Step 6 separated, purified, addivized components can be remixed into other blends or used as pure components.
  • Fig. 6 illustrates a service center system 600 where a source of reclaimed/re-blended refrigerant 610 from a system such as that illustrated in Fig. 5 is connected to a refrigerant circuit 650 of a transport vehicle (not shown) which includes, generally in seriatim, charging valve 612, expansion device 614, heat exchange 620, compressor 630, heat exchange 640 and flow lines 613, 615, 622, 631 and 641.
