Abstract
The present invention relates to a refrigerant composition for refrigeration systems. The refrigerant composition can be a pre-cooled mixed refrigeration system with one or more phase separators. The refrigerant composition can include nitrogen; methane; ethane, ethylene, or combinations thereof; propane, n-butane, iso-butane, or combinations thereof; and neon, helium, or combinations thereof. Further, the invention includes the process for refrigeration using said refrigerant composition.
Claims4
