Measurements have been made of the amounts of cold and heat produced by a vortex tube operated with methane containing some carbon dioxide, and with Algerian natural gas, which has a high methane content. The effects of gas supply temperature and pressure have been investigated. The contribution of the Joule–Thomson effect to the total cooling has been calculated and allowed for. Vortex effect cooling decreases with lowering of the supply temperature and probably disappears at the gas liquefaction point. It is dependent on the pressure expansion ratio across the tube. The findings are compared with those of other workers and those predicted by vortex tube theories.

The disadvantage of the technological process of freezing food products using carbon dioxide is the irrational use of its waste vapors. From the authors’ point of view, it is desirable to use carbon dioxide not only directly on the line for freezing and cooling food raw materials. Cooling of carbon dioxide vapors after processing on freezing lines with further use for refrigeration looks promising, for example, for freezing food materials, for which the freezing temperature according to the technological instructions can be higher than the boiling point of carbon dioxide -78 ℃. An innovative refrigeration machine based on a Ranque-Hilsch vortex tube has been developed for cooling waste carbon dioxide for further use in the refrigeration processing of food products. It is based on carbon dioxide recovery technology.
