Refrigeration process and system for recovering cold from methane by refrigerants |
| 摘要 |
A refrigeration system includes a plurality of heat exchangers (E1, E2, E3) in cascade, each of said heat exchangers including: a flow (150) of cold-producing liquefied methane; a high-pressure flow (122) of a two-phase mixture of refrigerant fluids giving up in heat and including refrigerant fluids having a low normal boiling temperature; and a low-pressure flow (100) of a cold-producing two-phase mixture of said refrigerant fluids. |

1. A refrigeration system comprising a plurality of heat exchangers in cascade, each of said heat exchangers comprising;
a flow of cold-producing liquefied methane; a high-pressure flow of a two-phase mixture of refrigerant fluids giving up its heat and including refrigerant fluids having a low normal boiling temperature; a low-presssure flow of a cold-producing two-phase mixture of said refrigerant fluids; means for expanding said cooled high-pressure flow at the outlet from said cascade and for directing at least a portion thereof to at least one refrigeration heat exchanger passing a gas including CO2, said heat exchanger operating in a frosting cycle; means for obtaining a liquid phase from said high-pressure flow for cooling; and means for expanding said liquid phase and directing at least a portion thereof into said at least one refrigeration heat exchanger, said heat exchanger operating in a defrosting cycle. |
