Abstract:
A refrigeration system for cooling a charge gas by a binary refrigerant. The refrigeration system comprises n heat exchangers, n compressor stages, at least one separator and a demethanizer. By flowing depressurized refrigerant through all the subsequent heat exchangers and installing interstage coolers, the overall energy for the refrigeration system is reduced.
