    摘要: A method for providing refrigeration to a cryogenic rectification plant which enables the facile provision of varying amounts of refrigeration to the plant wherein a working fluid is pressurized in a recycle compressor, a first portion is at least partially condensed in a heat exchanger and passed into the plant, a second portion is cooled and then turboexpanded to generate refrigeration, the refrigeration bearing second portion passes refrigeration in the heat exchanger to the first portion to effect the condensation, and the resulting second portion is not passed into the cryogenic rectification plant but rather is returned to the recycle compressor.
