Abstract

A system for cooling a fluid particularly to a cryogenic temperature wherein a multicomponent refrigerant fluid is partially condensed, the liquid used to generate refrigeration to cool the product by recycle into an upstream portion of the warming leg of the refrigeration circuit, and the vapor, having a different composition than the liquid, is used to generate refrigeration at a colder temperature for further cooling of the product.
