Abstract

A method for cooling a single-component or multi-component stream, in particular a hydrocarbon-rich fraction, by indirect heat exchange with the refrigerant mixture of a refrigerant mixture circuit is described, the refrigerant mixture being compressed in at least two stages and being separated into a lower- . boiling refrigerant mixture fraction compressed to the ultimate pressure of the refrigerant mixture circuit and at least one higher-boiling refrigerant mixture fraction compressed to an intermediate pressure. According to the invention, the higher-boiling refrigerant mixture fraction (5) is pumped (Pll) to the pressure, of the lower-boiling refrigerant mixture fraction (8) and is combined with the lower-boiling refrigerant mixture fraction (8) before or immediately on commencement of indirect heat exchange (El). (The relevant figure is attached.)
