PROCESS AND APPARATUS FOR COOLING A FLUID ESPECIALLY FOR LIQUIFYING NATURAL GAS

In this process, which incorporates an integral cascade, the coolant mixture issuing from the penultimate stage (1B) of the compressor cycle (1) is delivered to a distillation apparatus (5) the head vapour of which is cooled (in 24) to a temperature significantly lower than the ambient temperature,...

Beschreibung
Zusammenfassung:	In this process, which incorporates an integral cascade, the coolant mixture issuing from the penultimate stage (1B) of the compressor cycle (1) is delivered to a distillation apparatus (5) the head vapour of which is cooled (in 24) to a temperature significantly lower than the ambient temperature, then separated into two phases (in 6C); the vapour stage is supplied to the last stage (1C) of the compressor, and the liquid phase constitutes a coolant fluid for the hot part (8) of the heat exchange line (7).
