Abstract

A process for compressing a gaseous fluid comprising a step (a) of injecting refrigerant during which a refrigerant substance is sprayed into the gaseous fluid to be compressed, and also a compression step (b), during which the passage of said gaseous fluid loaded with refrigerant substance is forced through said compressor in order to compress said gaseous fluid, the mass flow rate (Q3) of the refrigerant substance injected into the gaseous fluid represents between 1% and 5% of the mass flow rate of the gaseous fluid to be compressed, and the refrigerant substance is sprayed in the form of particles having a maximum dimension of less than or equal to 25 pm, and preferably less than or equal to 10 pm.
