Abstract
Procedimiento para refrigeracion de etano, a través del empleo de un ciclo de refrigeracion que utiliza una mezcla de al menos dos fluidos refrigerantes, gases obtenidos mediante este procedimiento e instalacion de puesta en práctica. La presente se refiere a un procedimiento y una instalacion de refrigeracion de mezclas gaseosas, en miras a la separacion criogénica de los constituyentes de un gas bajo presion (1). El procedimiento comprende un ciclo refrigerante en el que un fluido (13), es separado en un balon separador (B2) en una fraccion menos volátil (4), util para la produccion de frío a una temperatura relativamente alta en un intercambiador (E1), y en una segunda fraccion más volátil (5), util para la produccion de frío a una segunda temperatura relativamente baja en un intercambiador (E2). Las fracciones (4, 5) recalentadas y expandidas son juntadas luego comprimidas en un compresor (K1). Una fraccion (26) salida del compresor (K1) es enfriada para proveer la fraccion (13).Ethane refrigeration procedure, through the use of a refrigeration cycle that uses a mixture of at least two refrigerant fluids, gases obtained by this procedure and installation of implementation. This refers to a procedure and an installation for cooling gas mixtures, with a view to cryogenic separation of the constituents of a gas under pressure (1). The process comprises a refrigerant cycle in which a fluid (13) is separated in a separator ball (B2) in a less volatile fraction (4), useful for the production of cold at a relatively high temperature in an exchanger (E1) , and in a second more volatile fraction (5), useful for the production of cold at a relatively low second temperature in an exchanger (E2). The superheated and expanded fractions (4, 5) are then combined into a compressor (K1). A fraction (26) compressor outlet (K1) is cooled to provide the fraction (13).
