Abstract

EN DONDE EL FLUIDO DE HIDROCARBURO ES LICUADO CONTRA UN CIRCUITO DE MEZCLA DE REFRIGERANTE EN CASCADA. EL PROCESO CONSISTE EN TRES CIRCUITOS DE MEZCLA REFRIGERANTE: A) EL PRIMER CIRCUITO DE MEZCLA DE REFRIGERANTE SIRVE PARA EL PRE-ENFRIAMIENTO, B) EL SEGUNDO CIRCUITO DE MEZCLA REFRIGERANTE SIRVE PARA LA LICUACION Y C) EL TERCER CIRCUITO DE MEZCLA REFRIGERANTE SIRVE PARA EL SUPER-ENFRIAMIENTO DEL FLUIDO DE HIDROCARBURO. LA MEZCLA REFRIGERANTE DE CADA CIRCUITO DE MEZCLA ES VAPORIZADA A UN SOLO NIVEL DE PRESION, MIENTRAS QUE EL INTERCAMBIO DE CALOR ENTRE EL FLUIDO DE HIDROCARBURO Y LA MEZCLA REFRIGERANTE DEL CIRCUITO DE PRE-ENFRIAMIENTO QUE SIRVE PARA PRE-ENFRIAR EL FLUIDO DE HIDROCARBURO SE LLEVA A CABO EN DOS O MAS INTERCAMBIADORES DE CALOR ESTRUCTURALMENTE IDENTICOS INSTALADOS EN PARALELO; ADEMAS, LA COMPOSICION DE LA MEZCLA REFRIGERANTE DEL CIRCUITO DE PRE-ENFRIAMIENTO SE LLEVARA A CABO A TRAVES DE UN COMPRESOR DE FLUJO DOBLE; Y LA COMPRESION DE LA MEZCLA REFRIGERANTE DEL CIRCUITO DE LICUACION SE LLEVA A CABO EN POR LO MENOS DOS ETAPAS, REALIZANDOSE LA COMPRESION EN LA PRIMERA ETAPA A TRAVES DE UN COMPRESOR DE FLUJO DOBLEWHERE THE HYDROCARBON FLUID IS LIQUEFIED AGAINST A CASCADE REFRIGERANT MIXING CIRCUIT. THE PROCESS CONSISTS OF THREE REFRIGERANT MIXING CIRCUITS: A) THE FIRST REFRIGERANT MIXING CIRCUIT IS USED FOR PRE-COOLING, B) THE SECOND REFRIGERANT MIXING CIRCUIT IS USED FOR LIQUIDATION AND C) THE THIRD SUPERIOR MIXING CIRCUIT -COOLING OF THE HYDROCARBON FLUID. THE REFRIGERANT MIXTURE FROM EACH MIXING CIRCUIT IS VAPORIZED AT A SINGLE PRESSURE LEVEL, WHILE THE HEAT EXCHANGE BETWEEN THE HYDROCARBON FLUID AND THE REFRIGERANT MIXTURE FROM THE PRE-COOLING CIRCUIT WHICH IS SERVED BY THE HYDROLOOKING PRE-COOLING CONDUCTED IN TWO OR MORE STRUCTURALLY IDENTICAL HEAT EXCHANGERS INSTALLED IN PARALLEL; ALSO, THE COMPOSITION OF THE REFRIGERANT MIXTURE OF THE PRE-COOLING CIRCUIT WILL BE CARRIED OUT THROUGH A DOUBLE FLOW COMPRESSOR; AND THE COMPRESSION OF THE REFRIGERANT MIXTURE OF THE LIQUEFIER CIRCUIT IS CARRIED OUT IN AT LEAST TWO STAGES, COMPRESSING THE COMPRESSION IN THE FIRST STAGE THROUGH A DOUBLE FLOW COMPRESSOR
