Abstract

LA CARGA DE GNL (1) ESTA REFRIGERADA POR EXPANSION PRIMARIA EN UNA TURBINA (21), INTERCAMBIO DE CALOR (2) Y EXPANSION SECUNDARIA ESTATICA (3). LA CARGA REFRIGERADA (4) ES FRICCIONADA EN UNA COLUMNA (5) DE DESNITROGENACION EN UNA FASE GASEOSA (10) FORMADA POR NITROGENO Y METANO, EVACUADA EN LA CABEZA DE LA COLUMNA 85) Y EN UNA CORRIENTE (11) DE GNL DESNITROGENADO, EXTRAIDO DEL FONDO DE ESTA COLUMNA. UNA PRIMERA FRACCION (6) Y UNA SEGUNDA FRACCION (8) DE GNL SON PURGADAS EN LA COLUMNA (5), PASAN AL INTERCAMBIADOR (2) PARA REFRIGERAR LA CARGA (1), DESPUES SON REINYECTADAS EN LA COLUMNA COMO PRIMERAS (7) Y SEGUNDAS (9) FUNCIONES DE REHERVIDO. LA FRACCION GASEOSA (10), DESPUES DE LA RECUPERACION DE SUS FRIGORIAS (13), ES COMPRIMIDA (15) PARA FORMAR UNA CORRIENTE (20) DE GAS COMBUSTIBLE.
