Abstract

AIRE QUE SE COMPRIME EN UN COMPRESOR 200, SE REDUCE SU TEMPERATURA HASTA SU PUNTO DE ROCIO MEDIANTE EL PASO A TRAVES DE SUCESIVOS INTERCAMBIADORES DE CALOR 204, 206, 210 Y 212 (AGUA Y DIOXIDO DE CARBONO SON ALLI EXTRAIDOS EN LOS CAMBIADORES DE CALOR 204 Y 206). EL AIRE SE INTRODUCE EN UNA PRIMERA COLUMNA DE DESTILACION 216 A TRAVES DE UNA ENTRADA 218. ALLI SE SEPARA EN OXIGENO Y NITROGENO. EL VAPOR DE NITROGENO SE RETIRA DE LA PARTE SUPERIOR DE LA COLUMNA 216 A TRAVES DE LA SALIDA 228, SE CALIENTA, SE COMPRIME EN COMPRESORES 234 Y 236, SE ENFRIA, SE EXPANDE EN UNA TURBINA DE EXPANSION 238 Y ENTONCES SE PASA A TRAVES DE UN EVAPORADOR 220 PARA PROVEER EVAPORACION PARA LA COLUMNA 216. UNA CORRIENTE DE LIQUIDO RESULTANTE SE HACE PASAR A TRAVES DE UNA VALVULA DE ESTRANGULAMIENTO 244 Y SE RECOGE EL NITROGENO LIQUIDO EN UN SEPARADOR DE FASE 230. ALGO DE ESTE NITROGENO LIQUIDO SE DEVUELVE A LA COLUMNA 216 COMO REFLUJO, MIENTRAS LA OTRA PARTE SE EMPLEA PARA PROVEER PRODUCTO. SE RETIRA VAPOR DEOXIGENO ENRIQUECIDO EN ARGON DE LA COLUMNA 216 A TRAVES DE UNA SALIDA 260, Y SE SEPARA PARA FORMAR PRODUCTO ARGON EN UNA COLUMNA DE DESTILACION POSTERIOR 226 QUE SE EVAPORA MEDIANTE EL VAPOR DE LA PARTE SUPERIOR DE LA COLUMNA 216.
