Abstract

REFERIDO A UN METODO PARA MANTENER A UN VALOR DE TASA DE FLUJO Y A UNA TEMPERATURA PREDETERMINADOS, EL TORRENTE DE SALIDA DE GAS LICUADO "GL" DE UNA LICUEFACCION QUE COMPRENDE: A) COMPARAR EL VALOR DE LA TASA DE FLUJO GL PREDETERMINADO CON LA TASA DE FLUJO GL; B) COMPARAR EL VALOR DE TEMPERATURA GL PREDETERMINADO CON LA TEMPERATURA GL REAL; Y C) VARIAR LA REFRIGERACION PROPORCIONADA POR DICHO MEDIO DE INTERCAMBIO TERMICO EN RESPUESTA A LAS COMPARACIONES DE TASA DE FLUJO Y TEMPERATURA PARA REDUCIR LAS DIFERENCIAS. LA VARIACION DE LA REFRIGERACION PARA REDUCIR CUALQUIER DIFERENCIA DE TEMPERATURA GL SE INICIA ANTES DE LA VARIACION DE LA TASA DE FLUJO GL PARA REDUCIR CUALQUIER DIFERENCIA DE LA TASA DE FLUJO GL. SE REFIERE ADEMAS, A UN SISTEMA DE CONTROL QUE COMPRENDE: a) MEDIOS PARA COMPARAR EL VALOR DE TASA DE FLUJO PREDETERMINADO PARA EL TORRENTE DE SALIDA DE GL CON LA TASA DE FLUJO DE GL REAL; b) MEDIOS PARA VARIAR LA TASA DE FLUJO DE PRODUCTO GL REAL; C) MEDIOS PARA COMPARAR EL VALOR DE TEMPERATURA PREDETERMINADO PARA EL TORRENTE DE SALIDA DE GL CON LA TEMPERATURA REAL; Y d) MEDIOS PARA VARIAR LA REFRIGERACION PROPORCIONADA POR DICHO MEDIO DE INTERCAMBIO TERMICO EN RESPUESTA A LAS COMPARACIONES DE LA TASA DE FLUJO DE GL Y TEMPERATURA DE GL PARA REDUCIR LAS DIFERENCIAS; EN DONDE EL AJUSTE DE LOS MEDIOS PARA VARIAR LA TASA DE FLUJO REAL NO SE INICIA HASTA QUE LA REFRIGERACION HAYA SIDO AJUSTADA PARA REDUCIR CUALQUIER DIFERENCIA DE TEMPERATURA DEL GAS LICUADO
