Abstract

En el presente documento se describe un metodo para retirar refrigerante de un sistema de licuefaccion de gas natural en el que refrigerante mixto evaporado se extrae del circuito de refrigeracion de bucle cerrado y se introduce en una columna de destilacion para asi separarse en un vapor superior enriquecido en metano y un liquido inferior enriquecido en componentes mas pesados. Se extrae vapor superior de la columna de destilacion para formar una corriente enriquecida en metano que se retira del sistema de licuefaccion, y se reintroduce liquido inferior procedente de la columna de destilacion en el circuito de refrigeracion de bucle cerrado. Tambien se describen metodos para alterar la tasa de produccion en un sistema de licuefaccion de gas natural en el que se retira refrigerante como se describio anteriormente, y unos sistemas de licuefaccion de gas natural en los que pueden llevarse a cabo tales metodos
