Abstract

Procedimiento para recuperar etano e hidrocarburos más pesados de un gas rico en metano, caracterizado porque comprende las etapas de: (a) pasar dicho gas a través de una serie de al menos dos etapas de refrigeración indirecta, con lo cual tiene lugar una licuación parcial del gas; (b) separar el líquido y vapores restantes; (c) vaporizar una porción de cada uno de los líquidos así formados pasándolos a través de etapas de reducción de presión; (d) separar los vapores de los restantes líquidos; (e) pasar el vapor de la última etapa de refrigeración a través de una turbina de expansión, con lo cual se licua parte de dicho vapor; (f) separar dicho líquido y el vapor restante; (g) pasar el líquido que resta después de la última etapa de reducción de presión de líquido, en relación de intercambio térmico con una porción del vapor de alimentación ya parcialmente enfriado, vaporizando con ello una porción de dicho líquido y formando a partir del mismo una mezcla de vapor y líquido; y (h) pasar dicha mezcla de vapor y líquido más el líquido del separador después de la turbina de expansión y el líquido del separador que sigue a la primera etapa de reducción de presión de líquido, como corrientes de alimentación separadas a una torre desmetanizadora.
