Abstract

La presente invención se refiere a un proceso para separar hidrocarburos C4 y más pesados en alta recuperación y alta pureza a partir de un gas de carga comprendiendo aproximadamente 0-5 mol por ciento de hidrocarburos C5 y más pesados, 1-10 por ciento de hidrocarburos C4, 0-10 por ciento de hidrocarburos C3, 0-10 por ciento de hidrocarburos C2 y lo restante CH4 e inertes ligeros, que comprende: a) someter a presión el gas de carga a un nivel desde 10 hasta 40 atmósferas si no se encuentra al nivel mencionado; b) establecer y mantener el gas de carga a una temperatura de desde 2 grados hasta 38 grados C; c) enfriar el gas de carga en un desflemador a una temperatura superior preseleccionada, dentro de los límites desde -52 grados hasta -76 grados C, para formar un condensado líquido que contiene hidrocarburos C4+ y una fracción superior de vapor; d) retirar el condensado líquido desde el desflemador; e) retirar la mencionada fracción superior de vapor desde el desflemador y calentar por intercambio de calor indirecto contra la carga en el desflemador; f) expander con trabajo a la resultante fracción superior de vapor calentada en un expansor a una presión suficiente para generar una fracción fría teniendo el requerido valor de refrigeración y teniendo una temperatura desde aproximadamente 2 grados hasta 15 grados C abajo de la temperatura superior preseleccionada en el mencionado desflemador; y g) retirar la mencionada fracción fría desde el expansor y nuevamente calentar por intercambio de calor indirecto contra la carga en el desflemador.
